Magnetic contactor developed for power supply switching in a high voltage circuit

This contactor employs an electro-mechanical interlock system, which enables safe and secure high voltage power supply switching free from malfunction.
With a power supply device embedded, the contactor’s structure saves you from troubles.
The smallest size (C model) in the industry contributes to downsizing the unit.
 
●Rated voltage： 7.2kV Rated current： 200 - 2000A
　Rated voltage: 13.8kV Rated current: 600 - 1200A
　Rated voltage: 24kV Rated current: 630A

High voltage magnetic contactor employing vacuum valves

Compact type of our Model VSK. We successfully downsized the high voltage power supply switch Model VSK (7.2kV, 400A / 600A), and named VSK-C.
The smallest size in the industry contributes to downsizing the unit.
 
[Fixed Type]
●VSK6H40C (7.2kV 400A 31.5kA) ●VSK6H60C (7.2kV 600A 31.5kA)

[Draw-out Type]
●VSKO6H40C (7.2kV 400A 31.5kA) 　●VSKO6H60C(7.2kV 600A 31.5kA)

[Operating Voltage]
●100/110VDC、100/110VAC

compatible with thin cubicles

We made our Model VSK vertical and compatible with thin cubicles (700 mm in depth). Its draw-out design makes maintenance checks easy.
 
●Rated voltage： 7.2kV　 Rated current： 400A - 600A
●Operating voltage:100/110VDC、100/110VAC

High voltage and unipolar magnetic contactor

We have sold many units of this product for electric furnaces. This product is also suited to power factor improvements of synchronous condensers.
Only Kyoritsu Keiki manufactures and sells high voltage and unipolar magnetic contactors in Japan.
It is also suitable as a successor to Mitsubishi Electric’s models 3VC-1 and 6VC-2.
 
● Rated voltage: 3.3 – 6.6kV　Rated current: 300 – 400A
