The 2000 A amperage rating paired with a 480 V voltage rating delivers the heavy-duty performance required for high-current feeders in industrial facilities, enabling you to consolidate switching duties without additional gear. The integrated control power transformer simplifies wiring and accelerates commissioning by providing a readily available 120 V control source for protection relays and control circuits, reducing field labor and potential wiring errors. An arc energy reduction relay is included to minimize arcing during switching events, which translates to safer maintenance windows, extended contact life, and lower arc-flash exposure for personnel. Matched current transformers (CTs) support accurate protection and MET signaling, streamlining integration with existing protection schemes and metering. Bottom feed and bottom-fuse configuration simplify panel integration and cable routing, while a three-pole, three-wire design ensures synchronized three-phase protection for motors and feeders. UL Listed certification reinforces compliance with safety standards, and the rugged construction with a 16 in length, 24 in width, and 28 in height footprint makes it suitable for standard switchgear frames. The unit weighs 175 lb, balancing durability with manageable handling in the field. Overall, the SCB2033B120480E delivers reliable protection, faster installation, and a clear path to regulatory compliance for demanding industrial environments.
