That's arc welding power, 50 volts at 5 amps. I fail to see how a connector is going to last more than a few cycles under load.

Presumably this would be a negotiated system like USB-PD, where only a tiny amount of power is available at connection and with pins physically configured to ensure breaking connection in order you may be able to shut down the higher power before the main contacts disengage).
