EATON FRCMM-63/4/03-G/F Residual Current Circuit Breaker 4P 63A 0.3A Type G/F

The EATON FRCMM-63/4/03-G/F is a high-performance 4-pole residual current circuit breaker (RCCB) engineered to provide robust electrical protection in demanding environments. This device is specifically designed to detect and interrupt fault currents, significantly reducing the risk of electrical hazards in industrial and commercial power distribution systems. With its advanced design, it ensures consistent operational stability and safety for connected equipment and personnel.

Advantages

This residual current circuit breaker offers superior reliability through its specialized Type G/F configuration, which is optimized for complex electrical installations. The unit is built to withstand transient surges, minimizing the likelihood of nuisance tripping while maintaining high sensitivity to actual leakage currents. Its durable construction and high-quality components ensure a long service life and dependable performance even under continuous load conditions.

Suitable for

• Industrial electrical distribution boards
• Commercial building power systems
• Protection of sensitive electronic equipment
• Installations requiring high immunity to surge currents

When it may not be suitable

This device is not intended for residential applications where a lower sensitivity or different tripping characteristic is required by local building codes. It is also not suitable for direct current (DC) systems or circuits that exceed its rated current capacity of 63A.

Key specifications

• Number of poles: 4
• Rated current: 63A
• Rated residual operating current: 0.3A
• Type: G/F (Short-time delayed, pulse current sensitive)

How to use

The installation of this residual current circuit breaker must be performed by a qualified electrician in accordance with local electrical regulations. The device is designed for mounting on a standard DIN rail within an electrical distribution cabinet. Ensure that all power supply lines are disconnected before beginning the installation. Connect the incoming supply cables to the top terminals and the outgoing load cables to the bottom terminals, ensuring that all connections are tightened to the specified torque to prevent overheating.

What to consider before purchase

• Verify that the 63A rated current matches your circuit requirements.
• Ensure the 0.3A residual current rating is appropriate for the specific safety application.
• Confirm that the 4-pole configuration is compatible with your existing electrical panel layout.

Usage recommendations: Regularly test the functionality of the device using the integrated test button to ensure the tripping mechanism remains operational. It is recommended to perform this check at least every six months to maintain optimal safety standards.
