A load break switch ie. on load break switch (LBS) which is a capable small fault current breaking switchgear.
It is not like VCB or GCB which can even breaking short circuit current, Thus load break switch is actual a on load switching on/off switchgear at normal condition, normal application load break switch mechanical life and electrical life is not high required, So Mechanical is less than 5000 times, and electrical life is also less than 1000 times.
So, no load break switch is actual a disconnector switch.
Some special load break switch is capable to switching on/off capacitive load or inductive load and with higher life request.
we provide with different type of load break switch, like sf6 gas type, vacuum type and air type.
