3-pole +N power source switch (non-disconnectable) with knob on the disconnector PRZK-3080N\W02

Power source switch for demanding installations

This three-pole (3P+N) switch from SPAMEL, model PRZK-3080N\W02, is a reliable solution for switching between the mains and a generator. It allows for safe and manual selection of the power source, which is crucial in emergency power systems. Designed for DIN rail mounting, it can be used in both commercial and more demanding home installations.

Functionality and application

The PRZK-3080N\W02 switch allows you to select one of three positions: I (mains), 0 (off) and II (generator). This provides flexibility and control over energy supply. It is particularly useful where uninterrupted power supply is a priority – in workshops, small production plants or residential buildings with sensitive equipment. The switch design ensures that the neutral conductor (N) is not disconnected, which is important in TN-C systems.

Solid construction and parameters

The housing made of durable plastic ensures durability and resistance to mechanical damage. The switch is designed to operate with a rated current of 80A, making it suitable for high-power loads. Mounting on a TH35 rail guarantees stability and ease of installation. Solid terminals allow connection of wires with a cross-section of 6…25 mm², ensuring a safe electrical connection. The rated insulation voltage is 690V, and the impulse voltage 6kV – these parameters confirm the high quality and safety of use. Additionally, the ability to seal the switch with seals increases its reliability and prevents unauthorized changes to settings.
