12kv vacuum circuit breaker for sale online, it is suitable for indoor use. Rated current is 630A, 1250A, 2000A, 2500A. VCB circuit breaker adopts the modular spring operating mechanism, with simple structure and stable performance.

Features:

Ultra-low-resistance type vacuum interruption meets the requirements of temperature rise of large current type, and lowers the energy loss.
Ideal contact material and shape, ensuring low current carrying value and stable contact resistance.
Integrated design of main conductive circuit made of compound isolation material and operating mechanism.
12kV vcb with few components and parts, compact and logical structure, assuring more reliable and safer operation.
12kV vacuum circuit breaker adopts the composite insulation structure, with high insulation level,no pollution or explosion danger.
Compact design enables the breaker to be installed within almost all switchgears.
Superior cost performance, vacuum circuit breaker is the ideal choice for engineering programs.

Tips: What are the reasons for choosing RDDLZ vacuum circuit breaker?

RDDLZ 12kV vacuum circuit creaker has the reliable interlocking function. Designed into fore and rear separate structure, it is used as the unit for fixed installation, in addition, it can be assembled with the chassis, as the individual handcart.
Employing the mature APG technique and advanced epoxy-resin solid encapsulation technology, the vacuum arc-extinguishing chamber, main conductive circuit, insulating support, etc. are combined organically to form a integrated solid-encapsulated pole, the surface of vacuum arc-extinguishing chamber is not affected with the environment, so as to really realize the maintenance free.
