MS165-42 motor starter: current setting, coordination and installation checks
The ABB MS165-42 is a manual motor starter with a 30–42 A adjustable overload setting and class 10 trip characteristic. ABB lists a 22 kW AC-3 reference at 400 V for this model. The exact order code is 1SAM451000R1015; use the motor nameplate and actual starting duty to confirm suitability rather than relying on the family’s maximum rating.

The table summarizes family or catalog values for identification and initial selection. Confirm the nameplate, environmental limits, standards, revision and options for the exact device before procurement or engineering approval.
Application and system selection
The MS165 combines manual switching with motor-circuit protection. It is commonly considered for larger direct-on-line motor circuits where a compact local isolating and protection device is appropriate. Confirm whether the application needs a separate contactor, remote control, auxiliary indication or an upstream short-circuit protective device.
Configuration and compatibility
Check coordination against the selected contactor and upstream fuse or breaker using ABB’s current coordination tables. Verify the motor full-load current falls within 30–42 A, and review prospective fault current, ambient temperature and enclosure conditions. Accessories across MS116, MS132 and MS165 may share some interfaces, but confirm the exact accessory part number before ordering.

Installation and commissioning
Isolate and prove the circuit dead before wiring. Mount the starter securely, select conductors and tightening torque from the current manual, then set the dial to the motor nameplate current. Test trip, reset, interlock and downstream contactor behavior under the approved commissioning procedure and record the final setting.
Replacement and procurement information
For a quotation or replacement review, provide the complete designation MS165-42, the order code where applicable, serial or hardware revision, quantity, operating environment, connected equipment and required delivery date. Include a legible nameplate image and relevant wiring, loop or switchgear drawing so the exact interface and configuration can be checked.
Ask the supplier to confirm accessories, revision compatibility and any approved successor in writing. Do not select solely from a family name or product photograph. Follow the current ABB installation and safety instructions for the exact unit.
