CJ19 Series AC contactor for switching shunt capacitor

CJ19 Series AC contactor for switching shunt capacitor surge restrained The terminals have insulating cover 35 75mm railway

  Application

CJ19 series AC contactor for switching shunt capacitor(hereinafter call -contactor) is mainly used in the system of Ac 50 or60Hz, rated voltage up to 380V, for switching on / off shunt capacitorin the low voltage reactive compensating bank. If the contactor withsurge restrained device, it can effectively prevent surging current whenclosing and over voltage during opening.

Structure

The contactor is of direct-action double break structure, the contactsystem consists of upper and downward layout, upper part has 3pairs of contacts and current limiting resistance what become surge restrained device, when closing current limiting contacts will make several milliseconds at firstly, then working contact is made closed later, current limiting contact will be released under the action of everlasting magnet and spring, current limiting resistance is switched off, capacitor then 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 dismountable square blank card in cover is provided for spare when required to print something as user. CJ19 63 ~ 95 can be mounted on 35 or 75 mm railway.
