Eaton FRCMM-16/2/003-A Residual Current Circuit Breaker, 2-Pole, 16A, 30mA, Type A

The Eaton FRCMM-16/2/003-A is a high-performance 2-pole residual current circuit breaker (RCCB) engineered to provide robust electrical safety in modern installations. This device is designed to monitor electrical circuits for leakage currents, automatically disconnecting the power supply if a fault is detected to protect users from electric shock and prevent potential fire hazards. As a Type A device, it offers comprehensive protection by detecting both standard alternating current (AC) and pulsating direct current (DC) residual currents, making it a versatile choice for diverse electrical environments.

Advantages

This circuit breaker stands out due to its high reliability and precision in fault detection. By utilizing Type A technology, it ensures safety even in circuits containing modern electronic equipment that may produce non-sinusoidal leakage currents. Its compact 2-pole design allows for efficient space utilization within distribution boards, while the robust construction ensures long-term operational stability. The device is built to meet stringent safety standards, providing peace of mind for both residential and commercial electrical systems.

Suitable for

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

When it may not be suitable

This device is not intended for use in circuits requiring protection against overcurrent or short circuits, as it is a residual current circuit breaker and not a combined RCBO. It should not be installed in systems where the load exceeds the 16A rated current capacity.

Key specifications

• Rated current: 16A
• Sensitivity: 30mA
• Number of poles: 2
• Type: A

How to use

The Eaton FRCMM-16/2/003-A must be installed by a qualified electrician in accordance with local electrical regulations. It is typically mounted on a standard DIN rail within a consumer unit or distribution board. Once installed, the device should be tested periodically using the integrated test button to ensure the mechanical tripping mechanism remains functional. Proper wiring connections must be verified to ensure the input and output terminals are correctly secured.

What to consider before purchase

• Verify that the 16A rating is sufficient for your specific circuit load
• Ensure compatibility with your existing distribution board and DIN rail system
• Confirm that Type A protection meets the requirements of your connected electrical equipment

Usage recommendations

Regular testing of the residual current circuit breaker via the test button is recommended at least every six months to verify the integrity of the protection system.
