Protection Relays & Controls 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 Features & Benefits Features Compact module Fits into wide range of Arc-Flash applications BENEFITS Trip time <1 ms Limits Arc-Flash damage and risk of injury Two optical sensor types Point sensors with 180° or 360° detection area depending on specific installation Single Arc-Flash relay can monitor 2 sensors or junction boxes Sensor expansion Junction box allows for up to 16 sensors per Arc-Flash option relay (8 sensors/box) Dual sensor input Place sensors in direct line of sight to possible arc faults, preferably pointing down from the ceiling.
