The MS132-25B: The headline number is 25 A — that is the motor full-load current it protects. On a 3-phase motor, the starter's thermal overload curve tracks motor heating, so a 25 A setting covers a motor nameplated around 25 A FLA. If your motor draws 20 A, this unit still works; you set the dial to match. The manual motor starter class (manual motor starter) means it combines a disconnect switch, overload relay, and short-circuit protection in one DIN-rail-mountable package — no separate contactor needed for simple on-off and protection. It goes in a control panel on standard DIN rail, with incoming line and outgoing motor leads landed on the screw terminals.
