2CSA275901R9404 ASEA BROWN BOVERI Test Equipment Fault Detector

COMBINED ARC FAULT & OVERCURRENT PROTECTION – 1P+N AFDD with integrated MCB designed to detect series, parallel and earth arc faults while providing overload and short-circuit protection, supporting fire risk reduction in final circuits. 40 A TYPE C PERFORMANCE – Rated current 40 A with Type C tripping characteristic for circuits with moderate inrush currents; 10 kA breaking capacity at 230 V AC ensures high short-circuit withstand capability in distribution boards. INTEGRATED SELF-TEST & LED STATUS – Continuous internal self-monitoring verifies correct operation; front test button enables functional checks and LED indication supports clear identification of operating and fault conditions. COMPACT DIN RAIL INSTALLATION – Two-module width (35 mm) device for DIN rail mounting with screw terminals and thermal-magnetic tripping; IP40 protection rating and operating temperature range from -25 °C to +55 °C for reliable panel integration. ABB PROTECTA PLUS SYSTEM – Part of the ABB Protecta Plus modular distribution system for indoor installations, offering high internal accessibility, removable internal modules for simplified wiring, insulated neutral and earth bars, and an expandable cabinet concept for flexible electrical distribution solutions.

S-ARC1 M IS A 1P+N ARC FAULT DETECTION DEVICE (AFDD) WITH AN INTEGRATED MCB IN TWO MODULES, FOR THE PROTECTION AGAINST SHORT-CIRCUIT CURRENTS, OVERLOAD, EARTH ARC FAULTS, PARALLEL ARC FAULTS AND SERIES ARC FAULTS.
