CJ19-43 Series Switch-over Capacitor Duty Contactor

Specifications

1.Application
CJ19 series changeover capacitor contactor is mainly applicable to a power line of AC 50Hzor 60Hz,

rated working voltage up to 380V. It is used to put a low voltage parallel connectedcapacitor

in operation or switch it off in a low voltage reactive power compensation device. Thecontactor

is equipped with a surge suppressor, which can effectively reduce the surge currentpassing

through the capacitor at weitching on and suppress the over-voltage at switching off. The product is in conformity with the standards IEC947-4-1.

2.Structure:

The contactor is of direct-action double break structure, the contact
system consists of upper and downward layout, upper part has 3 pairs
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

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.
