TE Connectivity’s SCHRACK Relays

Bistable/latching power relays (8-120A)

Power bistable relays can be used to switch applications in energy-saving manner. These relays retain their switched position if supply voltage fails, preventing loss of information on the current switching status. Just a short switching impulse of a few milliseconds is enough to switch the relay into a defined switch position.
