ABB Protecta Plus DSE201 M C40 A300 Residual Current Circuit Breaker with Overcurrent Protection (RCBO) 1P+N 40A C Curve 300mA Type A 10/15kA 1 Module DIN Rail 2CSR275151R3404

40A C CURVE WITH 300MA TYPE A – Rated current 40 A with C tripping characteristic for circuits with higher inrush currents. 300 mA residual current sensitivity, Type A, suitable for AC and pulsating DC earth fault currents and supporting selective protection strategies. COMBINED RCBO PROTECTION – RCBO (Residual Current Operated Circuit-Breaker with Overcurrent Protection) combining residual current and thermomagnetic overcurrent protection in one compact 1P device. Protects against short circuit, overload and earth fault currents in accordance with IEC 61009. 10/15KA BREAKING CAPACITY – High short-circuit breaking capacity of 10 kA (up to 15 kA depending on installation conditions) ensures reliable interruption of fault currents in residential, commercial and light industrial low-voltage systems. COMPACT DIN RAIL INSTALLATION – Space-saving modular design for mounting on standard DIN rail systems. Screw terminal connection and toggle reset operation ensure straightforward installation and reliable integration into distribution boards for residential and commercial applications. 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.
