Residual current circuit breaker FRCMM-125/4/03, 10kA, 125A, 0.3A, Type AC, 4-pole, FRCmM series 187816

### Residual Current Device – Protection and Safety of Installation

This four-pole residual current device from Eaton's FRCmM series, with a rated current of 125A and a short-circuit strength 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 design and parameters make it a solution for both demanding home installations and commercial facilities.

Construction and Application

The FRCMM-125/4/03 circuit breaker is designed for mounting on a DIN rail, making it easy to integrate with existing distribution boards. A width of 4 modules allows for efficient use of space in the switchgear cabinet. Application in circuits with a voltage of 240V AC and a residual current sensitivity of 0.3A (Type AC) guarantee effective protection of people and equipment. Made of high-quality materials, it ensures durability and reliable operation even in harsh environmental conditions (operating temperature from -25°C to 60°C). A lock prevents accidental disconnection of the circuit breaker, increasing safety.

Key Features and Benefits

• High short-circuit resistance: Short-circuit strength at 10 kA ensures that the circuit breaker effectively interrupts the circuit in the event of a serious short circuit, minimizing the risk of damage and fire.
• Protection against electric shock: Sensitivity to residual current of 0.3A (Type AC) ensures a quick response in the event of a leakage current to earth, protecting users from electric shock.
• Universal mounting: DIN rail mounting simplifies installation and replacement of the circuit breaker in existing distribution boards.
• Durability and reliability: Made of high-quality materials guarantees long life and trouble-free operation of the device.
• Safety of use: The lock prevents accidental disconnection of the circuit breaker, ensuring continuity of supply and minimizing the risk of unauthorized changes to settings.
• Wide range of wires: The ability to connect solid wires with a cross-section of 1.5…50 mm² and stranded wires 1.5…16 mm² provides flexibility in selecting wires tailored to specific installation needs.
• Compliance with standards: Meets the required safety standards, confirming its high quality and reliability. The rated impulse withstand voltage Ui is 4 kV and the rated insulation voltage Ui is 440 V.

Thanks to these features, the FRCMM-125/4/03 circuit breaker is an optimal solution for anyone who values safety, reliability and comfort in their home or business.
