Residual current circuit breaker PFIM PFIM-100/4/003-A 102829

Residual Current Circuit Breaker (RCCB) PFIM-100/4/003-A is a reliable protection for electrical installations, designed for both home and commercial use. The device effectively protects against electric shock, as well as against the effects of short circuits and overloads. With a rated current of 100A and a four-pole design, the circuit breaker is perfect for circuits with higher power demand.

Functionality and application

The PFIM-100/4/003-A circuit breaker is characterized by high sensitivity to leakage currents (30 mA – type A), which ensures a quick response in the event of insulation failure. DIN rail mounting simplifies installation and integration with existing electrical infrastructure. Application in installations with a voltage of 400V and a frequency of 50Hz guarantees compatibility with most electrical networks. The short-circuit strength at the level of 10kA ensures resistance to sudden current surges, which translates into long-term and trouble-free operation.

Installation comfort and additional possibilities

The design of the circuit breaker has been carefully thought out in terms of ease of installation and subsequent operation. Lift and screw terminals, available from both the top and bottom, significantly speed up the connection of wires with a cross-section from 1.5 mm² to 35 mm². Additionally, the possibility of adding auxiliary contacts, undervoltage releases and a reclosing module expands the functionality of the device, adapting it to the specific needs of the installation. The power supply direction is arbitrary, which provides flexibility during installation. The optical contact position indicator facilitates visual control of the device status. A width of 4 modules allows for efficient use of space in the switchgear cabinet.

• Protection against electric shock thanks to high sensitivity (type A).
• Wide range of wire cross-sections – from 1.5 mm² to 35 mm² – ensures compatibility with various types of installations.
• Possibility of expanding functionality by adding auxiliary contacts and other modules.
• Solid construction and high short-circuit strength (10kA) guarantee reliable operation.
• Lock preventing accidental switching on of the circuit breaker after switching off due to a fault.
• Ambient temperature in operating conditions from -25°C to 60°C enables operation in difficult environmental conditions.
• Degree of protection IP20 provides basic protection against contact and solid bodies.
