The Westhomes WSB3L Series RCCB 1P+N 63A residual current circuit breaker is designed for high-safety performance in low-voltage AC systems operating at 230V/400V, 50Hz.
The Westhomes 1P+N 63A RCCB is a cost-effective, high-performance solution for secure electrical distribution, combining compact design, advanced protection, and easy installation for small-scale and medium-scale power systems.
With its 1P+N configuration and rated current of 63A, this miniature RCCB ensures swift disconnection during ground faults or leakage events to protect both people and connected equipment.
Ideal for modern electrical distribution networks, the WSB3L RCCB offers advanced functionality in a compact and durable design. Its high-sensitivity leakage detection triggers a rapid response to any abnormal current flows, preventing potential electric shocks, electrical fires, or system failures. Built with flame-retardant, impact-resistant materials, the product is both safe and long-lasting, suitable for installations where 1-pole protection with neutral is required.
This 1P+N 63A RCCB is widely used in residential buildings, commercial facilities, distribution boxes, and control cabinets, where both compact size and reliability are crucial. The device also supports overload and short circuit protection, making it a multifunctional solution for modern power safety management.
