Product Information

VK12s-12P sealed pole type indoor high voltage vacuum circuit breaker. The main design concept is: the main circuit adopts fixed pole to improve the environmental adaptability and insulation reliability of the circuit breaker; Improve the mechanism design, extend the service life of machinery and improve the reliability of machinery. Reliable mechanical and electrical performance, extended mechanical and electrical life.

VK12s-12P circuit breaker is an indoor switchgear with rated voltage of 12kV and AC 50Hz. The product meets the provisions of GB1984-2014, DL403-2000, IEC62271-100 and other relevant standards, and its performance reaches the level of M2-E2-C2.

VK12s-12P circuit breaker can be equipped with special propulsion mechanism to form a handcart type unit, and can also be used for fixed installation unit. The circuit breaker is equipped with reliable interlocking unit, which can meet the "five prevention" protection function of the switchgear.
It also has the following advantages:
1.Superior mechanism performance makes the mechanical life of the circuit breaker up to 20000 times (the data comes from the inspection (Experiment) report of the national electrical product quality supervision and Inspection Center (no:19K2235-S))
2.Passing the type test of the authority, breaking the short-circuit current for 50 times at full capacity
3.The DC component of the rated short-circuit current can be disconnected up to 57%
4.Pass the temperature rise test of 1.1 times the rated current
5.Strong environmental tolerance
6.Good interchangeability
7.Excellent corrosion resistance
8.Stable performance
9.It has passed the type test verification of the authority
10.Excellent comprehensive performance
