Manual Motor Starters (MMSs)

Manual motor starters (MMSs) are designed to handle the high electrical currents that motors require and provide a convenient and reliable way to start and stop electric motors in machinery and control panels.

NOARK’s manual motor starters help control panel manufacturers meet the electrical code requirements for motor branch circuits by providing the required short circuit and overload protection along with the disconnecting means and on/off control that is required.

NOARK’s MMSs are backed by our signature 5-year warranty to provide the product features and competitive cost you need for your industrial control systems.
