3-pole +N 80 A power source switch in enclosure, OBP enclosure with black knob PRZK-3080NOBP\/

Power source switch – reliability and safety in one device

The PRZK-3080NOBP switch is a solid switching device designed for safely switching power between the mains and a backup source (e.g., a generator). With a rated current of 80A and three poles (3P) plus a neutral pole (N), the device ensures uninterrupted power supply in the event of a mains failure, protecting connected devices from uncontrolled voltage drops. The design with an inseparable neutral pole (N) makes it an ideal solution for three-phase installations where stability and safety are required.

Functionality and application

This switch allows manual switching to the emergency power source in emergency situations. It has a clear "0" position, which allows complete disconnection of the circuit before switching, minimizing the risk of short circuit or damage to connected devices. Mounting on a TH35 rail makes it easy to integrate with an existing distribution board. This is particularly important in facilities with high power demand, such as workshops, small production plants or larger single-family homes.

Construction and installation

Manufactured by the renowned Spółdzielnia Inwalidów "Spamel", the switch is characterized by a solid construction and high quality workmanship. Screw connections of the main circuit guarantee a secure and durable contact, and the possibility of sealing provides additional protection against unauthorized access. Compact dimensions allow for easy installation in a limited space of the distribution board. The switch is adapted for indirect mounting and in switchboards.
