Project Description

3TF ac motor contactor

3TF 3TB electric contactor for ac control motor stater

3TF 3TB electric contactor for ac control motor stater is suitable for circuits of frequency 50/60Hz,rated insulation voltage up to 1000V and rated operation current 9-475A under AC-3 duty. It is mainly for making and breaking of electric circuits at a long distance; for frequent starting and stopping. It can work with thermal relay to compose a magnetic starter. The products accords with standards  IEC 60947-4-1 and GB14048.4.
