| Abstract: | Introduction was made to HSM3-315 moulded case circuit-breakers which were an improvement design from HSM1-250 moulded case circuit-breakers by capacity rise. Analysis was made to the main factors which affected power distribution and protection functions of circuit-breakers. By an improvement in dynamic and static contacts and electromagnetic system, the temperature rise was lowered and the protection features were maintained. Via verification for the improved circuit-breakers, HSM1-250 moulded case circuit-breakers capacity rise from 250 A to 315 A has been realized. |
