- Designed to provide a rapid means of disconnecting batteries or other power supplies in the event of serious electrical faults.
- Combines the dual function of a manual disconnect and coil operated line contactor.
- Primarily intended for use with battery powered vehicles, they are also suitable for use with static power systems.
- All types are capable of safely rupturing full load battery currents in the event of an emergency.
Spare Parts are not available – this contactor is deemed non-serviceable.
