ABB Residual Current Circuit Breaker with Overload Protection 50A Current Rating 4-Pole 30mA Trip 2CSR274101R1505

ABB 2CSR274101R1505 Residual Current Circuit Breaker with Overload Protection from the DS200 series is engineered to deliver comprehensive protection against overload, short-circuit currents, and earth leakage faults. It is designed primarily for residential, industrial, and commercial electrical installations requiring reliable circuit protection.

This device features a rated current of 50A and a 4-pole configuration, enabling it to monitor multiple circuits effectively. The breaker includes a 30mA trip sensitivity, enhancing safety by detecting earth leakage currents promptly and minimizing risks associated with electrical hazards.

With an instantaneous tripping characteristic Type B, the breaker responds rapidly to fault currents, preventing damage to electrical equipment and enhancing personnel safety. The lever reset actuator allows easy manual resetting after fault clearance, while screw terminals ensure reliable electrical connections.

The breaker operates at a rated AC voltage of 400V AC and possesses a breaking capacity of 10kA, suitable for handling high fault currents common in commercial and industrial environments. Compliance with IEC/EN 60947-2, REACH, and RoHS standards guarantees adherence to international quality and environmental directives.

Compact in size - 105mm wide, 93mm high, and 69mm deep - this device fits well within distribution panels where space is limited. The Type A earth leakage protection supports detection of sinusoidal alternating earth fault currents, making it versatile for various applications.

Equipped with 30mA trip sensitivity for safety against leakage currents. Provides short-circuit and overload protection to circuits. Instantaneous Type B tripping characteristic for quick fault response. Screw terminal and lever reset actuator for secure connections and ease of operation.

Compact dimensions fit limited space distribution boards. Rated for 50A current and 400V AC voltage operation. Breaking capacity of 10kA for robust fault handling. Complies with IEC/EN 60947-2, REACH, and RoHS standards.

This ABB residual current circuit breaker is ideally suited for use in industrial, residential, construction, and commercial electrical installations requiring advanced protection against electrical faults and leakage currents.
