Short Description:

The W1 series intelligent low-voltage air circuit breaker (hereinafter referred to as circuit

breaker) is suitable for distribution networks with frequency of AC 50Hz, rated voltage up

to 660V (690V) and below and rated current ranging from 200A to 6300A. It’s used to

distribute electrical energy and protect lines and power equipment from overload,

undervoltage, short circuit, single-phase grounding and other faults. The circuit breaker has

intelligent protection function and precise selective protection, can improve power supply

reliability and avoid unnecessary power outages. Meanwhile, it has open type communication

interface and can be used for four remote operations to meet the requirements of the control

center and automation system. The circuit breaker has pulse withstand voltage of 8000v at

altitude of 2000 meters (corrected according to standards for different altitudes, with maximum

voltage not exceeding 120oov). The circuit breaker without intelligent controller and sensor

can be used as isolator, marked asThe circuit breaker complies with standards such as GB

14048.2 Low-voltage switchgear and controlgear-Part 2: Circuitbreakers and IEC60947-2
