Powerlock Single Pole 500A 800A Connectors

Powersafe Powerlock from P3 Connectors UK is a range of single pole electrical connectors used for high current, low voltage, heavy duty & harsh environment applications ( 1000V/ac and 1500V/dc) used in either Temporary or Permanent installations. Fully certified by UL, VDE, RoHS and CE standards, P3 Powerlock connectors are available in 500A and 800Amp versions. Powerlock connectors are available in either Source (Male Contact / Female Insulator) or Drain (Female Contact / Male Insulator) format, both Panel Mount or Inline. Please note: When selecting your inline connectors, it's the cable size, cross-sectional area (CSA termination), that determines which connectors are required. Powersafe Powerlock connectors are available with either Set Screw termination for cables up to 120mm² and with Crimped termination for cable sizes between 150mm²  & 300mm² The Powersafe set-screw M40A 120mm²  (= 382Amps) termination is the industry standard for cable with a CSA of between 25mm & 120mm² . A series of adapter bushings ( reducers ) are available to match the diameter of the cable being used. ie 95/70/35/25mm² Additionally, these  set-screw M40A 120mm² connectors can accept most H07RN-F cable of up to 150mm² (= 441Amps) Compatible with ITT/Veam Powerlock connectors​.

In an emergency power application, the generator is generally the source and would be fitted with Panel Source (panel-mount) connectors. A cable assembly is then required to connect between the generator (source) and the item receiving the power (drain). This cable will usually have a drain connector on one end a source connector on the other however, options are also available with M12 Lug connections.
The source connectors are intended to have their permanent connection at the supply of electrical energy (such as a connection to the electrical grid or an emergency generator), and the drain connectors are intended to have their permanent connection at the equipment receiving power. The role of male and female connectors is opposite to traditional usage in other designs of power connector -the Powerlock source connector has a male pin and the drain connector has a female receptacle. This does not however, compromise safety because the gap between the plastic insulating cap on the male pin of the source connector and the surrounding plastic housing is too small to insert a human finger. The female drain connector also has a spring-loaded plastic cap to prevent dirt ingress and casual contact with the electrical contact; however with sufficient pressure this can be displaced with a finger.
The Powerlock mating system ensures Powersafe Powerlocks cannot be mis mated ( wrongly matched ) or disconnected accidentally under load, all colours are keyed differently.
