ABB OT200U30C Industrial Motor Protection Relay

ABB OT200U30C is a three‑pole manual transfer switch in ABB’s OT family, designed to switch a load between two power sources or provide safe isolation in industrial low‑voltage installations. This 3P device is typically panel‑mounted and used in motor control centers and distribution panels where reliable source switching is required during maintenance or in backup‑power configurations. The OT family includes 200 A‑class disconnect switches; the naming convention and catalog entries for OT200‑series parts (for example OT200KFCC3B) indicate a 200 A rating and AC23‑compatible operation at standard industrial voltages, with a three‑pole configuration, though exact electrical ratings for OT200U30C should be confirmed in the official ABB datasheet. The OT200U30C model aligns with that family, offering robust mechanical construction, clear handle operation, and straightforward wiring for interlock and control wiring in panel‑mounted installations. Typical applications include motor feeders, distribution boards, and equipment where a manual transition between incoming feeds is required. For precise voltage rating, current rating, terminal type, mounting style, and any interlock options, consult ABB’s OT‑series documentation or the product listing from authorized ABB distributors.
