Product questions
What current range does ABB MS165-32 cover?
The overload setting range is 23–32 A. ABB advises selecting a starter so the actual motor current falls within its setting range; check the motor nameplate and application requirements.
What motor power is MS165-32 rated for at 400 V?
ABB lists 15 kW at 400 V for AC-3 operation. Power alone is not enough to select the starter: check the motor current against its 23–32 A setting range and verify the application.
What protection does 1SAM451000R1014 provide?
The MS165-32 uses thermal overload and electromagnetic short-circuit protection, with phase-loss sensitivity. Its overload trip class is 10; it also has a manual disconnect function.
Can MS165-32 be used on a single-phase motor?
ABB describes the MS165 as suitable for single- and three-phase applications. Confirm the motor current, circuit arrangement and applicable ABB wiring information before selecting it.
