3-pole +N power source changeover switch (disconnectable) in ABS housing PRZK-4125N\OBA

Power source switch – reliable switching in your installation

This three-pole power switch (plus neutral) is a solid solution for safe and convenient switching between two power sources. The ABS housing construction ensures durability and resistance to mechanical damage, and the high rated current allows for use in demanding applications. The switch is complete, ready for installation, which translates to saving time and installation costs.

Functionality and application

The PRZK-4125N\OBA switch allows manual switching of the load between two independent power sources. This is particularly useful in situations where uninterrupted power is required – e.g. during a failure of one of the sources. Thanks to the "0" position (off), it provides additional safety during maintenance or repair of the installation. The possibility of indirect and panel mounting provides great flexibility in choosing the installation location.

• Purpose: Switching between two power sources in electrical installations.
• Applications:
  • Uninterruptible Power Supply (UPS) systems.
  • Generators.
  • Industrial machines and equipment.
  • Commercial and residential buildings requiring reliable power.

Key features and benefits

The switch design is designed with ease of installation and use in mind, as well as to ensure maximum safety:

• High current capacity: Rated continuous current of 125A allows connection of even demanding receivers.
• Durable housing: Made of plastic (ABS) provides resistance to mechanical damage and external factors. IP65 protection class guarantees protection against dust and water jet, which is important in harsh working conditions.
• Safety of use: The "0" position allows complete disconnection of the load during servicing or repair of the installation.
• Easy installation: The possibility of indirect and panel mounting facilitates integration of the switch with the existing electrical infrastructure. Screw connection of the main contacts ensures secure and durable electrical connections.
• Intuitive operation: The knob allows quick and convenient switching between power sources.
• No auxiliary contacts: The lack of auxiliary contacts simplifies the design and reduces the risk of failure, while fulfilling the basic functions of the power source switch.
