The Weltrus RCCB (Residual Current Circuit Breaker) is designed to protect people and property from electric shock and fire hazards caused by earth fault currents. By detecting leakage currents in the circuit, the RCCB instantly disconnects power, significantly reducing the risk of injury or electrical fire. This device is an essential safety component for modern electrical systems, offering fast response times and reliable fault detection. The Weltrus RCCB supports multiple pole configurations (3P/4P) and operates across a wide rated current range (50–800A), making it suitable for both low-load domestic circuits and high-capacity industrial applications. Built to CE-certified standards, the RCCB provides mechanical durability and stable electrical performance, ensuring long-term safety and reliability.
