Applications & Use Cases

The ABB MS132-12 is purpose-built for the protection and manual switching of three-phase motors up to 12 A in industrial environments. Typical applications include conveyor drives, pump motor protection, compressor starters, HVAC fan motor control, and machine tool panels. Its 100 kA breaking capacity at 400 VAC makes the MS132-12 suitable for installation in high fault-level distribution systems without additional current limiting fuses. The compact 45 mm DIN rail footprint allows space-efficient motor control centre (MCC) design, while its wide range of approvals — including ATEX and IECEx — enables deployment in hazardous area installations.
