The MSD series of receptacles and plugs offers a tool-free solution for disconnecting an internal high-voltage battery pack and delivering short-circuit protection.

The device uses a two-stage lever system to open the high-voltage interlock (‘HVIL’) circuit prior to contact separation. All high-voltage conducting surfaces on the receptacles are touch-proof to IP2XB.

A second range is the Excel-Mate HVSL (high voltage safety lock) series of plugs and receptacles, which is designed for electric vehicle applications including power and signal interconnect.

One-way to three-way devices are available, rated up to 1kV and handling from 23A up to 350A.
