Arc-Flash Monitoring
D0100 SERIES & D0900 SERIES
Arc-Flash Relay
Description
The D0100/D0900 Arc-Flash relays provide a simple and costeffective solution for Arc-Flash monitoring. Two light sensors
can be connected directly to one relay, or optional junction
boxes allow up to 16 sensors per relay.
Light Sensors react to light and are available with 180º or 360º
detection area. Sensors are supplied with 5, 10 or 15 m of
cable and a mounting bracket. 1-2 sensors are recommended
per cubicle or drawer.
Installation Diagram
Place sensors in direct line
of sight to possible arc faults,
preferably pointing down from the ceiling.
