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.
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.
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).
No Surge Protection Required
Special main contact materials minimize chopping current.
No surge suppressor/arrester is required except for special
applications.
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.
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 APPLICATION
OPERATING COIL EXCITATION
The current limiting fuses shall be combined for capacitor switching application.
Non-Latched

The series reactor shall be connected, especially back-to-back application.
Mainly applied to frequent switching operation such as motor.
Service life of capacitor switching
The switching, opening and closing, of capacitor produces severe condition for contactor, such as

require to be contact closed even by power loss.
The criteria of maximum number of capacitor switching are shown in the figure below. The vacuum interrupters should
be replaced when the number of switching operations reached to point shown in figure.
PROTECTION COORDINATION
The protection coordination with upper/lower stream relay shall be evaluated by considering total system and load
characteristics.

The single-phase protection shall be performed which may be occurred by power fuses.
APPLICATION GUIDE TO SURGE
No surge protection is required except for special application, however the insulation coordination shall be evaluated by following
table.

Notice
The surge suppressor shall be installed for machine rated at

on secondary circuit of transformer.
Capacitor
Not required
Refer to the clause for capacitor application.
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.
CONTROL TRANSFORMER
The contactor can be operated with following burden of control transformer.
