ED1800 Single Pole Single Throw On/Off
(Part of the Emergency/Combined Disconnect Series)
1800A
The ED1800 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. Designed for use with
uninterrupted high current battery powered systems such as those found in Telecommunication
Power Distribution Units, all types are capable of safely rupturing full load battery currents in the event
of an emergency.
•
Uninterrupted current - no or infrequent load switching requirements (maintains a lower contact resistance).
The ED1800 is a manually operated device with a snap action for both opening and closing of the main
contacts. They have paralleled double breaking contacts with silver alloy tips which are weld resistant,
hard wearing and have excellent conductivity. The ED1800 is easy to install (see drilling details) and can be
mounted using the main terminal busbars or secured with supplied M5 posidrive mounting screws on the frame
of the device.
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.
