Littelfuse Selco Arc Detection Catalog - 1

Short Form Catalogue Arc-fault Protection System Protection of Switchboards • Improve personnel safety. Arcing faults in switchboards can cause severe damage against material as well as personnel. • Minimize production down time. The main issue is that no two arcing are the same, and it is therefore very difficult to know in advance how to prevent them. Whenever arcing occurs the pressure generated by the rapid increase in temperature is strong enough to break off cabinet doors. Further the light of the arcing, ultraviolet, and infrared, is dangerous for personnel, eyes and skin. • Reduce damage to material and the cost of repair or replacement. All of the above points should be taken into consideration in the Total Cost of Ownership, TCO, of a switchboard, and by using the SELCO Arc Detecting Relays you will be able to reduce these costs and eliminate the points listed.

Arc-fault Protection System The SELCO Arc-fault Protection System is based on experience with arc protection since 1962. The system units are built into boxes all fitting 35mm DIN-rails. Front plates are dimensioned to fit into the 45mm slot in the cover plates of a DIN-system. Arc Detecting Relay/ Current Relay/Time Relay To be placed in the switchboard or in connection with it. It is recommended that the Arc Detecting Relay, the Current Relay and the Time Relay are installed in the relay box or otherwise separated from the circuit breaker to be tripped. The Arc Detecting Relay is...

Arc-fault Protection D0100 Arc Detecting Relay for 24-220V DC battery supply For use with: · A0200 · A0300 · D0400 · D0500 · D0700 The D0100 is a detecting relay which can monitor up to 16 arc detectors in parallel through D0400 or D0500 Junction Boxes. In case of an arcing fault, the relay generates a fast tripping pulse, less than 1msec., 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. Thus the relay and the circuit breaker...

Arc-fault Protection D0500 Junction Box with Indication D0700 Overcurrent Relay For use with: · D0100 For use with: · D0100 · A0200 · A0300 The D0500 is designed to connect up to 8 detectors in parallel and has a separate indication of which detec-tor(s) caused tripping by means of a red LED for each detector. The red LED is lit when the light intensity exceeds 6.000lux. on the detector, but it turns off again if the intensity goes below 6.000lux. At 12.000lux. the arc detecting relay is triggered, the active LED’s are latched and a yellow LED (TRIP) is turned on. All LED’s remain turned on...
