| The
museum has a few, German made, dated or obsolete heavy duty and three phase
plugs and sockets. Nos. 1, 3, 4, 5, 7 and 8 are made by Busch-Jaeger
Electro GmbH (now part of the ABB Group). Nos. 2 and 6 have been made by ABL (now ABL SURSUM). The models nos. 1 and 2, and corresponding plugs 5 and 6 are no longer in use. Perilex plugs and sockets (nos. 3, 4, 7 and 8), designed in 1951 by Busch-Jaeger, are still available, but nowadays almost exclusively used for electric stoves. Other three-phase applications are mostly connected according to IEC 60309 standards. |

| 1, 5 | Obsolete 250V, 25A single phase socket and plug. The items in the museum collection were used in a university laboratory when the standard domestic network offered 110V (common practice in parts of the Netherlands up to 1950s). |
| 2, 6 | Obsolete 380V, 10A three-phase socket and plug. The configuration of the three power pins resembles that of plug no. 5, but the overall spacing between pins is different (25 mm for plug no. 5, versus 31 mm for no.6). 380 Volt refers to times when domestic networks offered 220V, rather than the today's European 230V standard. |
| 3, 7 | Perilex 380-400V, 16A three-phase socket and plug. Perilex plugs were commonly used in the western part of Germany (former BRD), Netherlands and Sweden, and can be regarded as an IEC 60309 precursor. |
| 4, 8 | Perilex 380-400V, 25A three-phase socket and plug. The pin configuration is identical to the 16A version (no. 7), except for the orientation of the central, flat blade protective earth. |
