LMM1 MCCB 63-2500A

Moulded case circuit breaker (mccb) is a kind of automatic switch device. Its contact, arcing chamber, release and operating mechanism are all installed in the moulded case. It can automatically cut off the current when the current exceeds the setting value, and has the protection functions of overload, short circuit and undervoltage. Suitable for branch protection switch, widely used in residential, commercial construction, industrial production and other fields.
