▶
There is a variety of products and it is highly compatible. Its installation
period can be shortened.
▶
It is easy and convenient to operate using a high-performing and safe
circuit breaker.
It retains stable electrical and mechanical characteristics by adopting a Motor
Spring Drive or a Solenoid Method.
It maintains a long operational cycle through an excellent interruption of the
breaking part, a characteristic curve and a firm operating mechanism.
There is little degradation on the degree of vacuum and abrasion of contacts
when the vacuum breaking part is used for a long period of time, its breaking
capability is great and its mechanical cycle lasts for a long time.
▶
It is easy to expand the device and to perform maintenance through
various protection functions and safety.
It is structured in units by its function and purpose, so it is easy to plan for system
expansions.
CB and relay are draw-out types that enable an easy maintenance.
