KYN28A-12 and KYN61 high voltage switchgear components!
The Indoor high voltage isolation switch GN30-12 is new design for rotating contact type switch , there have insulators and contacts .
The isolation switch has no arc extinguishing device, although the
rules stipulate that it can be operated in cases where the load
current is less than 5A, but it is generally not load-bearing. But
the isolation switch structure is simple, it can be seen at first
glance from the appearance of the state of operation, when
overhauling obviously break point.
The circuit breaker is referred to as "switch" in use, and the
isolation switch is referred to as "switch" in use.
