Working Mechanism

  • These switches have centre-off, source A and source B positions.
  • Both sources are cut off from the load when the switch is in the centre-off position.
  • Source A is connected to the load and Source B is disconnected when the switch is in the source A position.
  • Source A is disconnected and source B is connected to the load when the switch is in the source B position.

Features

  • Eaton heavy duty double throw safety switches have two interlocked switches with a common connection to transfer service from a primary power source to a backup power source.
  • Their stack-switch design with fusible units reduces wall space requirements.
  • These three-pole switches include a palm-fitting visible red handle, a tri-lingual nameplate and an embossed red On / Off indicator.
  • They have NEMA-rated enclosures for protection from contamination.

Standards and Approvals

  • UL

Frequently Asked Questions

What is the benefit of interlock in switches?

The interlock ensures that the two switches cannot be closed at the same time, preventing them from being operated in parallel.

How do I select the right Eaton heavy-duty double throw switch for my application?

Selecting the right Eaton heavy-duty double throw switch depends on factors like the voltage & current rating of the power sources and load, the type of power being used (AC or DC) and the specific requirements of the application.

How to maintain Eaton heavy-duty double throw switches?

Eaton heavy-duty double throw switches require periodic inspection and cleaning to ensure proper operation.
