Description
Molded case breakers adopts internationally advanced design and manufacturing technology. According to the rated ultimate short-circuit breaking capacity (Icu), it can be divided into L-type (standard type) and M-type (higher type).
With its compact design, high breaking capacity, short arc distance, and strong vibration resistance, the KM1 series molded case breakers provide reliable performance in a wide range of land and marine applications.
Suitable for AC 50Hz distribution systems, with a rated insulation voltage of 800V (KM1-63:500V), a rated working voltage of 690V (KMI-63:400V), and a rated current of up to 1600A. The circuit breaker ensures reliable overload, short circuit, and under voltage protection, and can also be used for motor protection during infrequent starting.
KM1 series supports both vertical and horizontal installation.
