ZHC20 ZNFO Transcender series AC contacton

ZHC20 series AC contactor is mainly used in the electric power circuits with the frequency of AC 50Hz (or 60Hz), the rated working voltage of up to 690V (or 1140V) and the rated working current of up to 1000A for connecting and breaking circuits, and working with the appropriate thermal relay or electronic protection device to form the motor starter to protect the circuits that may be overloaded.Executive standards:GB14048.4 and IEC60947-4-1,etc.

Advantage

All products of the company can be customized for production according to user usage scenarios.

Type and meaning

Normal working conditions and installation conditions

□The ambient air temperature should be-5℃~+40℃,with the average temperature of no higher than+35℃ within 24 hours.

□Altitude: not higher than 2000m;

□Atmospheric conditions: when the highest temperature is +40℃, the relative humidity of the air should not be higher than 50%; A higher relative humidity is allowed at a lower temperature, such as 90% under 20℃, Special measures should be taken for occasional condensation due to temperature change;

□Pollution level: level 3;

□Installation category: category III;

□Installation condition: the inclination between the installation surface and the vertical plane should not exceed±5°;

□Impact vibration : the product should be installed and used in a place without obvious shaking,impact and vibration.

Structural features of the product

□The contact system of the contactor is direct-acting with double breakpoints. For ZHC20-40A and above, the auxiliary contacts are installed on both sides of the main contact as independent components, which are electrically separated;

□ZHC20-10-25A products may be installed by screws or by 35mm standard card track;

□ZHC20-10-16A products have double breakpoints to simply break the are extinguishing chamber, and the rest adopt the plastic grid are extinguishing chamber, which has the advantages of high breaking capacity and high reliability;

□ZHC20-63~630 power saving products have the DC general power saving module, which not only can derive silencing energy saving products or DC operated products,but also do not occupy auxiliary contacts,thus greatly improving the reliability and life of products.
