ED80 Single Pole Single Throw On/Off (Part of the Emergency/Combined Disconnect Series) 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. • Uninterrupted current - no or infrequent load switching requirements (maintains a lower contact resistance). 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. The Use of Battery Disconnecting Switches in Electric Vehicles Modern battery powered electric vehicles are inherently very reliable and safe. 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. Uninterrupted Current Performance data provided should be used as a guide only.
