The Westhomes WSB5L Series RCCB is a high-performance residual current circuit breaker designed for use in low-voltage electrical distribution systems.
With advanced safety features, durable construction, and 6kA/10kA fault handling capability, the WSB5L RCCB is the ideal choice for dependable circuit protection in demanding environments.
With a rated breaking capacity of 6kA or 10kA, this RCCB provides superior short-circuit protection for critical infrastructure and high-load environments. It is CE and CB certified, ensuring compliance with international safety and performance standards.
Suitable for AC 240V/400V, 50Hz systems, and available in rated current options up to 63A, the WSB5L RCCB provides comprehensive protection against earth leakage, overload, and short circuit faults. When the residual current exceeds a specified threshold, the device responds instantly to disconnect the power supply, ensuring the safety of people and equipment.
Built with high-impact, flame-retardant materials, this RCCB offers compact design, long service life, and stable performance, making it ideal for applications in residential buildings, commercial offices, distribution networks, and industrial facilities. It also supports manual switching under normal conditions, meeting the needs of daily circuit operations.
