Eaton PFIM-6301-S/A-MW Residual Current Circuit Breaker 4P 63A 0.1A Type S/A

The Eaton PFIM-6301-S/A-MW is a high-performance 4-pole residual current circuit breaker (RCCB) engineered to provide robust electrical safety and protection against fault currents in diverse power distribution systems. Designed for reliability, this device monitors electrical circuits to detect leakage currents, effectively mitigating the risks of electric shock and fire hazards. As a Type S/A selective device, it offers enhanced operational stability, making it an essential component for maintaining safety standards in both residential and industrial electrical installations.

Advantages

The primary advantage of this Eaton RCCB is its selective Type S/A functionality, which allows for coordinated protection in complex electrical networks by preventing nuisance tripping. Its 4-pole configuration ensures comprehensive coverage for three-phase systems, while the 63A rated current and 0.1A sensitivity provide a balanced approach to safety. The robust construction ensures long-term durability and consistent performance even in demanding environments, contributing to the overall integrity of the electrical infrastructure.

Suitable for

• Industrial power distribution systems
• Complex residential electrical installations
• Selective protection in multi-stage electrical circuits
• Protection against fault currents in three-phase networks

When it may not be suitable

This device is not intended for use in circuits requiring high-speed instantaneous tripping, as its selective Type S characteristic introduces a deliberate time delay. It is also not suitable for single-phase applications where a 2-pole device would be more appropriate and space-efficient.

Key specifications

• Number of poles: 4
• Rated current: 63A
• Rated residual operating current: 0.1A
• Type: S/A (Selective, AC and pulsating DC sensitive)
• Mounting type: DIN rail

How to use

The Eaton PFIM-6301-S/A-MW must be installed by a qualified electrician in accordance with local electrical codes and safety regulations. The device is designed for mounting onto a standard DIN rail within a distribution board. Ensure that the supply cables are correctly connected to the input terminals and that the load is connected to the output terminals, observing the correct phase sequence. After installation, the functionality of the device should be verified using the integrated test button to ensure it trips correctly under simulated fault conditions.

What to consider before purchase

• Verify that the 0.1A sensitivity meets your specific safety requirements.
• Ensure the 63A rated current is compatible with your circuit's load capacity.
• Confirm that the selective (S) time-delay feature is appropriate for your circuit coordination needs.
• Check the available space in your distribution board for a 4-pole module.

Usage recommendations

Regularly test the residual current circuit breaker using the test button at least every six months to ensure the mechanical and electrical components remain in optimal working order.
