Safety
VTL3 series fixed lateral type vacuum circuit breaker has perfect mechanical and electrical interlocking
device. It has high operation reliability and long service life. Used with relevant switchgears, it can offer
safe power distribution function to ensure the safety of the operators and equipments.
Operating mechanism:
Modularized operating mechanism is another feature of VTL3. The operating mechanism is
located in the chassis which is in front of vacuum interrupter. It is convenient to maintain and
rapid to replace.
Poles:
We can supply three kinds of poles for VTL3 series lateral vacuum circuit breakers. They are
embedded poles, assembly poles type 1 and assembly poles type2.
