Short Description:

The W2-1 600 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 690V and rated current ranging from 200Ato 1600A.  It’s used to distribute

electrical energy and protect lines and power equipment from overload, short circuit,

undervoltage single-phase grounding(leakage) and other faults.  The circuit breaker

has intelligent protection function and precise selective protection, can improve

powersupplyreliabilityand avoid unnecessary power outages.  Meanwhile, ithas open

typecommunication 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 transformer and intelligent

controller, leakage protection can be achieved.

The circuit breaker with rated working current of 630A and below can also be used for

overload, short circuit, phase loss, undervoltage and ground protection of motor in AC

50 (60) Hz, 400V distribution network. Under normal condition, the circuit breaker can

also serve for infrequent switching of circuit and infrequent starting of motor.The circuit

breaker complies with GB14048.1-2012 Low-voltage switchgear and controlgear-Part 1:

General rules; And GB14048.2-2008 Low-voltage switchgear and controlgear-Part 2:
