Applications & Use Cases
The MO132-25 is ideally suited for direct-on-line motor starting and short-circuit protection in industrial control panels, machine building, HVAC systems, conveyor drives, pump stations, and process automation equipment. Its magnetic-only trip mechanism ensures fast and reliable short-circuit disconnection without thermal overload intervention, making it the preferred choice when a separate thermal overload relay is used downstream. The 45 mm compact footprint and 3-pole configuration simplify DIN rail installation in space-constrained enclosures, while the broad international certification portfolio — including marine approvals from DNV, LR, RINA, and RMRS — qualifies the ABB MO132-25 for both onshore and offshore industrial environments.
