Low Voltage Thermal Magnetic Molded Case Circuit Breaker 400A 630A
KRIPAL has the Utility Model Patent for the structure of double making & double breaking!
The UKM32 series MCCB are used for making, breaking, and protection of low-voltage distribution systems and motors. Several breaking capacities exist for each model of circuit breaker, meeting
the demands for varying types of protection. Several different rated current levels are available for
each frame size
