What are power connectors?

Power connectors are the plug for connecting an electrical device and a power source. There are two main types of power connector – residential and industrial. Plugs carry either AC (alternating current) or DC (direct current). AC connections allow a device to be connected directly to an electrical supply. DC plugs come in standard sizes and are not interchangeable for safety reasons.

Powerlock Connectors

Phase 3’s Powersafe heavy duty devices are fully compatible with other manufacturers like ITT Litton Veam Powerlock for industrial use. The Powersafe series is based on a standard format as utilised by the UK and European temporary power industries. Powerlock type devices are mechanically keyed and identified by wiring colours coding standards, therefore they are considered the safest industry device. High current single pole plugs and three phase sockets are available within the range for AC/DC circuits. The single and three phase electrical device is an industry leader in quality, hence why it is considered that the electrical connectors are a perfect replacement for CamLock. Phase 3’s range includes bimetal connectors for industry users using aluminium cables.

Phase 3’s Showsafe circular plug devices are fully compatible with Amphenol Socapex for event industry use. Our  UL approved mutli-pin lighting circular connectors have been developed to offer the highest levels of reliability and safety. Phase 3’s super robust construction of the 19 pin circular socapex electrical device ensures continual and reliable operation.

The Powersafe Sequential Mating box is a three phase power distribution box designed for use with temporary electrical installations with a current rating of up to 800 amps. On the low voltage mating box there are powerlock Panel Mounts for three phases plus Neutral and Earth secured onto a panel board. The generator connection point is compatible with other manufacturer’s, like Litton, VEAM, ITT Cannon.
