ABB MO165-65 Manual Motor Starter

Core Performance & Industrial Application

The ABB MO165-65 (1SAM461000R1017) is a magnetic-only manual motor starter of the MO165 series for motor short-circuit protection without fuses.

It manually switches loads and motors on/off and provides instantaneous magnetic short-circuit trip; overload protection pairs with separate overload relays or motor controllers.

The 55 mm compact housing delivers high short-circuit breaking capacity up to 50 kA (Icu) at 400 V AC in a narrow panel footprint.

It features a built-in disconnect function, trip-free mechanism, rotary handle with clear position indication and padlock lockout.

It supports three-phase and single-phase applications, with auxiliary contacts, undervoltage release and bus-bar accessories available.

It is widely used as spare replacement in motor control panels and feeder protection circuits.
