Product Description


Product Introduction 
DZ20 series moulded  case circuit breakers are suitable for AC 50hz, rated current from 16A to 630A, 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 Feature
This 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.
