- 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 uninterrupted high current battery powered systems such as those found in Telecommunication Power Distribution Units.
- Capable of safely rupturing full load battery currents in the event of an emergency.
- Secured with supplied M5 posidrive mounting screws.
Precautions:
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.
Spare Parts are not available – this contactor is deemed non-serviceable.
