Residual current circuit breaker (RCCB) PFIM PFIM-100/4/003 102823

Residual Current Circuit Breaker – Protection and Safety of Installations

The residual current circuit breaker PFIM-100/4/003 is a key element ensuring safety in every electrical installation. The device is designed to protect people from electric shock and to protect the installation from the effects of short circuits and overloads. Thanks to its parameters, this breaker is perfect for both residential and commercial buildings.

Characteristics and Application

The PFIM-100/4/003 breaker is a four-pole device with a rated current of 100A and a short-circuit breaking capacity of 10kA. Its construction based on AC characteristics provides effective protection against leakage currents, and the mechanical lock prevents accidental switching on after a trip caused by a fault. The use of lift and screw terminals facilitates the installation and connection of wires with a cross-section from 1.5 mm² to 35 mm². The possibility of adding auxiliary contacts, undervoltage releases and auto-reclosing devices expands the functionality of the device, adapting it to the specific needs of the installation.

Key Advantages and Product Features

• High Reliability: The breaker is characterized by high quality workmanship and meets stringent safety standards.
• Versatility: The possibility of mounting on a DIN rail and a wide range of wire cross-sections make the device compatible with various types of installations.
• Flexibility: The ability to expand with additional functions (auxiliary contacts, undervoltage releases) allows you to tailor the breaker to individual needs.
• Easy Installation: Lift and screw terminals facilitate quick and easy connection of wires.
• Wide Voltage Range: Suitable for operation in networks with a voltage of 400V.
• Overload and Short Circuit Protection: Provides effective protection of the electrical circuit against dangerous situations.
• Any Power Supply Direction: Allows flexible adaptation to installation conditions.
• Optical Contact Setting Indicator: Allows for quick visual control of the device status.

Additional information: The breaker has a rated impulse withstand voltage of 4kV and an impulse withstand current of 0.25kA, confirming its high quality and durability. The ambient temperature in operating conditions is in the range of -25°C to 60°C, and the IP20 protection degree provides protection against finger contact. Power losses are 18.8W at a frequency of 50Hz.
