ABB ACH550-BCR-023A-4B055F267 Enclosed Variable Frequency Drive

ABB ACH550-BCR-023A-4B055F267 Enclosed Variable Frequency Drive is a 15 HP, 23 A, three‑phase motor speed controller designed for HVAC and general industrial applications, packaged in a UL Type 12 enclosure with a bypass circuit and disconnect options (BCR). The 208–230 V variant delivers about 23 A of continuous output and uses base drive frame size R2, with an internal fuse rated CC at 30 A and an external disconnect fuse class J at 50 A; the BCR configuration integrates a bypass switch inside the enclosure to simplify maintenance without power interruption. The BxR suffix denotes either a BCR or BDR configuration within the ACH550 box‑enclosure family, per ABB’s documentation for box enclosure designs in the ACH550 product line. Common uses include controlling ventilation fans, pumps, and conveyors in commercial HVAC, building automation, and light industrial settings.
