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

Power source switch – reliable power switching in every installation

This 4-pole power source switch with a current of 80A is a solid solution for switching between the grid and a generator. Manufactured by the renowned company Spamel, it ensures safety and reliable operation in demanding conditions. It is ideal for both home and industrial installations where a reliable change of power source is required.

PRZK switches are based on proven RSI disconnectors, inheriting all their advantages. The construction based on combining two RSI disconnectors into a single unit, using a common cover, guarantees high rigidity and stability of the system. This translates into long-lasting and trouble-free operation of the device.

Functionality and application

The switch allows you to choose between three positions: I (grid), 0 (off) and II (generator), making it a versatile tool in emergency power systems. The 4-pole design (3P+N) provides complete galvanic isolation, which is particularly important in modern installations. The possibility of mounting on a TH35 rail facilitates integration with existing switchboards.

• Purpose: Switching the power source between the grid and a generator.
• Application: Single-family homes, farms, small production plants, emergency power systems.
• Mounting: On a TH35 (DIN) rail, which facilitates installation and replacement.
• Durability: Designed to work with wires with a cross-section of 6-25 mm².
• Protection: IP65 protection class provides resistance to dust and moisture on the front side.

Construction and characteristic features

The PRZK switch is distinguished by a solid mechanical construction and high-quality silver-plated contacts, which guarantee a reliable electrical connection. The control knob has been designed to prevent the switchboard door from being opened in the on position (I-ON), increasing safety. Additionally, the possibility of emergency opening of the switchboard door in the closed disconnector state provides additional protection. The device is made of environmentally friendly materials and is recyclable.

• Execution W02 – standard switch execution
• High current strength – 80A rated continuous current
• Safety – door opening lock in the on position
• Durability – silver-plated contacts ensure a reliable connection
• Ecology – materials suitable for recycling
