The CARLING TECHNOLOGIES PB-Series circuit breaker is a versatile device designed to provide comprehensive protection in a single package. Utilizing the hydraulic magnetic principle, it offers precise operation and performance even in challenging environments with extreme temperatures. This RCBO (Residual Current Circuit Breaker with Overcurrent Protection) integrates ground fault protection with the familiar overcurrent tripping characteristics of a standard circuit breaker. Its temperature stability eliminates the need for derating and minimizes nuisance tripping. The PB-Series is ideal for applications such as boats, marinas, and areas near water, where electrical shock hazards are a concern. It detects lower-level ground faults that ordinary circuit breakers may miss, reducing the risk of fires and electrical shock. The breaker's features include overload, short circuit, and ground fault protection, handle or rocker style actuators, and a trip-free mechanism for enhanced safety.
