The Westhomes WSB3L Series RCCB is an advanced electronic type residual current operated circuit breaker designed for AC 230V/400V, 50Hz power distribution systems.
This AC 230V/400V RCCB is a crucial component for modern distribution systems where personal safety and equipment protection are paramount.
Engineered to detect and eliminate electrical faults in real-time, this RCCB provides highly effective protection against electric shocks, earth leakage currents, short circuits, and overloads in both residential and commercial environments.
With a rated current up to 63A, the WSB3L RCCB ensures that circuits are disconnected immediately upon detection of leakage or overload, safeguarding human life and electrical equipment. This model is particularly optimized for use in low-voltage distribution systems operating at 230V single-phase or 400V three-phase, making it a reliable choice for office buildings, residential homes, industrial units, and commercial installations.
Constructed with a high-impact resistant and flame-retardant housing, the WSB3L series is compact yet robust, supporting long-term safety and performance. Its advanced internal structure offers precise tripping characteristics and consistent operational reliability, ensuring enhanced protection in a wide range of applications.
