Cutler-Hammer MSH2.1A Manual Starter provides manual on/off control for motor circuits with built-in thermal overload protection. It incorporates a thermal overload heater element rated 1.68–1.83 A, a key specification for selecting the appropriate protection for the connected motor. The MSH2.1A is designed to enable direct, local control of a motor while automatically protecting the circuit from overload conditions. This model is suited for control panels or standalone motor applications where a simple, local start/stop solution with integrated overload protection is required.
