1SAM461000R1018

ABB 1SAM461000R1018 MO165-73 is a magnetic-only manual motor starter rated at 73 A and designed for motor applications up to 37 kW at 400 V AC-3. It provides fuse less short-circuit protection, manual ON/OFF switching, a disconnect function, trip-free mechanism and a lockable rotary operating handle. ABB specifies an instantaneous short-circuit current setting of 1022 A and 30 kA Ics at 400 V AC for this exact variant. Because the MO165-73 is a magnetic-only device, a suitable thermal or electronic overload relay must be used where motor overload protection is required. ABB lists compatible accessories including auxiliary contacts, signaling contacts, undervoltage releases, shunt trips, three-phase busbars and power in-feed blocks.
