The HD Series 16 V 300 A Heavy-Duty High-Current Magnetically Latching Bistable Relay (880086) is a remotely operated bistable relay disconnect designed for high-current circuits and applications that demand high performance, such as large inverter loads and high ambient temperature situations. Sealed to an IP67/IP69K rating, this heavy-duty automotive relay is built to withstand dust, water, and harsh weather, as well as environments with high shock and vibration.

The HD series bistable relay provides significant cost and weight benefits by eliminating the need to route heavy copper cables to more conveniently located mechanical-only disconnects. Cables can instead be routed directly to loads with the HD series relay positioned close to the battery or in line with the desired cable routing. Remote control of the HD latching relay can then be located in any convenient location on the vehicle with a finewire harness linking the HD relay to the control switch.
