Since the introduction of the first Vacuum Interrupter in 1962, Toshiba has been continuously improving and developing Vacuum Technology.

Over 3 million Vacuum interrupters have been produced for various types of vacuum apparatus such as contactors, circuit breakers and switches which are now widely used as result of their outstanding performance.

Toshiba has become a leading Japanese manufacturer that has attained a record exceeding 230 thousands Low and high voltage Vacuum Contactors produced.

Consistent with its dedication to the most advanced vacuum technology, Toshiba offers new series of High-voltage vacuum contactors.

By adopting an electronics controlled circuit and being designed compactly to ensure reliability, handling ease and safety, the new series of High-voltage Vacuum Contactors are suitable for Motor starters, Transformer feeders and Capacitor switching applications

Product Overview

  • Insulation recovery characteristics in vacuum are fast and arc time is short so wear on main contacts is low and service life is long.
  • Compact and lightweight operating mechanism with new vacuum interrupters.
  • CV vacuum contactor has acquired NK and TUV certification.
  • For most loads, surge protectors, like surge suppressors, are not needed because a low-surge contact material is used.
  • Applicable ratings: 7.2 kV – 12 kV, 200 – 720 A
  • Electric performance and mechanical construction that complies with JEM-1167(1990), IEC 60470(2000).
  • Quality control system is integrated from design to production and testing.
  • Circuit breaker uses high-reliability vacuum valve.
  • Operating mechanism is low-fault factor mechanism mounted on the lower front for long service life and easy maintenance inspections.
  • No environmentally dangerous materials are used.
  • Low noise when current is stopped.
