Single Pole 660A / 1500VAC - 3PU / 3PXU

There are two versions of the Single Pole connectors available, a plastic 3PU and a metal 3PXU version. The connectors have 2 auxiliary contacts in addition to the main contact.

The male connectors are protected by a safe (long) casing with an insulated tip, which prevents accidental touching (IP2X). This way the male version safely regulates the power supply.

The female connections are fitted with a silver-plated, self-cleaning sleeve (CuBe2). This version features a large number of contact points and is extremely heat-resistant (up to 200°C / 392°F). Very little pressure is therefore required to connect the male and female connectors.

Max. voltage: 1500 V / 110 V (phase / pilots)
Max. amperage: 660 A/ 30 A (phase / pilots)
No. of contacts: 1 phase + 2 pilot pins
Max. cable diameter:
                               Phase: 300mm²
                               Pilots: 6mm²
24 different setting options.
Watertight: IP66 - IP67
Temperature range: - 30° C / + 60° C
Mechanical shock resistance: IK8 (3PU - plastic) - IK10 (3PXU - metal)

Used materials:
Casing: 3PU - PA6 / 3PXU - AS7G
Inserts: 3PU - PA6 / 3PXU - PA6
Contact pins: silver-plated copper alloy
Wall box: PA6
Fastener: Neoprene
Screws: stainless steel
Cable connection: screw or crimp

All options are described in the new 3PU / 3PXU catalogue. View the digital version here..

The connectors are fitted standard with 2 pilots. The pilots are shortened, due to which they are the last elements to make contact and the first to lose contact. This prevents the tow components from being disconnected whilst under power. Naturally, all components must be assembled correctly. (Please refer to the brochure).

The connectors can be locked against unauthorized use. Contact us for all possibilities. The metal version features a practical easy-carry / closing handle.

Standards: IEC 60309-1 / NFC 63300 / Decision no. 88-1056
