Frequently Asked Questions

What is the capacity of these top / bottom feed safety switches?

These switches are capable of making 6X and breaking 12X overload currents.

What is the difference between a QA and CBC switch?

Pringle CBC switches are closed with the handle and open by pushing the red button on the trim plate or by an electrical trip, whereas Pringle QA switches are closed and open with the handle.

How does a phase relay work?

  • A phase failure relay may have one or more relay outputs, all of which are typically set up in a failsafe manner.
  • When the supply circumstances fall within the permitted tolerances, these relays activate, thereby closing the circuit.
