Heavy Duty DC Battery Disconnecting Switches
The "ED" and "SD" ranges of Disconnecting switches have been designed to
provide a rapid means of disconnecting batteries or other power supplies
in the event of serious electrical faults. The switches are primarily
intended for use with battery powered vehicles but are also suitable for
use with static power systems.
All types are capable of safety rupturing full
load battery currents in the event of an emergency.
