Product Description

ABB 2CSA255103R1105 DS-ARC1 B10 A30 Residual Current Circuit Breaker with Overload Protection is a high-quality electrical safety device designed for precise protection and fault detection in residential, commercial, and industrial electrical installations. Providing a current rating of 10A and trip sensitivity of 30 mA, this 1-pole breaker safeguards circuits by combining residual current detection with integrated overload protection.

This circuit breaker adheres to Type B tripping characteristics, suitable for detecting a wide range of AC and pulsating DC earth leakage currents, making it ideal for modern electrical systems with electronic devices.

The unit supports a rated AC voltage of 240V AC with a robust breaking capacity of 6 kA. The thermal magnetic tripping mechanism ensures reliable and fast disconnection during overload or short-circuit conditions. Practical features include a toggle switch reset actuator and screw terminals to securely mount and connect the device on a DIN rail.

The compact three-module design with dimensions 85 mm (height) x 69 mm (depth) x 52.5 mm (width) allows efficient use of electrical panels and switchgear. Installation flexibility is enhanced by double slots allowing power supply from both the top and bottom for cable and busbar connections, supporting the System pro M Compact busbar accessories.

Additional safety and diagnostic support comes from LED indicators for network troubleshooting and two test buttons to verify both arc fault detection and residual current device functionality. The device runs an internal self-test continuously to ensure operational readiness.

Certified to RoHS and IEC standards, the breaker promises compliance with international electrical safety norms. Manufactured in Italy, it belongs to ABB's DS-ARC1 series, a trusted range for ensuring arc fault and residual current protection in various electrical environments including industrial, commercial, HVAC, and residential systems.

This product is designed for integration in electrical control panels, industrial automation systems, and electrical distribution boards. It provides critical protection against arc faults, overloads, earth leakage, and short circuits, reducing fire risks and equipment damage.

Compatible with System pro M Compact busbars and accessories for streamlined panel wiring. Ideal for deployment in building automation, manufacturing facilities, electrical utilities, and safety compliant installations.
