          PRODUCT DESCRIPTION

          OS30AJ12 Three-Pole Fusible Disconnect Switch

          ABB OS30AJ12 is a three-pole fusible disconnect switch in the PowerLine range. ABB lists this model at 30 A and up to 600 V AC under its North American ratings. It accepts Class J fuses rather than the Class CC fuses specified for the similarly named OS30ACC12.

          The switch supports base or DIN rail mounting and can be paired with a documented shaft and handle for an enclosure. Match the switch marking, fuse class and enclosure hardware before replacement, and check the complete approved combination separately when specifying a short-circuit rating.

          SYSTEM & REPLACEMENT CHECK

          Information needed before ordering

          Three direct checks to secure your system integration and minimize ordering risks.

          Information

          System integration Replacement check Manuals & support
          SYSTEM INTEGRATION

          Integrate OS30AJ12 in the documented ABB PowerLine arrangement

          OS30AJ12 is the three-pole, 30 A Class J fusible disconnect in the ABB PowerLine range. Select the fuse arrangement for this exact model and apply its voltage and phase-specific load ratings, rather than those of the similarly named Class CC version.
          ABB lists base or DIN rail mounting and copper conductor compatibility from 18 to 8 AWG. Coordinate the installed switch with the specified shaft, door handle and enclosure arrangement; the switch designation alone does not identify every component required for the complete assembly.
          The listed combination document must be read as a complete component combination with its stated protective-device conditions. Do not transfer a combination short-circuit rating to an arbitrary enclosure or fuse arrangement, and do not confuse insulation voltage with maximum operating voltage.

          Features:

          • Three-pole Class J arrangement
          • Base or DIN rail mounting
          • Combination-specific rating reference
          Class J selection and a valid listed combination are required; a general catalogue rating does not qualify an unrelated assembly.
          INTERCHANGEABILITY

          Verify OS30AJ12 before replacement

          Verify OS30AJ12 on the switch and compare the order label with the offered item. The existing carton photo identifies 1SCA022548R9810; check the supplied unit itself and preserve the Class J distinction when requesting a quotation.
          Compare the mounting method, shaft alignment and handle selection with the installed assembly. Review the conductor and terminal requirements against the applicable ABB instructions, and confirm separately which fuses, handle and shaft are included in the offer.
          After authorized isolated replacement, verify the mechanical selection and the required circuit checks using the approved installation procedure. Reconfirm the exact listed combination before relying on its short-circuit rating, particularly if any protective or enclosure component has changed.

          Features:

          • OS30AJ12 identification
          • Matching shaft and handle
          • Class J fuse selection
          OS30ACC12 uses a different fuse class and is not established as a direct replacement for OS30AJ12.

          • Product and manufacturer directory links
          Documentation for OS30AJ12 must match the complete installed product identity, the documented ABB PowerLine configuration and the supplied fusible disconnect switch before service.

          FREQUENTLY ASKED QUESTIONS

          Questions buyers ask about OS30AJ12

          Direct answers about identity, compatibility, stock, warranty, payment and shipping.

          • Is OS30AJ12 the same as OS30ACC12?

            No. Both appear in the 30 A range, but ABB specifies Class J for OS30AJ12 and Class CC for OS30ACC12. Verify the fuse marking before choosing a replacement.

          • How does the motor rating change between 480 and 600 V?

            ABB lists 15 hp at 480 V and 20 hp at 600 V for three-phase motors. Use the rating for the actual voltage and phase; do not apply the 600 V horsepower rating at a lower voltage.

          • Can this switch be mounted on DIN rail?

            ABB lists both base and DIN rail mounting for this model. Confirm the installed mounting method and the switch-to-handle arrangement against the enclosure documentation.

          • Which conductor sizes appear in the ABB catalog?

            The model row specifies copper conductors from 18 to 8 AWG. Use the actual label and manufacturer documentation to verify the connection limits of the unit being installed.

          • Does the switch designation include a door handle and shaft?

            Not by itself. ABB shows the switch, shaft and handle as separately selected components for a complete arrangement. Confirm exactly which components are included in the quotation.

          • When can the catalog’s combination short-circuit rating be used?

            Only when the specified components and conditions of the listed combination apply. Match the complete combination reference; do not use the table to assign a rating to an unrelated assembly.

          • Why does the IEC insulation value differ from the 600 V rating?

            The catalog lists insulation voltage and North American maximum operating voltage in separate rows. The insulation figure is not permission to operate above the applicable rating.

          • Where can a buyer verify the exact ordering reference?

            Match OS30AJ12 on the switch label and compare the carton label with the offered item. The current product photo shows 1SCA022548R9810; confirm the supplied unit’s marking before ordering.
