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
