Siri CJ40 AC Contactor

Application

CJ40 AC contactor (hereinafter referred to as contactor) is mainly used in power system of AC 50Hz or 60Hz, and rated voltage up to 660V or 1140V, and rated operating current up to 1000A, for long-distance switching on/off the circuits, and it can be used with appropriate thermal overload relay or electronic protection device in a combined way, in order to protect circuits that may subject to operating overload.Standard: IEC 60947-4-1.

Normal operating conditions

Ambient temperature: –5°C~+40°C, the average during 24 hours should not exceed +35°C;

Altitude: ≤2000m;

Atmosphere conditions: At mounting site, relative humidity not exceed 50% at the max temperature of +40°C, higher relative humidity is allowable under lower temperature. for example, RH could be 90% at +20°C, special measures should be taken to occurrence of dews;

Pollution degree: 3

Installation category: III

Installation conditions: the inclination between installation plane and vertical plane is within±5°

Impact and shake: the products should locate in the places where there are no obvious impact and shake.

Structural features

The contactor is of directly acting structure, the contacting and arc quenching system assembled in the top, electromagnetic system located at bottom, the contacts are of dual break point, made of silver alloy. The 63A and above contactors have 6 pairs of auxiliary contacts, three combinations (as table 2).

The arc quenching chamber of CJ40-63A contactors consist of arcing withstand plastic and steel fence, this can overcome the shortage of easy crack for argil arc quenching system, also achieve the higher interrupting capacity.
