Tips for using the AC contactor
- The open type cannot be used inflammable and explosive places and all places with a lot of conductive dust, nor can it be used outdoors without protective measures because sparks and arcs are generated when the load is disconnected.
- When using, pay attention to whether the contacts and coils are overheated. The three-phase main contacts must be synchronized, and the arc must not be too large when breaking.
- When the AC contactor controls the motor or circuit, it must be used in conjunction with an overcurrent protector. The contactor itself has no overcurrent protection performance.
- The suction surface of the short-circuit ring and the electromagnet should be kept intact and clean.
- Due to poor heat dissipation conditions, when the contactor is installed in the control box or protective enclosure, the ambient temperature is relatively high, so the capacity should be appropriately reduced for use.
