Residual current circuit breaker 6kA type AC HNC-63/4/003 194695

Safety and reliability in your electrical installation

The Eaton HNC-63/4/003 residual current circuit breaker (RCCB) is a key element in protecting electrical installations, both in residential and industrial buildings. It provides protection against electric shock, fire, and equipment damage by reacting to abnormalities in the circuit. Its robust construction and high short-circuit breaking capacity (6kA) guarantee reliable operation even in harsh conditions.

Functionality and application

This four-pole RCCB has a rated current of 63A and a residual current sensitivity of 0.03A (30mA). Designed to operate at 230V and 50Hz, it protects against the effects of AC fault currents – alternating currents that can pose a threat to health and life. Thanks to the ability to connect wires with a cross-section from 1.5 mm² to 35 mm² (solid) and 1.5 mm² to 16 mm² (stranded), it is compatible with a wide range of wires and installations. Mounting is done on a standard DIN rail, which simplifies integration with existing distribution boards.

User comfort and durability

The Eaton HNC-63/4/003 also features practical solutions for installers and users. It has a lock preventing accidental switching on after switching off, and a clear contact position indicator (red/green) informs about the current status of the device. Additionally, the possibility of connecting wires from both the top and bottom of the device, as well as the use of double terminals (screw/busbar), facilitate installation and connection of wires. According to the manufacturer's recommendations, the circuit breaker should be tested regularly – every 6 months – to ensure its proper operation for a long time. The device width of 4 modules allows for efficient use of space in the distribution board.
