1. The mechanical type three speeds switch panel and contactor base consist of fire-retardant plastics. The cintinueator adopts copper and silver alloy with good elasticity.
2. Contact of brake contactor KC damage.
3. Built-in breaker, AC contactor, time relay, thermal relay, current transformer, voltmeter, ammeter, indicating meter in start-delta type starting box .
4. Contactor can be easily retro-fitting auxiliary contact group, and appropriate combination of thermal relay to protect the load that may have been circuits.
5. A line contactor or shunt trip circuit breaker must be installed for safety reasons.
6. Built - in AC contactor, thermal relay and universal self - reset converting switch.
7. As expansion function module of AC contactor, mechanical locking module and AC contactor configurated locking contactor, applies in not frequently operated occasion.
8. And to exchanging the contactor joint noiseless operating of electricity.
9. Based on the previous DIL series contactor, Klckner Moeller Company has developed a new generation of DIL M series contactor.
10. The Line Contactor must have an AC 3 rating equal to or greater than the motor FLC.
11. The closing coil and contactor in the circuit breaker control loop are usually burnt down.
12. The mathematical model of AC contactor is built, and its power quality susceptivity have been carried through simulation research.
13. SCR ( silicon controlled rectifier ) or thyrister can also be substituted for the contactor.
14. The article discusses about the proper selection of static relay test points through introducing the contactor sketch of rectifying static relays with digital dial switches and easy-happening faults.
