WashiON KYORITSU KEIKI VHS Type High-Voltage Vacuum Contactor

Manufacturer: WashiON KYORITSU KEIKI
Model: VSH Type

Features

High reliability:
As a result of thorough quality control, the product maintains consistently high reliability.
Compact design:
In addition, it uses multi-purpose, tracking-resistant glass polyester molding insulation, providing a compact structure with excellent insulation reliability.
Maintenance-free:
Therefore, low arc voltage, quick insulation recovery, and long service life minimize the need for vacuum interrupter maintenance.
