  The SM1B series is a new generation of manual starters with thermal and magnetic trip releases. Motor control and protection, up to 20HP at 460V, are possible by the choice of suitable adjustment range, 0.1 to 32A. A magnetic trip indicator integrated on the SM1B starters avoids dangerous closing operations during short-circuit conditions, previously disconnected by the starter. The SM1B types are suitable for isolation.
