Description
The D0100/D0900 Arc-Flash relays provide a simple and cost-
effective 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.

Arc-Flash Relay
A0200 (180˚)/A0300 (360˚) Light Sensors
Line-of-sight light sensor detects an arc as small
as 3 kA within a 2-m half-sphere. Available in
180˚ or 360˚; 5, 10, or 15 m cable.
D0400/D0500 Junction Box for parallel connection
of more than 2 sensors for one relay. Designed
to connect up to 8 sensors, and is available with
and without indication. Max. 2 junction boxes
can be connected to one Arc-Flash relay.
