Test switches and accessories

Test switches are designed and manufactured to allow quick and easy multi-circuit testing of switchboard relays, meters and instruments by any conventional system.

These test switches and related test plugs have the features necessary for applications involving the measurement of individual currents and voltages associated with substation instrumentation and protection devices. They have been especially designed for the measurement of potential elements, current elements, and make-before-break short-circuit elements related to Current Transformer (CT) circuits.

Why ABB?

  • Possible to test components and circuits without disconnecting existing wiring
  • Standard screw type terminals (optionally stud and nut)
  • Secure testing with good isolation between the terminals
