Susol vacuum contactors are used for switching motors, transformers and capacitors located on AC power lines.
Susol vacuum contactors are used for switching motors, transformers and capacitors located on AC power lines. It can be installed in multi-platform cells.
VCBS adopt the method of fast automatic power-off again. It provides more convenience and safety by providing high-speed downtime (3 cycles) with a wide range of accessories.
Tri-MEC vacuum contactors are used for switching motors, transformers and capacitors on AC power lines. They can also be installed in multi-platform cells.
A vacuum contactor includes a variety of mechanisms, including a vacuum breaker, a magnetic actuator, a high-strength molded front cover, and auxiliary devices. Vacuum cutters made of high alumina ceramic tube work stably at high temperature and with high working accuracy.

Characteristics:
Vacuum contactors provide versatile auxiliary functions with high strength and switching capacity. We have high and sustainable technology that no one can keep up with in this regard.
We provide high performance, high reliability and long service life.
Superior mechanical strength and degassing.
Due to the use of high alumina ceramic tube and high temperature degassing, it provides a long service life and is suitable for frequent use.
Short arc time.
Vacuum insulation has the property of rapid recovery.
When opening, the ability to break the current at the first available zero point to minimize wear of the contacts.
Reliable fault interruption
The current-limiting power fuse is able to protect devices and systems from breakdown current by disconnecting them in half a cycle.
Security:
Vacuum contactors provide a variety of auxiliary functions for safe and convenient operation.
