circuit breaker pattern
We offer high-quality DC miniature circuit breakers (DC MCB). The current limiting performance of a DC MCB is first-class, allowing it to accurately protect relay protection and automatic devices from overload, short circuit, and other fault dangers.
Current limiting and arc extinguishing are two advantages of DC. The entire selective protection between the main (sub) screen, protection screen, and relay screen in the DC system below 3000ah may be realized after a significant number of extensive scientific testing.
We always follow the idea of “quality first,” implementing management informatization and production automation to continuously improve the quality of the manufacturing process and the degree of production management.
DC circuit breaker uses a unique arc extinguishing and current limiting mechanism that can swiftly break the DC distribution system’s fault current and considerably improve differential coordination.
The DC circuit breaker series of power engineering have good performance and can avoid the aforementioned errors, particularly for the override trip between the test protection panel and the distribution panel in the DC system.
In comparison to similar products both at home and abroad, DC MCB devices have the best level matching qualities.

TOMC7DC-63 1P DC MCB
TONGOU’s TOMC7DC-63 6-63A 1P DC MCB can provide protection against module for a variety of applications.
General
- The TONGOU TOMC7DC-63 1P MCB for dc circuits micro circuit breaker’s parameters span from 12 to 250 volts dc. Low current parameters range from 1 amp to 6 amps, medium current from 10 amps to 40 amps, and high current from 50 amps to 63 amps.
- Leakage protection switches will also be added to prevent personal electric shock mishaps.
- The function of a 1P DC circuit breaker MCB is identical to that of a regular MCB.
- All of the devices meet worldwide IEC standards, and they are typically used in photovoltaic solar power generating, fusion, and storage systems.
- In addition to DC circuit breakers, DC fuses, DC surge protectors, and DC isolators are commonly added in a series of solar combiner boxes.
- Short-circuit protection, overload protection, and general circuit breaker functions are all available.
- The primary distinction is that DC MCBs are used in direct current (DC), which is a one-way flow of electric charge.
- Direct current can flow through conductors like wires, as well as semiconductors, insulators, and even vacuum, such as electron or ion beams.
- The current flows in a straight line, unlike alternating current, which moves in a curved pattern (AC).
DC 63A 2P TONGOU’s MCB TOMC7-63DC has a nice look, is tiny in size, light in weight, has a high breaking capacity, and is quick to trip.
General
- Under normal circuit conditions, the 63A 2P DC MCB TOMC7-63DC may connect, carry, and break the current.
- It’s a mechanical switching mechanism that can be turned on, held on for a set period of time, or automatically disconnected in the event of a short circuit (such as short-circuit current).
- To improve current limiting capabilities, DC 2P 63A MCB TOMC7-63DC can be cascaded.
