4-pole residual current circuit breaker PFIM-63/4/003-MW 235414

Residual Current Device – Safety and Reliability in Your Installation

This four-pole residual current device from Eaton (PFIM-63/4/003-MW) is a key element ensuring the protection of people and electrical equipment from the effects of short circuits and electric shock. Designed for both home and commercial use, it combines high performance with a durable construction.

Functionality and Application

The residual current device is designed to protect electrical circuits with a rated voltage of 400V and a rated current of 63A. Its main task is to quickly detect leakage currents to ground and disconnect the circuit, minimizing the risk of electric shock. The sensitivity to differential current is 0.03A (30mA), providing effective protection against the dangerous effects of ground faults. Mounting is on a DIN rail, making it easy to integrate with existing distribution boards. A mechanical lock prevents accidental switching on of the device after it has been switched off by the protection device.

Key Features and Benefits

• High short-circuit resistance: Short-circuit strength at 10kA guarantees reliable operation even in the event of high overvoltages.
• Wide range of conductors: The ability to connect multi-wire conductors with a cross-section from 1.5 mm² to 16 mm² and solid-core conductors from 1.5 mm² to 35 mm² provides installation flexibility.
• Universal application: AC type design ensures that the device effectively responds to alternating currents, which is important in most electrical installations.
• Safety of use: Rated impulse voltage withstand of 4kV provides additional protection against overvoltages.
• Durable construction: IP20 protection rating protects against finger contact and the ingress of solid objects larger than 12.5 mm, ensuring long-lasting and trouble-free operation of the device.
• Expandability: Compatibility with additional equipment allows the device to be adapted to specific installation needs.
• Optimal width: Occupies only 4 modules in width, saving space in the distribution board.
• Resistance to external conditions: Operation in ambient temperature from -25°C to +60°C allows installation in various environmental conditions.

Thanks to these features, the Eaton PFIM-63/4/003-MW residual current device is an investment in safety and peace of mind – both for professionals performing electrical installations and for end-users benefiting from a protected installation.
