Detailed Product Description
Our 1P+N Residual Current Circuit Breaker with Overcurrent Protection (RCBO) offers a comprehensive solution for electrical safety by combining the functionalities of a residual current device (RCD) and a miniature circuit breaker (MCB) into a single compact unit. This device continuously monitors leakage currents and trips instantaneously when detecting earth faults or overcurrent overloads, significantly reducing the risk of electric shock and fire hazards.
Designed in a 1P+N (single pole + neutral) configuration, this RCBO swiftly disconnects faulty circuits and protects users and equipment by interrupting unexpected leakage currents and current overload conditions. Engineered to meet rigorous international standards like IEC 61008/61009, it ensures superior reliability in various electrical environments.
The breaker features fast tripping characteristics with a rated residual operating current as low as 30mA, offering exceptional sensitivity for domestic, commercial, and light industrial applications. Its robust construction guarantees long-term stable performance under frequent switching and variable electrical loads.
Installation is straightforward through standard DIN rail mounting compatible with most distribution boards, making maintenance and replacement user-friendly. Whether protecting electrical circuits from earth leakage, overload, or short circuit faults, this RCBO is the ideal protective device ensuring electrical safety compliance and peace of mind.
