The Difference Between Several DC Circuit Breakers

Aug 18, 2021

The DC circuit breaker adopts a special arc extinguishing and current limiting system, which can quickly break the fault current of the DC power distribution system and greatly improve the level difference coordination. The DC circuit breaker is especially aimed at accidents such as skipping and tripping between the test and protection screen and the power distribution screen in the DC system of power engineering. This series of DC circuit breakers has excellent performance and can avoid the above-mentioned faults. The level difference coordination characteristics of DC circuit breaker products are the best among similar products at home and abroad. It has super-first-class current-limiting performance, and can accurately protect relay protection and automatic devices from overload, short-circuit and other fault hazards. The DC circuit breaker has the advantages of current limiting and arc extinguishing capabilities. After a large number of comprehensive scientific experiments, it can achieve full selective protection among the main (sub) screen, protection screen, and relay screen in the DC system below 3000Ah.

TM1Z DC Molded Case Circuit Breaker

TM1Z DC molded case circuit breaker is a special circuit breaker for solar photovoltaic power generation developed by People's Electrical Appliances in order to meet the needs of the market. Its rated voltage is as high as DC1000V and current is as high as 1250A. The wiring method is the same as that of 2P products, which is more convenient for customers.

According to the operation mode, it can be divided into: direct operation of the main body: operation of the electric operating mechanism: operation of the rotary handle.

According to the form of protection, it can be divided into: line protection: line isolation.

According to the wiring form: front-board wiring; rear-board wiring; plug-in wiring; withdrawable wiring (shelf-level current Greater than or equal to 400A)

TX7-63Z DC miniature circuit breaker

The TX7-63Z series DC miniature circuit breaker is the same as the DC molded case circuit breaker. It is also a professional circuit breaker for solar photovoltaic power generation.
