DC disconnect switch 400 A | ED402

The ED402 range of switches have been designed to provide a rapid means of disconnecting batteries or other power supplies in the event of serious electrical faults. Whilst the switches are primarily intended for use with battery powered vehicles they are also suitable for use with static power systems. All types are capable of safely rupturing full load battery currents in the event of an emergency. The ED402 is a manually operated device with a simple over-centre spring mechanism which provides a "snap action" for both opening and closing of the main contacts. Auxiliary Contact: Denoted by 'A', a double circuit normally open, normally closed microswitch auxiliary contact can be fitted, ratings as shown below. Precautions: Note: 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.
