4-pole 80A power source switch in enclosure, OBP enclosure with black knob PRZK-4080OBP/ PRZK-4080OBP\/

Power source switch – reliable switching between mains and emergency power

This four-pole power source switch with a rated current of 80A is a robust solution for emergency power systems, providing smooth and safe switching between the power grid and a generator. The device, designated as PRZK-4080OBP/, is designed for mounting on a TH35 rail and is characterized by high quality workmanship and durability.

Functionality and application

The PRZK-4080OBP/ switch allows you to select one of three operating modes: mains, off (position 0), and generator. The 4-pole (3P+N) design ensures disconnection of all phases and the neutral conductor, which is crucial in modern installations requiring complete galvanic isolation. This makes the device ideal for single-family homes, farms, small production plants, and anywhere reliable power is a priority. The switch is particularly useful in places where automatic switching to emergency power is required in the event of a voltage drop in the main network.

Design and mounting

The switch has been designed for easy mounting on a standard TH35 rail. A solid OBP housing provides protection against mechanical damage and external factors. Equipped with a black knob, it enables intuitive operation and unambiguous identification of the current switch status. The special design of the knob prevents opening the switchboard door in the on (I-ON) position, which increases safety. The device is made of environmentally friendly materials suitable for recycling. The cross-section of the wires connected to the switch is 6-25 mm².
