TONGOU provides high-quality DC miniature circuit breaker(DC MCB). DC MCB has super first-class current limiting performance, which can accurately protect relay protection and automatic device from overload, short circuit and other fault hazards. DC has the advantages of current limiting and arc extinguishing capability. After a large number of comprehensive scientific tests, the full selective protection between main (sub) screen, protection screen and relay screen in the DC system below 3000ah can be realized.
DC adopts special arc extinguishing and current limiting system, which can quickly break the fault current of the DC distribution system and greatly improve the differential coordination. The series of DC have excellent performance and can avoid the above-mentioned faults, especially for the override trip between the test protection panel and the distribution panel in the DC system of power engineering. DC MCB products have the best level matching characteristics of similar products at home and abroad.
TONGOU always adheres to the principle of “quality first”, adheres to management informatization, production automation continuously improves production process quality and production management level.
