MX 3 Pin Powercon Male Plug Connector MX3FCB 20 Amp 250V (MX-2831)

This cable-mount male plug carries the FCB keying that mates specifically with MX's MX3MPB-keyed female socket, keeping the correct pairing enforced by the connector's physical shape rather than relying on an installer to remember which cable goes where. At 20 amps and 250V, it's rated for the same serious power loads as the rest of MX's Powercon-style line, and the locking mechanism keeps the connection secure once mated. Building a custom power cable with this plug on the end means it can only connect to the correctly-keyed socket, which is exactly the kind of built-in mistake-proofing that matters on a power distribution system with multiple connection points.
