Eaton FRCMM Residual Current Circuit Breaker 4P 63A 30mA Type G/A 10kA

The Eaton FRCMM Residual Current Circuit Breaker is a high-performance 4-pole device engineered to provide robust electrical protection in both residential and industrial environments. With a rated current of 63A and a sensitivity of 30mA, this circuit breaker is designed to detect leakage currents and disconnect the circuit promptly, thereby preventing hazardous situations. The Type G/A classification ensures that the device is resistant to nuisance tripping, offering a reliable solution for modern electrical systems that require high stability and safety.

Advantages

This residual current circuit breaker offers superior reliability due to its advanced design, which minimizes the risk of unwanted tripping caused by transient surges or electrical noise. The 10kA short-circuit breaking capacity provides an extra layer of protection, ensuring that the device can handle significant fault currents without compromising the integrity of the electrical installation. Its 4-pole configuration makes it versatile for various three-phase power distribution setups, while the high-quality construction ensures a long service life and consistent performance under demanding conditions.

Suitable for

• Residential electrical distribution boards
• Commercial building power systems
• Industrial machinery and equipment protection
• Installations requiring protection against AC and pulsating DC fault currents

This device may not be suitable for applications requiring a different sensitivity level, such as specialized medical equipment or high-sensitivity fire protection circuits that demand lower milliampere thresholds. It is also not intended for use in circuits exceeding its rated current of 63A or in environments where the ambient temperature or environmental conditions fall outside the manufacturer's specified operating range.

Key specifications

• Number of poles: 4
• Rated current: 63A
• Rated residual current: 30mA
• Short-circuit breaking capacity: 10kA
• Type: G/A (short-time delayed, pulse current sensitive)

Installation should be performed by a qualified electrician in accordance with local electrical regulations. The device is typically mounted on a standard DIN rail within a distribution board. Ensure that the supply voltage matches the device specifications and that all connections are tightened to the recommended torque to prevent overheating or poor contact. Regular testing using the integrated test button is recommended to verify the mechanical functionality of the tripping mechanism.

What to consider before purchase

• Verify that the 63A rating is appropriate for your total circuit load
• Ensure the 30mA sensitivity meets the safety requirements for your specific application
• Confirm that the 4-pole configuration matches your electrical system layout
• Check the available space in your distribution board for DIN rail mounting

Regular maintenance and periodic testing of the residual current circuit breaker are essential to ensure continued protection. It is recommended to press the test button at least every six months to confirm that the device trips correctly and remains in good working order.
