Eaton PFIM-100/4/01 Residual Current Circuit Breaker, 4-Pole, 100A, 100mA, Type AC

The Eaton PFIM-100/4/01 is a high-performance 4-pole residual current circuit breaker (RCCB) engineered to provide essential electrical safety in demanding environments. This device is specifically designed to monitor electrical circuits for leakage currents, automatically disconnecting the power supply when a fault is detected to prevent electrical hazards, fire risks, and damage to sensitive equipment. Built to industrial standards, it offers robust protection for complex electrical systems requiring a 100A rated current and 100mA sensitivity.

Advantages

This residual current circuit breaker stands out for its reliability and precision in detecting AC residual currents. By integrating this component into your electrical distribution board, you ensure a high level of protection for both personnel and infrastructure. The 4-pole configuration allows for versatile application in three-phase systems, providing comprehensive monitoring across all phases and the neutral conductor. Its durable construction ensures long-term operational stability even in intensive commercial or industrial settings.

Suitable for

• Industrial electrical distribution systems
• Commercial building power installations
• Protection of three-phase electrical circuits
• General equipment safety against leakage currents

This device is not suitable for detecting DC residual currents, as it is specifically designed as a Type AC RCCB. It should not be used in applications where high-frequency components or DC fault currents are expected, as these may interfere with the device's ability to trip correctly.

Key specifications

• Number of poles: 4
• Rated current: 100A
• Rated residual operating current: 100mA
• Type: AC

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 and load requirements are compatible with the device specifications before connection. Once installed, the integrated test button should be used periodically to verify the mechanical functionality of the tripping mechanism.

What to consider before purchase

• Verify that the 100mA sensitivity meets the specific safety requirements of your installation
• Ensure the 100A rated current is sufficient for your circuit load
• Confirm that the system requires Type AC protection rather than Type A or B
• Check available space on the DIN rail within your electrical enclosure

Regular testing of the residual current circuit breaker using the built-in test button is recommended at least every six months to ensure the device remains in optimal working condition.
