Residual current circuit breaker type G/B 4-pole FRCdM-25/4/003-G/B 167892

Residual Current Circuit Breakers Eaton FRCdM – Safety and Reliability in Installation

The FRCdM-25/4/003-G/B residual current circuit breaker is a key element in protecting electrical installations, providing protection against electric shock and the effects of short circuits. The device is designed to protect circuits in residential and public buildings, as well as in industrial facilities. The 4-pole design allows for the protection of the entire circuit, and the G/B characteristic provides effective protection against both overloads and insulation faults.

Functionality and Application

This circuit breaker, with a rated current of 25A and a tripping current of 0.03A, effectively reacts to earth leakage currents, disconnecting the circuit when a hazard is detected. This is particularly important in wet rooms or areas exposed to water. DIN rail mounting simplifies installation and integration with existing modular equipment. The use of a mechanical lock increases safety during maintenance and repairs, preventing accidental switching on of the circuit breaker.

Why choose the FRCdM-25/4/003-G/B circuit breaker?

• Versatile application: ideal for protecting lighting, socket outlets and other electrical appliances.
• High reliability: short-circuit strength of 10kA guarantees stable operation even in difficult conditions.
• Safety of use: mechanical lock prevents accidental switching on during maintenance work.
• Easy installation: standard DIN rail mounting allows for quick and trouble-free installation.
• Wide operating temperature range: the device retains its properties in the temperature range from -25°C to 60°C.
• Compliance with standards: meets the safety requirements specified in relevant European standards (IP20).
• Expandability: compatible with additional accessories, allowing it to be adapted to individual installation needs.

The circuit breaker is designed for durability and reliability. The housing made of high-quality plastic provides resistance to mechanical damage and external factors. The cross-section of the connectable multi-wire cable up to 16 mm² and single-wire cable up to 35 mm² allows connection of cables of different thicknesses, adapting to the requirements of a specific installation. The rated impulse withstand voltage of 4 kV provides additional safety in the event of overvoltages in the electrical network. The width of the device, 4 modules, allows for efficient use of space in the distribution board. The B characteristic provides fast tripping in the event of overloads, protecting the installation from damage caused by prolonged load.
