Eaton FRCdM Series Residual Current Circuit Breaker 40A 3-Pole 300mA Type B 10kA 220V DC 240V AC 167905 FRCDM-40/4/03-G/BFQ

The Eaton FRCdM Series Residual Current Circuit Breaker, model 167905 FRCDM-40/4/03-G/BFQ, is a high-performance electrical protection device engineered for demanding industrial and commercial environments. Its primary function is to safeguard personnel and equipment against electrical faults caused by earth leakage, electrocution risk, and fire hazards caused by unintended current flow. The circuit breaker features 3-pole configuration and is rated for continuous operation at 40A.

This device offers high-sensitivity trip action at 300mA, conforming to Type B protection characteristics, capable of detecting both AC and DC earth leakage currents, making it suitable for systems with variable frequency drives and complex loads. Its electromagnetic tripping mechanism secures reliable performance and robust operation even during surge events, with an impressive breaking capacity of up to 10kA.

Designed for versatile power systems, this RCCB accommodates rated voltages up to 220V DC and 240V AC. It installs easily into control panels using standard DIN rail mounts and features screw terminal connectors for secure wiring. The unit includes twin-purpose wiring terminals that support cabling from either the top or bottom of the breaker, enhancing flexibility for control cabinet layouts.

Durability is ensured through an extended electrical lifespan, capable of up to 4,000 operations, and a UV-protected housing, allowing safe outdoor or sunlight-exposed deployments. Its compact design, measuring 80mm in height, 70mm in width, and 70.5mm in depth, facilitates efficient space utilization in electrical enclosures.

Safety and compliance are guaranteed, as the breaker meets international standards including EN 45545-2, IEC 61373, and IEC/EN 61008, providing peace of mind for end-users and facility managers. Its transparent designation plate supports clear labeling and fast identification within electrical systems.

Typical applications include industrial power distribution, commercial facilities, critical infrastructure, manufacturing, variable frequency drive installations, solar inverter arrays, and any environment requiring advanced earth leakage protection with high current tolerance.
