Residual current circuit breaker PFIM PFIM-100/4/03-S/A 290220

Safety and reliability in your electrical installation

Residual Current Device (RCD) PFIM-100/4/03-S/A is a key element ensuring the protection of people and equipment in electrical installations. Designed by the renowned company Eaton, this four-pole switch effectively protects against the effects of short circuits and earth leakage currents, minimizing the risk of electric shock and equipment damage. Its solid construction and high quality workmanship guarantee long-lasting and trouble-free operation.

Characteristics and application

The PFIM-100/4/03-S/A switch is intended for use in circuits with a rated voltage of 400V and a rated current of 100A. Thanks to its sensitivity to differential current of 0.3A (type A), it effectively detects even small leakage currents, providing a quick response and circuit disconnection. The mechanical lock prevents accidental switching on of the switch after it has been switched off by the operation of the RCD – an additional safety feature for the installer and user. The possibility of mounting on a DIN rail facilitates integration with existing modular equipment.

Key features and benefits

• High impulse withstand current (5 kA) – ensures reliable protection in the event of sudden overvoltages.
• Short-circuit strength 10 kA – allows safe operation in installations exposed to high short-circuit currents.
• Wide range of wire cross-sections (1.5 - 35 mm²) – enables connection of wires of different thicknesses, adapting to the needs of a specific installation.
• Rated impulse withstand voltage 4 kV – increases resistance to atmospheric overvoltages and disturbances in the electrical network.
• Operating temperature from -25°C to 60°C – allows the switch to be used in various environmental conditions.
• Protection degree IP20 – provides protection against touching fingers and against the ingress of solid objects larger than 12.5 mm.
• Possibility of additional equipment - provides flexibility in adapting the switch to specific installation requirements.
• Compliance with safety standards - guarantees correct operation and safety of use.

This switch is not only a protective element, but also an investment in peace of mind and the safety of your family and property. Its reliability and precision of operation make it an ideal choice for both professional installers and demanding end users.
