4-pole 80A power source switch with knob on disconnector PRZK-4080\W02

Power source switch – reliable power change

This four-pole power source switch, with a rated current of 80A, is a key element of the installation guaranteeing continuous power supply. It allows quick and safe switching between the power grid and a generator, which is particularly important in places where power outages can cause serious losses. Made of durable plastic, designed for mounting on a TH35 rail.

Functionality and application

The PRZK-4080\W02 switch is a type I-0-II device, which means the ability to choose between three positions: power from the grid, load disconnection or power from the generator. The 4-pole (3P+N) construction provides complete separation of the phases and the neutral conductor, which increases safety and compatibility with modern installations. It will work both in single-family homes and in industrial facilities, workshops or small production plants.

Solid construction and electrical parameters

The switch has been designed with long-term and reliable operation in mind. It withstands short-circuit current up to 6kA and has high mechanical durability – up to 10,000 cycles and switching durability – up to 1500 cycles. The rated insulation voltage is 690V, and the impulse withstand voltage is 8kV. Connection cables with a cross-section from 10 to 25 mm² ensure a stable connection and minimize the risk of overheating. The device is resistant to vibrations, shocks and cyclic damp heat.

The switch is characterized by a high continuous rated current of 80A, which ensures safe operation even under heavy load. The rated insulation voltage at 690V guarantees safety in various installation conditions. It protects the installation against the effects of short circuits thanks to the rated short-circuit current of 6 kA. High mechanical durability – up to 10,000 cycles – ensures long-term operation of the device. It allows connection of cables with a cross-section from 10 to 25 mm², and the standard mounting on a TH35 rail facilitates integration with the existing switchboard.
