The Merlin Gerin Multi9 series RCCB (Residual Current Circuit Breaker) is a world-class electrical safety device designed to provide superior protection against earth leakage, electric shock, and fire hazards. As a core component of the iconic Multi9 range, these leakage protectors are engineered to detect minute residual currents and instantly disconnect the power supply, ensuring the safety of both personnel and equipment. Available in a comprehensive current range from 6A to 40A (C6 to C40), the Multi9 series is the industry standard for reliability in residential, commercial, and industrial power distribution boards.

Constructed with high-quality flame-retardant materials and high-precision electromagnetic trip mechanisms, the Merlin Gerin RCCB offers stable performance even in harsh electrical environments. Its modular design allows for seamless integration with other Multi9 DIN-rail components, making it the preferred choice for electrical contractors and panel builders globally. Whether you are protecting a high-load air conditioning circuit or a standard domestic lighting loop, this leakage protector ensures consistent, fail-safe operation.
