QC12 series electromagnetic starterDetailed product description：

1. Scope of application of QC12 series electromagnetic starter

The QC12 electromagnetic starter is suitable for use in power circuits with AC 50Hz and voltage up to 380V, for remote direct control of the starting and stopping of three-phase squirrel cage induction motors The reversible starter can also control the reverse rotation of the motor, and when the grid voltage disappears, the starter plays a role in voltage loss protection Starters with thermal relays can also provide protection against motor overload and phase failure operation.
