AC contactors NYKC-D50 4P
ApplicationKPD series AC contactors are suitable for frequency 50/60Hz,rated insulation voltage up to 1000V,rated operation current 9~150A
KPD series AC contactors are suitable for frequency 50/60Hz,rated insulation voltage up to 1000V,rated operation current 9~150A under AC-3 duty.It is mainly used for making and breaking electric circuits at a long distance & for frequent starting, stopping & controlling AC Motors.It is used in combination with thermal relay to compose a magnetic motor starter. The products comply with IEC60947-4. Combined with the auxiliary contact block, timer delay & machine-interlocking device etc, it becomes the delay contactor, mechanical-interlocking contactor, star-delta starter. With the thermal relay, it is combined into the electromagnetic starter.
