ED80

EMERGENCY DISCONNECT

The ED80 is a manually operated device with a simple over-centre spring mechanism which provides a snap action for both opening and closing the main contacts.  As with all our ED Disconnecting switches, the ED80 has been designed to provide rapid means of disconnecting batteries or other power supplies in the event of serious electrical faults.  The ED80 is suited for uninterrupted current loads.

The ED80 is primarily intended for use with battery powered vehicles but is also suitable for use with static power systems.  It is capable of safely rupturing full load battery currents in the event of an emergency.  The ED80 is easy to install (see drilling details) and is 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.
