Annotation:
1. The number of auxiliary contacts is represented by two digits, of which the tens digit is the logarithm of normally open contacts, and the units digit is the logarithm of normally closed contacts.
2. For AC-6b 400vAT, the rated working currents corresponding to various specification codes are 25(18A), 32(24A), 43(29A), 50(36A), 63(48A), 95(58A), 125(87A).
Normal working conditions and installation conditions
- The ambient air temperature should not exceed +40°C, with the average temperature of no higher than +35°C within 24 hours. The lower limit of the ambient air temperature should be -5°C. When the highest temperature is +40°C, the relative humidity of the air should not be higher than 50%. A higher relative humidity is allowed at a lower temperature.
- The altitude of the installation site should not exceed 2000m;
- Pollution level: level 3;
- Installation category: category I;
- Installation condition: the inclination between the installation surface of the contactor and the vertical plane should not exceed 5°.
- Impact and vibration: the product should be installed in a place without obvious shaking, impact and vibration.
Installation wiring diagram
