2CSA275901R9325 ASEA BROWN BOVERI Test Equipment Fault Detector

ARC FAULT & FIRE PROTECTION – 1P+N AFDD with integrated MCB detects series, parallel and earth arc faults, disconnecting circuits to reduce fire risk caused by damaged insulation, loose conductors or ageing wiring in final circuits. 32 A TYPE B WITH 10 kA CAPACITY – Rated 32 A with Type B tripping characteristic for circuits with low inrush currents; 10 kA breaking capacity (Icu) and 7.5 kA service capacity (Ics) at 230 V AC for dependable short-circuit protection. THERMAL-MAGNETIC & ENERGY LIMITING – Thermal-magnetic tripping mechanism with energy limiting class 3, dielectric test voltage 2.5 kV, contact position indication (red ON/green OFF) and electrical endurance up to 10,000 cycles. DIN RAIL INSTALLATION & FLEXIBLE CONNECTION – Two-module (35 mm) DIN rail device with failsafe bi-directional cylinder-lift screw terminals; supports busbar 10 mm², rigid 1–25 mm², flexible 1–16 mm² conductors, tightening torque 2.8 N·m. 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.
