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 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.

However, even when sophisticated electronic controllers are used it is desirable to have a means of disconnecting the battery in the event of an emergency, such as a vehicle failing to stop or an electrical short circuit. In many countries it is mandatory to fit one or more devices to achieve an emergency disconnection of the battery. 0 & & # m Current (Amperes) Contact Performance Key: Connection Diagram Uninterrupted Current Performance data provided should be used as a guide only.
