4-pole residual current circuit breaker PFIM-40/4/003-MW 235410

Safety and reliability in your electrical installation

Residual Current Device (RCD) PFIM-40/4/003-MW is a key element ensuring the protection of people and equipment in electrical installations. The four-pole switch with a rated current of 40A and a sensitivity of 0.03A (AC) effectively reacts to leakage currents, minimizing the risk of electric shock and preventing equipment damage. Its short-circuit strength of 10kA guarantees reliable operation even in the event of serious disturbances in the network.

Installation and functionality for professionals

Mounting on a DIN rail is quick and intuitive, and the compact dimensions (width 4 modules, depth 70.5 mm) allow for optimal use of space in the switchgear cabinet. The switch has lift and busbar terminals from above and below, making it easy to connect wires with a cross-section from 1.5 to 35 mm² (solid) or from 1.5 to 16 mm² (stranded). 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, and the optical contact setting indicator makes it easy to check the device status.

Universal application and compliance with standards

The PFIM-40/4/003-MW switch is used in electrical installations in residential, commercial and industrial buildings. It meets safety standards, and its high quality of workmanship ensures long-lasting and trouble-free operation over a wide range of ambient temperatures (-25°C to +60°C). The device is characterized by high impulse withstand voltage and provides protection against the effects of short circuits and overloads. It has a degree of protection IP20, which protects against finger contact. Additionally, the device has a lock preventing accidental operation after switching off, and its power losses are 13.1 W at a frequency of 50 Hz.
