Since the introduction of the first Vacuum Interrupter in 1962, Toshiba has been continuously improving and developing Vacuum Technology. Over 3 millions 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.

Class NK certificate (Marine application)

Compact and Lightweight Compact and slim design contactors can be applied to either two-tier motor starters or slim starters per IEC 60470 (2000). The Contactors CV-6GA(L) and CV-6HA(L) have the same outline and mounting dimensions, as well as dual voltage ratings (3.6/7.2kV).

Low Power Consumption The control device adopts an electronic circuit, the control voltage either AC or DC can be easily changed by switches in the circuit board without changing the coil and/or other parts. Since the economizing resistors are eliminated, the power consumption in holding condition has been reduced.

Excellent Breaking Performance Since the higher interrupting capacity and short-time withstand capability, Toshiba Vacuum Contactors are appropriate to fuse combination for large capacity load, and to high-speed breaking. No Surge Protection Required Special main contact materials minimize chopping current. No surge suppressor/arrester is required except for special applications. Conformity to Industrial Standard Conforming to latest international standards such as IEC, BS, AS and JEM, being certified by class NK and TUV, Toshiba Vacuum Contactors can be used widely all over the world.

Capacitor trip device The capacitor trip device will be used for latched contactor when DC power source is not available. The device charges from AC power, and supplies DC power to the trip coil at trip command. The alarm contact is provided on CIT-10Q.

Surge suppressor The three phase type NV60K304T1 for 3.6/7.2kV and NVK95K304T1 for 12/15kV are available.

Mechanical interlock The mechanical interlock shall be used in the reversing starter to prevent mechanically from c l o sing the fo rward

The surge suppressor is composed of capacitor and series resistor, and is one of the most excellent protection mediums. The device features suppression as well as a decrease of surge generation. Particularly being free from limitation on the number of operating times, this device is suitable for protecting motors and transformer required performing frequent operations. The surge arrester has no effect of suppressing the surge generation, this suppresses overvoltage to within a fixed level.
