Product Description

Moulded Case Circuit Breaker JCNSX250N125A MCCB Thermal magnetic Type from HUBEI JUCRO ElECTRIC

The molded case circuit breaker can automatically cut off the current when the current exceeds the jump setting.Plastic-case refers to the use of a plastic insulator as the housing of a device, used to isolate the conductors and the grounded metal parts.Plastic-case circuit breakers usually contain thermo-magnetic tripping units, while larger plastic-case circuit breakers are equipped with solid-state tripping sensors.The tripping unit is divided into: thermally magnetic tripping and electronic tripping device.
