Product Description
DW17
Application
1. DW17 series universal circuit breaker (Abbr circuit breaker) feature in compact conformation and size, light weight, featured series, good components interchangeability, perfect protection system, high technical economy standard, convenient maintenance and usage. The technical performance of circuit breaker conforms to IEC947-2 and GB14048.2-94. Standards. The circuit breaker is applicable to rated working voltage and current with 380V, 660V, 50Hz, which is mainly used for power distribution and infrequent changing over; And protection for the overload, under voltage and short circuit of circuit and electric equipment, also with the protection of classified choice. It can actuate the motor directly and protect the motor, generator and rectifier from the damage of overload, short circuit and under voltage, etc.
2. The typic connection types of circuit breaker. ( refer to diagram 1)
3. The classification and specification of circuit breaker (refer to table 1) NOTE: 1, Overload long-time delay release with fastener W1 or with fastener and signal W2, short circuit instantaneous release with fastener W3 or with fastener and signal W4; W1, W2, W3, W4 is just used for frame level 1, 2 and 3. And short circuit release is used for all series. If need, it can be indicated when ordering.
Electric operation is enclosed maintenance operation manual; Drawout type circuit breaker is enclosed the operation manual of position alteration and the expansion guidways of maintenance. The customer can order according to his need.
Blocking solenoid is mainly used for the protection of circuit breaker of motor.
2. Normal working condition
