ZN28A-10 Indoor Vacuum Circuit Breaker

Product Overview

This series of high-voltage vacuum circuit breakers is suitable for power systems and industrial and mining enterprises, providing control and protection for 3-phase AC 50Hz, 12kV power supply and distribution systems, as well as frequent operation environments. It features fast recovery of dielectric strength, high insulation strength, low arc energy and electrical corrosion rate, long service life, minimal maintenance, non-explosive, non-polluting, low noise, and strong adaptability.

This series of vacuum circuit breakers is compatible with fixed switchgear models XGN-10(Z) and GG-1A(F)Z. They can be equipped with either the CD17 electromagnetic actuator or the CT19 spring actuator, and can replace the soon-to-be phased-out oil circuit breakers in oil-free transformation without any modifications, offering low investment, easy installation, and time-saving.
