The Powersafe Sequential Mating Box is an electrical connection point for single pole connectors on three phase electric power up to 800 amps. The Powersafe Box has a sequential mating locking system to ensure safety circuits are connected first and disconnected last (FMLB). Furthermore, the keyed design eliminates the possibility of electrical connection errors. The powerlock box accepts connection of Powersafe power connectors and is compatible with other manufacturers. The Powersafe powerlock box is a 1P heavy duty electrical device that is suitable for low voltage power distribution.
The Powersafe box can be panel-mounted, providing the most cost-effective solution, or brought out to an external or safe position. Large power connections can be catered for by stacking the units allowing for even the largest of low-voltage supplies to be connected in a safe way.
The box utilises standard Powersafe Connectors in either drain or source. The power distribution box has mechanically keyed ports to ensure correct phase connection, the ports are lockable to prevent accidental disconnects and colour coded to suit international wiring colour standards.
The Powersafe Sequential Mating Box can operate with an internal microswitch that can be used as a signal path to operate electrical protection devices. A 3 pin connector on the rear of the box is provided for easy connection. The switch can be used to trip the mains supply should someone open the Lock key whilst the supply is present.

Connections are safe: Earth and Neutral connections must be connected first and Live Lines 1 to 3 cannot be mated in the wrong order due to the innovative sequential mating mechanism. The distribution box is also IP67 rated when mated, allowing a waterproof connection. A special locking key is required to plug or unplug all connectors so only authorised persons in possession of the key can connect and disconnect the Powersafe Box.
Easy Install: The panel connectors are mounted in a single enclosure. There is no need to fabricate flange holes for five individual panel mounts.
Insulated: Some electrical regulations required hardware to be made of non-conducting materials. The Powersafe Box is insulated, giving greater freedom in fastener specification. The materials used are heavy duty, flame retardant
Intelligent Technology: A remote control function can be configured via the rear-mounted connector to disconnect the power should someone try to unlock the box.
Harsh Environment Application: We can supply an optional lid as a protective cover that is built in and forms part of the mating sequence giving IP65 protection to the un-mated box. When the connectors are installed the box is rated IP67.
This product is compatible with VEAM Powerlock box connectors and other manufacturers.
