ABB OT32B2A1-180 Industrial Motor Protection Relay

ABB OT32B2A1-180 is an industrial motor control accessory from ABB's OT32 family, sold as a Disconnect Switch Kit that provides isolation in motor circuits while supporting compact, integrated control alongside ABB contactors. The B2A1-180 suffix identifies the specific kit configuration within the OT32 lineup, specifying the exact assembly and mounting options offered for installation in industrial panels. Distributors label this part as an ABB OT32B2A1-180 Disconnect Switch Kit, designed to sit in motor control applications where reliable electrical isolation is required and where ABB motor protection components are part of the starter solution. In typical panel installations, such kits are used to facilitate safe maintenance and routine starting sequences by physically interrupting the main circuit when opened. For precise electrical ratings, enclosure dimensions, wiring terminals, mounting footprint, and accessory compatibility, consult ABB’s official product literature or an authorized distributor’s datasheet, and verify interoperability with your ABB contactors and overload protection devices to form a complete starter assembly.
