ABB Residual Current Circuit Breaker with Overload Protection 20A 240V AC Thermal Magnetic 2CSA255103R1205 DS-ARC1 B20 A30

ABB 2CSA255103R1205 DS-ARC1 B20 A30 is a Residual Current Circuit Breaker with Overload Protection designed for electrical safety in industrial, commercial, and residential systems. It features a 20A current rating and 1-pole configuration suitable for single-phase circuits with rated AC voltage of 240V. The device uses a thermal magnetic tripping mechanism combined with Type B tripping characteristics to provide reliable protection against overcurrent and fault currents.

Part of the DS-ARC1 series, this compact 3-module wide circuit breaker integrates residual current detection with overcurrent protection and arc fault detection capability. It meets IEC and RoHS standards and is designed for easy installation on a DIN rail with compatibility for System Pro M Compact busbars, which simplifies wiring without requiring additional cables.

The circuit breaker has a breaking capacity of 6 kA, ensuring high safety under fault conditions. It features a trip sensitivity of 30mA to guard against earth leakage faults and incorporates Type A earth leakage protection for enhanced security. The toggle switch reset actuator allows convenient manual resetting after tripping.

Additional practical features include double slot terminals enabling supply connections from either top or bottom, facilitating flexible installation. The device includes LED indicators and two test buttons to verify proper functionality of the arc fault detection device (AFDD) and residual current device (RCD) components. Continuous internal self-testing ensures ongoing operational integrity.

With dimensions measuring 85mm height, 52.5mm width, and 85mm depth, the product is compact yet robust. Manufactured in Italy, ABB guarantees high quality and adherence to stringent safety norms.
