Newark stocks a wide selection of switch disconnectors, providing a reliable method for isolating electrical circuits during maintenance and emergency situations. Our range includes options with different current and voltage ratings, ensuring compatibility with diverse industrial and commercial setups.

Switch disconnectors are manually operated devices that open or close an electrical circuit. They provide a physical gap between the contacts to ensure complete disconnection, enhancing safety during maintenance and repair.

Applications:

  • Industrial Plants: Isolating machinery for maintenance.
  • Renewable Energy: Disconnecting solar inverters and batteries.
  • HVAC Systems: Ensuring safe repair of heating and cooling units.
