Model Description

Normal working environment and installation conditions

● The ambient air temperature is -5 °C ~ +40 °C, and the average temperature within 24 hours does not exceed +35 °C.

● Altitude: no more than 2000m.

● Atmospheric conditions: The relative humidity of the air at the installation site does not exceed 50% at a maximum temperature of +40 ° C; higher relative humidity is allowed at lower temperatures, for example, 90% at +20 ° C, due to temperature changes Special measures should be taken for occasional condensation.

● Transportation and storage temperature; -25 °C - +55 °C, short-term (within 24h) can be +70 °C.

● Pollution level: 2.

● Installation category: 110

● There should be no significant impact or vibration at the installation.

● Mounting type: Adopt TH35-7.5 type mounting rail.

● The product is installed vertically, and the inclination of the mounting surface and the vertical surface is not more than ±5.

● Operation (operation) condition: When the ambient air temperature is in the range of -5°C to +40°C, the rated control power supply voltage Us is applied to the contactor coil to make it heat up to a steady state, and the contactor is at the rated control power supply voltage Us. The pull-in between 85% and 110% is released and disconnected between 75% and 20% of the rated control supply voltage Us.

● Mechanical life: The mechanical life of the contactor is not less than 1 million times.
