A Circuit Breaker automatically switches off electrical circuit during abnormal condition of the network means in overload condition as well as faulty condition.
Maximum Input Current The instantaneous maximum output of SERVOPACK is approximately 3 times of the rated output for maximum for 3 seconds. Accordingly, select a molded-case circuit breaker whose breaking time is 5 seconds or more at 300% of SERVOPACK rated current. The general-purpose low-speed acting molded-case circuit breakers are applicable. The power supply capacity per SERVOPACK when using a servomotor is described in 2.5.2 Molded-case Circuit Breaker and Fuse Capacity. Select a molded-case circuit breaker with the capacity larger than the effective load current (when using more than multiple SERVOPACK) calculated from the total power supply capacity. The consumption of other controllers must be considered when selecting a molded-case circuit breaker (2) Inrush Current Refer to 2.5.2 Molded-case Circuit Breaker and Fuse Capacity for SERVOPACK inrush current. The allowable inrush current for a low-speed acting molded-case circuit breaker is approximately 10 times of the rated current for 0.02 seconds. When turning ON multiple SERVOPACK simultaneously, select a molded-case circuit breaker with the allowable current for 20 ms larger than the total inrush current shown in 2.5.2 Molded-case Circuit Breaker and Fuse Capacity.
Circuit breaker refers to the switching device that can close, carry and disconnect the current under normal circuit conditions, and can close, carry and disconnect the current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The division of high-voltage and low-voltage boundaries is relatively vague. Generally, those above 3KV are called high-voltage appliances. The circuit breaker can be used to distribute electric energy, start the asynchronous motor infrequently, and protect the power line and motor. When they have serious overload, short circuit, undervoltage and other faults, it can automatically cut off the circuit. Its function is equivalent to the combination of fuse switch and over and under heating relay. Moreover, it is generally not necessary to change the parts after breaking the fault current. At present, it has been widely used. Power distribution is an extremely important link in the generation, transmission and use of electricity. The distribution system includes transformers and various high and low voltage electrical equipment, and the low voltage circuit breaker is an electrical appliance with large amount and wide range of use. working principle The circuit breaker is generally composed of contact system, arc extinguishing system, operating mechanism, release, shell, etc. In case of short circuit, the magnetic field generated by large current (generally 10 to 12 times) overcomes the reaction spring, the release pulls the operating mechanism to act, and the switch trips instantaneously. In case of overload, the current increases, the calorific value intensifies, and the bimetallic sheet deforms to a certain extent to promote the action of the mechanism (the greater the current, the shorter the action time).
