One-Touch TB

A tool to produce simultaneous short circuits on the external connection terminal blocks (TB) during withstanding voltage tests on various types of panels (electricity distribution - monitoring - operation - control).
In case of conventional withstanding voltage tests, for hundreds of points in the external connection terminal blocks, each screw must be loosened for winding, or short circuit bars have to be used. The conventional method is cumbersome and time-consuming. It calls for several hours to prepare a withstanding voltage test lasting only one minute.
"One-Touch TB", short circuit plate for terminal blocks provides a simultaneous short circuit 40-50 terminal pins. The preparation time is reduced to less than 1/5 of the current time (compared with previous results of our company), resulting in a considerable reduction in costs and simplifying the short circuiting procedure.

  • Easy & Accurate, Multipoint terminal block short-circuit is made with ONE TOUCH!
  • Easy connection of short circuit plates
  • Simple structure at low costs
  • Use of SUS for a rust-free environment
  • Spring plate type eliminates connection failures
