ABB MS165-65 Manual Motor Starter Thermal Magnetic

The ABB MS165-65 Manual Motor Starter Protector, part of ABB's MS165 series, is a 3-pole, thermal-magnetic motor protection device that provides manual switching, overload protection, short-circuit protection, and phase-loss protection for three-phase motors. In a compact 55 mm-wide housing suitable for 35 mm DIN rail or panel mounting, it accepts up to 690 VAC / 250 VDC and offers a current adjustment range of 52–65 A with a rated operational current (Ie) of 65 A and a 30 kW motor rating at 400 VAC, plus a breaking capacity up to 50 kA at 400 VAC. The unit includes a built-in disconnect, a trip-free mechanism, and a lockable rotary handle for safe maintenance in motor control centers, electrical panels, and OEM machinery, with an IP20 enclosure. Common applications include industrial automation systems, conveyors, pumps, compressors, HVAC equipment, water treatment facilities, and process control environments, and it is a common replacement for older starters such as the Siemens 3RV2041 Motor Starter Protector.
