Air Circuit Breaker
Air Circuit Breaker
(1)This type of circuit breaker usually has a steel frame, and all components are installed inside the frame. It has a large capacity and can be equipped with multiple functional releases and more auxiliary contacts. It has high segmentation ability and thermal stability, so it is commonly used in places that require high breaking capacity and selective protection.
High quality air circuit breaker ACB MTW1 3P/4P 1000A-6300A and motor overload and short circuit protection fixed and drawer
W1 series intelligent breaker is applicable for distribution network of AC 50Hz, rated voltage of 400V and 690V, and rated current of 630A～6300A, to distribute electric energy and prevent the circuit and power equipments from harm of overload, under-voltage, short circuit and single-phase earth etc.Provided with intelligent protecting function and precise selective protection, breaker can enhance the dependability of power supply and avoid unwanted power cut. This product accords with the standard of GB14048. 2 " low-voltage switchgear and controlling equipment,the low-voltage circuit breaker" and IEC60947-2 "low-voltage switchgear and controlling equipment the second part: low-voltage circuit breaker ".
