DZ20 series plastic shell circuit breaker (hereinafter referred to as circuit breaker), its rated insulation voltage is 660V, AC 50Hz, rated working voltage 380V and below, and its rated current is from 32A to 1250A. Generally, it is used for power distribution, among which the rated current of type C is 160A and below, and the circuit breaker of type 630 and below shell frame can also be used as a protective motor. Under normal circumstances, the circuit breaker can be used for infrequent line conversion and infrequent start of the motor, respectively.
Number of poles: 3P
Rated operating voltage: 380
Rated insulation voltage: 660
Short-circuit breaking capacity** value: 50/0.25 32.5/0.25
Circuit breaker rated current: 800.1000.1250
Operation frequency (times/hour): 20
Shunt trip:
Rated control power supply voltage: AC220V, AC380V.
When the rated control supply voltage is between 70% and 110%, the shunt trip should reliably trip the circuit breaker.
Undervoltage Tripper:
Rated working voltage: AC220V, AC380V. When the voltage drops (or even slowly drops) to the range of 70%-35% of the rated voltage, the undervoltage tripper should act, and when it is lower than 35% of the rated voltage of the tripper, the undervoltage tripper should be able to prevent the circuit breaker from closing, and when the power supply voltage is equal to or greater than 85%, the circuit breaker should be able to be closed.
Alarm Contacts:
Rated working voltage: AC220V, agreed heating current: 3A.
Auxiliary contacts: Auxiliary contacts can be installed when undervoltage trippers and shunt trippers are worn in different fashions. The number of non-energized operation performance of the auxiliary contact is the same as that of the circuit breaker, and the number of power-on operation is 6050 times, and when the number of operation performance of the circuit breaker is less than 6050 times, it is equal to the circuit breaker.
