D0100 And D0900 Arc Detecting Relay

Arc Detecting Relay 24-220 V DC for station battery The D0100 is a detecting relay which can monitor up to 16 arc detectors in parallel through junction boxes D0400 or D0500. In case of an arcing fault, the relay generates a fast tripping pulse, less than 1 mSec., to the circuit breaker(s) supplying the instal-lation. The arcing time is thus reduced to the mechanical opening time of the circuit breaker, The relay is solid state with complete isolation between input and output. Thus the relay and the circuit breaker may have different pilot voltages. The TEST-position on the relay is used to test the tripping without opening the circuit breaker. The 2 free signal contacts is for remote indication of arcing fault trip and indication for absence of pilot voltage - or for indication of the TEST-function is activated. The sensitivity to light is adjustable on the front plate SENS.ADJ knob within 1-12mA. The range is 2.000-24.000 lux enabling you to use the sensors under different light conditions, indoor light, sunlight etc. The preset is 6mA/ 6.000 lux. This product is complementary to the following products: - A0200 Detector - A0300 Detector - D0700 Current Relay - D0400 Junction Box - D0500 Junction Box The D0900 is a detecting relay which can monitor up to 16 arc detectors in parallel through junction box D0400. In case of an arcing fault, the relay generates a fast tripping pulse, less than 1 mSec., to the circuit breaker(s) supplying the installation. The arcing time is thus reduced to the mechanical opening time of the circuit breaker, The relay is solid state with complete isolation between input and output. The relay has energy stored in a storage capacitor charged with a DC voltage to trip the circuit breaker. The TEST-position on the relay is used to test the tripping without opening the circuit breaker. The 2 free signal contacts is for remote indication of arcing fault trip and indication for absence of pilot voltage - or for indication of the TEST-function is activated. Both contacts are activated after tripping as the relay normally disconnects its own supply voltage. The sensitivity to light is adjustable on the front plate SENS.ADJ knob within 1-12mA. The range is 2.000-24.000 lux enabling you to use the sensors under different light conditions, indoor light, sunlight etc. The preset is 6mA/ 6.000 lux. This product is complementary to the following products: - A0200 Detector - D0400 Junction Box
