Application BEC series AC contactor (hereinafter contactor) is a newest design which suitable for using in the circuits up to the rated voltage 690V AC 50Hz or 60Hz,rated current up to 95A,for making,breaking,frequently starting &controlling the AC motor. Combined with the thermal relay, it becomes the electromagnetic starter for protecting the overload circuits.
This series contactor complies with GB14048.4,IEC60947-4-1.
Model and Implication
Working and Installation Condition
■ Ambient air temperature: -5℃--+40℃ and average not more than +35℃ within 24hours;
■ Altitude: no more than 2000m;
■ Air condition: when the highest temperature is +40℃, the air relative humidity is not up to 50%, but the higher
humidity is allowed at lower temperature. Like, 90% humidity at 20℃. The condensate dew should be
considered when at lower temperature;
■ Pollution degree: class 3;
■ Installation category: III;
■ Protection degree: IP20;
■ Installation condition: the gradient angle between installation side and vertical side should not be more than
±5°;
■ Impact and vibration: the contactor must be installed and operate under the circumstances of no obvious
shaking, impact and vibration.
Structure characteristic
■ The wonderful appearance design looks textural, which stops shocking, use more safely and reliably;
■ It can be installed with auxiliary contacts block, time relay and current-limited contacts block, and thermal
relay, then to be other derivative products; ■ This series contactor has small volume, light weight, less power loss, long life and safe and reliability etc;
■ The contactor can be equipped with 1NO auxiliary contact or 1NC auxiliary contact(less than 32A),and 1NO
auxiliary contact+1NC auxiliary contact(more than 40A).In addition, it can be equipped with F4 auxiliary
contact block (2blocks or4blocks);
■ In addition to use screw to install, contactor can be tightened with the standard installing rail of 35mm(BEC-
09~95) and the standard installing rail of 75mm (BEC-40~95).
