High Voltage Vacuum Circuit Breaker for Indoor

Model NO.: High Voltage Operation: Electric Type Arc-extinguishing Medium: Vacuum Structure: as Per Design or Customer Demand Type: Circuit Breaker Certification: ISO9001-2000, CCC Specification: CCC HS Code: 8535210000 Breaking Capacity: High Voltage Circuit Breakers Speed: High-Speed Circuit Breaker Installation: Fixed Poles Number: as Per Design or Customer Demand Function: Circuit-Breaker Failure Protection Trademark: Qikai, Or ODM/OEM as per customer demand Origin: Shandong, China QVBP Indoor High Voltage Vacuum Circuit Breaker Product Description:
QVBP-12/T 630-25 T1250-31.5 indoor high voltage Vacuum Circuit Breaker(Solid Seal type) is leading technology new generation circuit breakers.The circuit breaker is small sized solid seal vertical installation vacuum circuit breaker with own isolation switch. Vacuum interrupter and electric conduction terminal are encapsulated to polarity with expoxy resin by APG process,thus to improve machinery reliability, prevents risks of contamination and condensation between phases and insulation against ground. At the same time, it enhances the external insulation, improves the insulation level of the interrupter, and it make the vacuum circuit breakers smaller in size. Scope of application: This product can be widely used in three-phase AC 12KV,50HZ power systems in factories, residential areas, switching station, box-type substation and cable branch box,etc.It could be used to break down, closing the overload current, failure current for a variety of control and protection purposes, to meet the requirements of distribution automation.
