W2-1600 Series ACB Intelligent Air Circuit Breaker

Purpose and scope of use

The W2-1600 Series intelligent air circuit breaker(hereinafter referred to as circuit breaker)is suitable for distribution

networks with frequency of AC 50Hz,rated working voltage up to 690Vand rated current ranging from 200Ato 1600A. It's used to distribute electrical energy and protect lines and powerequipment from overload,short circuit,undervoltage, single-phase grounding(leakage)and otherfaults.The circuit breakerhas intelligent protection function and precise selective  protection,canimprovepowersupply reliabilityandavoidunnecessary poweroutages.Meanwhile,ithasopen type communication interface,which is convenient for fieldbus connection,and can be used for four remote operations to meet the requirements of the control center and automation system.Equipped with corresponding leakage transformerand intelligent controller,  leakage protection can be achieved.

The circuit breaker has isolation function and is represented by symbol“—1×”

The circuit breaker with rated working current of 630A and below can also be used foroverload,short circuit,phase loss,   undervoltage and ground protection ofmotorinAC50(60)Hz,400V distribution network.Undernormal condition,the circuit breaker can also serve forinfrequent switching of circuit and infrequent starting of motor.

The circuit breaker complies with GB14048.1-2012 Low-voltage switchgear and controlgear-Part1:General rules;And GB 14048.2-2008Low-voltage switchgear and controlgear-Part2:Circuit breakers;GB14048.4-2020 Low-voltage switchgearand controlgear-Part4-1:Contactors and motor-starters-Electromechanicalcontactorsand motor-starters(Includingmotorprotector)
