Perilex and pre-IEC 60309 plugs and sockets |
 |
 |
 |
| In
Germany several types of heavy duty and 3-phase plugs and sockets have
preceded the now commonly used IEC 60309 standard. One of them, the Perilex type is still used for non-industrial purposes. Other models shown here are now obsolete. |

| 1, 2 | Perilex 380-400V, 16A three-phase socket
and plug. Perilex plugs were commonly used in the western part of
Germany (former BRD), Austria, Netherlands and Sweden, and can be
regarded as an IEC 60309 precursor. The Perilex socket schemes show two different types of wiring: T - S - R - 0(=N) and L1 - L2 - L3 - N (* 0 = neutral contact). Explanation is given in note 2, below. The advanced position of PE contact ensures that earth contact is made first. |
| 3, 4 | Perilex
380-400V, 25A three-phase socket and plug. The pin configuration is
identical to the 16A version (nos. 1, 2), except for the orientation of
the
central, flat blade protective earth. |
note 1 |
Perilex has been designed in 1951 by Busch-Jaeger Electro GmbH (now part of the ABB Group). From 1975 the use of Perilex for new industrial installations is no longer allowed in Germany and Austria, instead IEC 60309 devices have to be used. In homes (kitchens), hospitals and small businesses you will still find Perilex. |

2 |
Perilex socket schemes show that two
different types of wiring can be found. The original Perilex pin-out is
shown top left. A three-phase motor connected to this socket will turn
anti-clockwise. However, the 1988 (?) version of German DIN VDE
0100-550 defined clockwise as standard direction of rotation for AC
motors. Designation of contacts R(L1) and T(L3) have been swapped. |
| 5, 6 6a | 5-pin, 3-phase socket (5) and corresponding plug (6) rated at 16A - 220/380V. They resemble to IEC 60309 16A-230/400V, but key position differs. Position of HST 165 socket earth contact is at 7h, while it is 6h for IEC 60309 16A. Moreover plug diameter of HST 165 is 12 mm smaller than 16A 5-pin IEC 60309. HST 165 is designed for application where confusion with IEC 60309 must be avoided. Manufacturer: Dutch company HATEHA. The significance of "E-flash-J" logo is unknown. {ES} |

250V, 25A single phase socket and plug. Two
plugs of this type in the museum collection have the name SCHUKO on
its
housing (see note below). One
has been made by ABL (Albert Büttner, Lauf, bei
Nürnberg; now ABL SURSUM, Bayerische Elektrozubehör
GmbH),
the other by Leopold Kostal (Lüdenscheid, Germany). The socket shown
has
brand name: Presto, trademark of Presto-Vedder GmbH, Dortmund, Germany. Another socket in the collection has a
logo
that has been used
between 1951 and 1979 by Busch-Jaeger Electro. |
| 9, 10 | Obsolete
three-phase socket and plug, rated at 10A-380V (socket) and 16A-380V
(plug). 380 Volt refers to times
when domestic networks offered 220V,
rather than the today's (continental) European standard of 230V. The porcelain inner part of socket no. 9 has been made in East Germany by VEB IKA (existed from 1958 till 1958; IKA stands for Installationen, Kabel und Apparate, Leipzig) and has a quality nr. 1 mark (see nr. 11). The housing of the socket shows also an unknown logo that is also found on plug no. 15. Plug no. 10 has been made by Bayerische Elektro-Zubehör in Lauf bei Nürnberg, Geramny (ABL). |
| 11 - 13 |
Three-phase 10A - 220/380V flush type socket, made by Ernst Maté in Wien, Austria. Socket and plug have the same safety characteristics as 10-16A - 250 V Schuko devices. Therefore the designation SCHUKO was allowed for the 380V three-phase socket and plug. Earth and neutral clips are linked with a jumper (green arrow in image no. 12). Image no. 13 shows that for a technician it was easy to remove the jumper. Combining earth and neutral was an often chosen solution if a separate protective earth wire was not available. {WN} |
| 14 | Three-phase 15A - 380V plug, made by Gebrüder Merten in Gummersbach, Germany (GMG). The central line pin has two grooves. Plugs with this deviant type of pin - and matching sockets - were used when different electricity tariffs were used. Lighting tariff (Lichttarif) had to be paid for illumination and relative low wattage equipment in homes. Domestic tariff (Haushalttarif or Küchentarif) for heating, electric stoves, washing machines, irons, vacuum cleaners etc. Commercial tariff (Gewerbetarif) had to be paid for workshops etc. Pins with two grooves were used for domestic applications. See also page on uncommon continental European plugs and sockets. {WN} |  source: 1935 AEG catalog (edited) |
| note |
The name Schuko is commonly used for single phase (2-pin) plugs with earth clips, but above all Schuko (Schutzkontakt) refers to two characteristics that offers enhanced safety: (i) sockets are recessed which makes it impossible to touch pins under tension, and (ii) earth contact is made first. Socket nos. 7 and 9 are recessed, and the earth pin of plug no. 8 and neutral and earth strips of no. 10 make contact first. |

| 15 | Three-phase 380V, 10A plug, made in the former German Democratic Republic. The triangular mark with number 1 indicates that plug complied with TGL quality level 1 (click here for explanation of DDR Gütezeichen). The inset bottom right shows an unknown logo that probably refers to the manufacturer. {PM} |
| 16 | Three-phase
plug with flat pins, rated at 15A - 380V. Pin dimensions: 8 mm wide,
2.5 mm thick, and 23 mm (line) and 26 mm (neutral, earth) long. Neutral
pin is indicated as 0 (zero, according to Dutch pin nomenclature). Life
pins are indicated as B, G, R*. Manufacturer: Hazemeyer in
Hengelo, Netherlands. Dating: probably 1950s-'60s. * In Dutch, B could be blauw or bruin (blue, brown) wire colour , G: groen (green) and R: rood (red). However, until 1970 colours for R, S and T (respectively L1, L2 and L3) were green, black and dark blue. From 1970 it is brown, black and grey. {WN} |
| 17 | Lockable
three-phase plug made in the 1930s by Kontakt AG in Frankfurt am Main.
Images and details of this rare plug are given on a separate page. {RH} |

| 18 - 20 | Obsolete 3-phase, 3-pin + earth, 32A - 500V connector (type C13a) and plug (type C3a). Metallic cast. In the past power pins were indicated by R, S and T (now respectively: L1, L2 and L3). Also a similar 16A - 380V version has existed, see nos 15-16. In the 1960-80s these devices were quite popular in workshops. Brand name: Hazemeyer, a Dutch company, now being a part of Eaton Corporation. The double H logo first has been used for Hazemeyer Hengelo (Dutch town were the company was based), but later - after merging with Holec - it could also be used for Hazemeyer Holec and finally for Holec Holland. |
| 21 | Hazemeyer Hengelo
16A - 500V, 3-pin + earth, 3-phase plug.
The plug has been used for decades in a barn, hence the clear signs of
corrosion. The design is comparable to, but smaller than the 32A model,
shown right. See also plug no. 22. {MK} |
| 22 |
Hazemeyer Hengelo 16A - 380V, 3-phase +
earth plug, type C433z. Pin diameter: 4.9 mm. Spacing between line
pins: 15 mm. Top image: plug in upside down position to show off the earth pin. Bottom image: shows the large metal ground plate. Earth pin is directly connected to the plate that keeps also the black, insulating polymer block with three power pins in position. Dating: 1970s - early 1980s. It was the last model in a large range of plugs and connectors with power pins in a row. In the 1980s they were succeeded by IEC 60309 industrial standard models. {JW} The iron cast 16A - 500V plug shown in image no. 21 (left) is similar to the 16A - 380V plug no. 22. Power pin size and spacing is identical, but earth connector is different. |
| 22a |
Classic 3-phase wall socket rated at 16A -
220-380V, with earth contact. Matching plug is shown in image 22. Late twentieth century IEC 60309 became the industrial wiring standard, but functional applications according to "Nederlandse Passing" (Dutch fitting)* are still in use. For replacement the Dutch company HATEHA has 16A and 32A material in stock. Image 22a shows the HPW16 wall socket. "Nederlandse Passing" refers to 3-phase plugs and matching sockets with four round pins (nos 22 and 22a) only. Not to 18-21. |

3-phase, 4-pin, 25A - 220/380V connector and plug*. The shown model
with
cast iron body and steatite inside has been made by VEB
Elektroschaltgeräte Grimma in the 1960s-70s, but the design by
Walther-Werke dates to the 1930s. VEB Elektroschaltgeräte Grimma
was the successor of Ferdinand Walther's Walther-Werke, founded in 1897
in Grimma near Leipzig. See list of German manufacturers for details about both
companies. The
triangular mark with number 1 indicates that plug and connector
complied with TGL quality level 1 (see also caption to no.
29). {PM} * Besides the shown 25A model, the range of Grimma connectors consisted of: 10A, 16A, 25A, 40A, 63A and 100A connectors. |
| 27- 28 | Obsolete,
DDR single phase plug and connector, rated at 10A - 250V. Pin
diameters: 4 mm (power pin 1 and 2), and 5 mm (earth pin = 0). Plug and
connector have a zinc alloy die casting and are water and dust
protected according to IP 68 grade. Plug has a TGL top quality
Gütezeichen. Material has once been used by the army of the German
Democratic Republic. {WM} |
| 29 | Marks
on plug and connector nos. 27 and 28. Top left-mid: top quality mark
given by DAMW*; top right: SLF logo of the yet unknown manufacturer (see
note below); bottom: TGL** mark and
number of plug no. 26 (connector no. 27 has number 57-1023). * Deutsches Amt für Material und Warenprüfung (comparable to [western] German VDE). ** Technische Güte- und Lieferbedingungen (comparable to DIN). Click here for details. |
note on SLF |
Nowadays (2016) two companies exist that use the abbreviation SLF. (1) Spindel- und Lagerungstechnik Fraureuth (near Zwickau, Sachsen). Already in GDR times they produced rolling bearings. Although their current logo bears some resemblance to the SLF logo on plugs, there is no indication that they ever have made plugs. (2) The DDR-Army has used plugs, identical to nos. 27-28, that were designated as 'System Finow, made by SLF'. The company Spezialgeräte und Leuchtenbau Finow in Eberswalde, near Berlin, could be related to the Finow System. However, it is unknown whether the company was already active in the GDR. Note that the SLF logo on plugs seems to show a stylized lamp. |

30, 30a Three-phase socket rated at 10A -380V with contacts for 14 pins (4.0 mm diameter each), see fig. 30a. Four contacts for L1 (R1, R2, R3 and R4), four L2 (S1-4), four L3 (T1-4), an earth contact connected to the metal housing and a contact indicated as no. 13 (significance unknown). Each contact can be wired separately. {KC} The socket was mounted in a switching cabinet together with various CEE 17 (IEC 60309) sockets. It is unknown for which application the 14 contact socket was intended. Details about HTS have not been found. The US company TE-Connectivity is using the abbreviation HTS for the heavy duty product line. It could be that HTS was a German company working on behalf of the US company. Dating: 1970s |
| German standard VDE 0620 applies to fixed socket-outlets for AC only, with or without earthing contact, with a rated voltage greater than 50 V but not exceeding 440 V and a rated current not exceeding 32 A. (source) |
