4-pole power source changeover switch 160 A with knob on the disconnector PRZK-4160\W02

Power source switch – reliable power switching

This four-pole power source switch PRZK-4160\W02 from SPAMEL is a solid solution for ensuring continuity of power supply in electrical installations. Designed to switch between two sources – mains and generator – it guarantees safe and efficient system operation. It is ideal for both single-family homes and industrial facilities, where power outages can cause significant losses.

Construction and application

The PRZK-4160\W02 switch is based on proven RSI disconnectors, which translates to high quality and reliable operation. The design combines two RSI disconnectors into a single unit, providing rigidity and confidence in operation. The device is particularly useful where switching between different types of power supply is required, e.g. mains and generator. Thanks to the presence of the "0" position, it is possible to completely disconnect both power sources, which increases safety during maintenance work. Mounting is done with screws, ensuring a stable connection of wires with a cross-section of up to 70 mm².

Key features and benefits

• High reliability: Construction based on proven RSI disconnectors guarantees long-lasting and trouble-free operation.
• Safety of use: The presence of the "0" position allows complete disconnection of both power sources during maintenance or failure.
• Versatility: Designed for three-phase installations with a neutral wire and for indirect mounting in switchboards.
• Durability: Rated continuous current of 160A allows servicing installations with high energy demand.
• Simple operation: Ergonomic knob facilitates quick and intuitive switching between power sources.
• Protection against external factors: IP65 protection degree (front part) provides resistance to dust and moisture inside the switchboard housing.
• Durable connections: Screw connection ensures a secure and stable connection of large diameter wires.

Technical parameters in practice

The PRZK-4160\W02 switch has been designed to meet the requirements of even the most demanding electrical installations. Its parameters, such as the rated continuous current of 160A and the rated insulation voltage of 690V, guarantee safe and efficient system operation. In addition, the possibility of indirect mounting and high mechanical durability (20,000 cycles) make it an ideal choice for professionals and users who value quality and reliability. The IP65 protection degree protects against accidental contact with conductive elements inside the switchboard, increasing safety of use.
