Introduction:
- The DC MCCB 125A manufactured by CNTN Electric utilizes highly flame-retardant materials to effectively isolate electric arcs, while also providing protection against dust, moisture, and electric shock.
- CNTN Electric is capable of manufacturing not only 125A DC molded-case circuit breakers in accordance with customer requirements, but also models ranging from 100A to 630A.
- Our DC Molded Case Circuit Breakers (MCCBs) are suitable for three-phase four-wire circuits, and can also be used in three-phase three-wire and three-phase two-wire circuits.
- CNTN Electric manufactures not only AC 100A 4-pole molded case circuit breakers, but also DC molded case circuit breakers.
- CNTN Electric manufactures not only molded-case circuit breakers with white housings made of phenolic resin, but also those with gray and black housings made of plastic.
- The DC molded-case circuit breakers manufactured by CNTN Electric feature robust environmental adaptability, making them flexibly suitable for a wide range of application scenarios.
