SD150

NO - SP - ST

The SD150 has been designed to provide a rapid means of disconnecting batteries or other power supplies in the event of serious electrical faults.

The SD150 combines the dual function of a manual disconnect and coil operated line contactor.  The benefits of this design include compact size and reduced installation costs combined with an electrical capacity sufficient for small and medium size electric vehicles.

Whilst the switches are 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.
