Cj19 series AC contactor for switching shunt capacitor (hereinafter call -contactor) is mainly used in the system ofAc 50 or 60Hz, rated voltage up to 380V, for switching on/off shunt capacitor in the low voltage reactive compensating bank. Ifthe contactor with surge restrained device, it can effectively prevent surging current when closing and over voltage duringopening.
Δομή:
The contactor is of direct-action double break structure, the contact system consists of upper and downwardlayout, upper part has 3pairs of contacts and current limiting resistance what become surge restrained device, when closingcurrent limiting contacts will make several milliseconds at firstly, then working contact is made closed later, current limitingcontact will be released under the action of everlasting magnet and spring, current limiting resistance is switched off, capacitorthen operate normally, inner wiring diagram as Drawing 4
Cj19 25~43 contactor has 2 pairs of auxiliary contacts, CJ19 63~95 contactors have 3 pairs of auxiliary contacts, the terminals have provided insulating cover for safety, coil terminals have been marked clearly. CJ19 25~43 can be mounted by screw or by 35mm railway, a dismount able square blank card in cover is provided for spare when required to print something as user. CJ19 63~95 can be mounted on 35 ή 75 mm railway.
