This series is the single-pole bi-stable version of the ADR electronicbattery disconnect switches.
It protects the vehicle in potentially explosive environments in case of emergency according the European Dangerous Goods Transport Regulation and is operated with an emergency ON-OFF switch.
Switches are bi-stable with zero consumption, that is, the device absorbs current only during the commuting phase when the electrical circuit is switched ON or OFF and no further consumption to keep the ON or OFF status.
