Product questions
What is the overload setting range of ABB 1SAM350000R1012?
The MS132-12 has an adjustable overload setting range of 8–12 A and a rated operational current of 12 A. Check the motor nameplate current and the installation requirements before selecting it.
What motor power is the MS132-12 rated for at 400 V?
Its rated three-phase operational power is 5.5 kW at 400 V under AC-3 and AC-3e utilization categories. Power alone does not establish suitability; check the motor current and circuit conditions.
What is the short-circuit breaking capacity of the MS132-12?
The rated service breaking capacity Ics is 100 kA at 400 V AC. The rating varies with voltage; check the prospective fault current and applicable rating for the installation.
Does the MS132-12 protect against phase failure and overload?
Yes. This manual motor starter provides overload and short-circuit protection and phase-failure sensitivity. It has a trip class 10 overload characteristic and a rotary handle for manual switching.
Can the MS132-12 be used on single-phase motors?
The MS132-12 is described as suitable for single- and three-phase applications. Suitability depends on the circuit, motor ratings and correct configuration; confirm the equipment details and serial number where applicable before ordering.
