ABB 1SAM451000R1018 | MS165-73 Manual Motor Starter, 62-73A Current Range

ABB MS165-73 manual motor starter - 62 to 73 A

ABB 1SAM451000R1018 is an ABB MS165-73 manual motor starter for motor protection, local motor switching and low-voltage control panel assembly. The ABB part number 1SAM451000R1018 is selected for motors with full-load current in the 62 to 73 A range, making it suitable for pumps, fans, compressors, HVAC systems, conveyors, small machines and factory maintenance panels.

The MS165 frame is the higher-current ABB manual motor starter family, built in a compact 55 mm width for demanding motor protection up to the larger pump, fan and machine sizes. As a manual motor protector, ABB 1SAM451000R1018 combines overload protection, short-circuit protection, phase-failure protection, a disconnecting function, temperature compensation, a trip-free mechanism and a clear rotary operating handle.

MS165 is a compact and powerful range for motor protection up to 45 kW (400 V) / 80 A in width of 55 mm. They offer a reliable protection for motors in the event of overload or phase failure. The devices have trip class 10. This type has also a clear and reliable indication of fault in a separate window in the event of short-circuit tripping. Further features are the build-in disconnect function, temperature compensation, trip-free mechanism and a rotary handle with a clear switch position indication. The manual motor starter (also known as motor protection circuit breaker or manual motor protector) is suitable for three- and single phase applications. The handle is lockable to protect against unauthorized changes. Auxiliary contacts, signaling contacts, undervoltage releases, shunt trips, power in-feed blocks are available as accessory. These are suitable throughout the MS116/MS132/MS165 range.
