Product Introduction Factory supply DZ20Y 380V 400V 3 phase 3P 100A 225A 400A 630A 1250A MOULDED CIRCUIT BREAKER MCCBDZ20 series moulded case circuit breakers are suitable for AC 50hz, rated current from 16A to 1250A, rated insulation voltage 660V, rated working voltage AC380V/400V and below circuits, this series of circuit breakers are generally used for power distribution, and can also be used to protect motors use. Under normal circumstances, the circuit breaker can be used for the infrequent switching of the line and the infrequent starting of the motor respectively.
Circuit breakers for distribution are used to distribute electrical energy in the distribution network and serve as overload, short-circuit and under-voltage protection for lines and power equipment.
The circuit breaker for protecting the motor is used in the power distribution network for the starting and running of the squirrel-cage motor, and for the overload, short-circuit and under-voltage protection of the squirrel-cage motor.Constructure FeatureDZ20-100/3300 3P 16A 20A 25A 32A 40A 50A 63A 80A 100A Electric Air Safety Molded Case Circuit Breaker MCCBThis series of circuit breakers is based on Y-type products and consists of four parts: insulating shell, operating mechanism, contact system and release. The operating mechanism of the circuit breaker has the function of quickly closing and breaking the contacts, and its 'close', 'open' and 'free trip' positions are distinguished by the handle position.
C-type and J-type circuit breakers are derived and designed on the basis of Y-type circuit breakers. The J-type circuit breaker is a structural improvement of the contacts of the Y-type circuit breaker, so that in the case of a short circuit, the contacts can be quickly disconnected before the action of the mechanism to achieve the purpose of improving the on-off capability.DZ20-400/3300 three phase 3 poles 250A 315A 350A 400A molded case circuit breaker MCCB
