- Designed to provide a rapid means of disconnecting batteries or other power supplies in the event of serious electrical faults.
- Primarily intended for use with battery powered vehicles they are also suitable for use with static power systems.
- Capable of safely rupturing full load battery currents in the event of an emergency.
- Secured with supplied M5 posidrive mounting screws.
- Lockable versions feature a key.
Precautions:
When fitted with magnetic blowouts the polarity marked on the contact housing must be observed when connecting the main terminals. Ensure that the switches are installed in a position where heavy arcs emanating from the switch cannot damage or electrically jump across to adjacent parts. The switch is to be used to rupture current in an emergency or as a no-load isolator.
Do not use as a regular On-Load Switching Device.
