TOMC7DC-63 1P DC MCB
The specifications of the TONGOU TOMC7DC-63 1P DC MCB miniature circuit breaker range from 12 volt dc to 250 volt dc.
The current specifications range from 1 amp to 6 amps for low current, 10 amps to 40 amps for medium current, and 50 amps to 63 amps for high current.
All comply with international IEC standards, and the products are usually suitable for photovoltaic solar power generation systems, fusion systems and storage systems.
In a set of solar combiner boxes, in addition to DC circuit breakers, DC fuses, DC surge protectors, and DC isolators are generally installed.
To avoid personal electric shock accidents, leakage protection switches will also be installed.
The function of DC MCBs is actually the same as that of ordinary MCBs.
There are short-circuit protection, overload protection and general circuit breaking function.
The main difference is that the DC MCBs use in direct current (DC), the direct current (DC) is a unidirectional flow of electric charge.
Direct current can flow through conductors such as wires, but it can also flow through semiconductors, insulators, or even vacuum like electron beams or ion beams.
The current flows in a constant direction, which is different from the curvilinear movement of alternating current (AC).
