Residual Current Circuit Breaker FRCMM-125/4/003, 10kA, 125A, 0.03A, Type AC, 4-pole, FRCmM series 187814

Residual Current Device – reliable installation protection

This four-pole residual current circuit breaker from Eaton's FRCmM series, with a rated current of 125A and a breaking capacity of 10kA, is a key element ensuring safety in every electrical installation. Designed to protect against electric shock and fires caused by short circuits to earth, it provides a reliable barrier against potential hazards. Its compact size (4 modules wide) makes it easy to install even in crowded distribution boards.

Functionality and technical parameters

The circuit breaker is characterized by high sensitivity to leakage currents (0.03A), which guarantees a quick response in the event of a fault. Designed for use in AC circuits, it meets strict safety standards. The possibility of mounting on a DIN rail and a wide range of permissible wire cross-sections (1.5 - 50 mm² for solid and 1.5 - 16 mm² for stranded wires) provide flexibility during installation. A mechanical lock prevents accidental disconnection of the circuit breaker, increasing safety.

• High surge current resistance: Withstands surge currents up to 0.25 kA, ensuring stable operation even in difficult conditions.
• Wide operating temperature range: Trouble-free operation in the temperature range from -25°C to 60°C makes it suitable for use both indoors and in environments with variable thermal conditions.
• Compliance with standards: Meets safety and quality requirements, ensuring correct operation and compliance with regulations.
• Solid construction: Made of high-quality materials, guaranteeing long-lasting and trouble-free operation.
• Expandability: Compatible with additional Eaton accessories, allowing it to be adapted to individual installation needs.

Application and installation

The FRCMM-125/4/003 circuit breaker is used in electrical installations in residential, commercial and industrial buildings. It is ideal for circuits with high loads requiring reliable protection against electric shock and fires. Installation is carried out by snapping onto a standard DIN rail, which is quick and easy. The rated insulation voltage Ui is 440V and the rated impulse withstand voltage Uimp is 4kV, ensuring safe operation of the device in various network conditions.
