Applications: Model B25C,B30C,B50C,B63C,B75C,contactors for switching capacitor(hereinafter called contactor)is the derivation products,mainly used in the circuit of AC 50HZ,rated voltage 660V to make and break power capacitors for improving the power factor.

Working conditions:
1.Altitude not exceeding 2000m
2.Ambient temperature not higher than +40℃ and not less than -5℃
3.The relative humidity at +40℃ not more than 50%,at lower temperature ,higher humidity allowed,such as at +20℃, 90%allowed,the product allowed to cover with dew occasionally.
4.The surrounding shall not be effected due to dust,smoke,poisonous gas,steam,or salty pollution,vertical mounting angle not more than 5℃
Basic parameters of contactor:
1.The contactor can pick up steadily at 85%-110% rated control voltage,the drop-out voltage not higher than 75% rated control voltage and not less than 20%rated control voltage.
2.The contactor suits for 8 hour working duty,uninterrupted working duty or spasmodically working duty at operating cycle 120 grade and load factory 60%
3.CA7-10(NO) or CA-01(NC)3-6 pairs of contact can be assembled on the cuniform block of the contactor top
4.Surge limiting capacity:the contactor can limit the surge current,peak value not more than 20times of rated working current
5.Mechanical endurance:not less than 1*10^6 times
6.Electric endurance:not less than 1*10^5 times,operating frequency
