Youbian durable 40.5kV switch recloser is suitable for 50Hz, 40.5KV AC three-phase power systems, used for breaking and closing load currents, overload currents, and short-circuit currents. It adopts vacuum breaking technology, with a protection level of IP55, and is a basic standard automatic reclosing circuit breaker.

Youbian believes that selecting appropriate 33kV vacuum circuit breakers for different voltage distribution is crucial for the stability and safety of the power grid. At this voltage level, the equipment must be able to effectively cope with high electrical stress and quickly extinguish the arc in the event of a fault. Although various technologies exist, modern power infrastructure mainly relies on vacuum circuit breakers (VCBs) and SF6 gas circuit breakers because of their excellent performance and low maintenance requirements.

Youbian's durable 24kV vacuum circuit breaker is a medium voltage switchgear that uses vacuum arc extinguishing technology to interrupt load current and fault current. The working voltage range of 24kV VCB is 12-24kV, and it is widely used in the global power system due to its compatibility with medium voltage distribution networks, industrial substations, and renewable energy facilities. This device has reliable circuit breaking performance, long mechanical life, and safe switch operation, and avoids environmental problems caused by SF6 gas.

The 3 phase vacuum circuit breaker produced by Youbian in China is a device used for indoor switchgear installation. If there are special installation requirements, please contact our design team. The medium voltage vacuum circuit breaker adopts a lateral operating mechanism, suitable for indoor installation, and adopts a polarizing structure technology. Each pole is equipped with a vacuum arc extinguishing chamber, which is wrapped in resin through a special manufacturing process during the molding process. This structural approach can effectively protect the vacuum arc extinguishing chamber from the effects of impact, contamination, and condensation.
