Eaton FRCmM-40/2/003-A Residual Current Circuit Breaker 2P 40A 30mA Type A

The Eaton FRCmM-40/2/003-A is a professional-grade 2-pole residual current circuit breaker (RCCB) engineered to provide essential electrical safety in modern power distribution systems. This device is designed to detect and interrupt leakage currents, offering robust protection for both residential and commercial electrical installations. By monitoring the balance between phase and neutral conductors, it ensures that any hazardous fault current is identified and disconnected immediately, thereby safeguarding users and equipment from potential electrical shocks and fire risks.

Advantages

This residual current circuit breaker stands out due to its high reliability and precision in fault detection. As a Type A device, it is capable of detecting both sinusoidal AC residual currents and pulsating DC residual currents, making it a versatile choice for modern environments containing electronic equipment. The robust construction ensures long-term operational stability, while the clear mechanical indicators allow for quick status verification. Its design facilitates easy installation in standard distribution boards, providing a seamless integration into existing electrical safety setups.

Suitable for

• Residential electrical distribution boards
• Commercial office buildings
• Protection of circuits with electronic loads
• General purpose electrical safety applications

This device may not be suitable for industrial environments requiring higher breaking capacities or specific protection against high-frequency leakage currents. It is also not intended for use in DC-only power systems or circuits where the leakage current characteristics exceed the operational parameters of a Type A device.

Key specifications

• Rated current: 40A
• Rated residual operating current: 30mA
• Number of poles: 2
• Type: A
• Mounting type: DIN rail

To use the Eaton FRCmM-40/2/003-A, it must be installed by a qualified electrician in accordance with local electrical regulations. The device is mounted onto a standard DIN rail within a distribution cabinet. Once installed, the circuit breaker should be connected to the supply and load lines according to the wiring diagram provided on the housing. Regular testing is essential to ensure the mechanism remains functional over time.

What to consider before purchase

• Verify that the rated current of 40A matches your circuit requirements
• Ensure the 30mA sensitivity is appropriate for your specific safety needs
• Confirm compatibility with your existing DIN rail distribution board
• Check if a Type A device is required for your specific load types

It is recommended to perform a manual test of the device using the integrated test button at least every six months to ensure the tripping mechanism is operating correctly.
