Overview

The ABB Spec-Setter SW FUSED HD (SKU: THF3366AX) is a heavy-duty, fused safety switch designed for industrial applications requiring reliable power disconnection and fault protection. This 3-pole switch operates at 600V AC with a 600A rating, making it suitable for service entrance equipment, motor control centers, and distribution panels. It is certified to UL Listed, cUL Listed (UL98/CSA-C22.2 No. 4-04), Federal Specification WS-865C, and NEMA KS1-2013 standards, ensuring compliance with stringent safety and performance benchmarks. The switch features a Type 4X enclosure constructed from 316 stainless steel, providing superior corrosion resistance for harsh environments. It accepts Class L fuses exclusively, meeting NEC standards for fault protection. The "AX" suffix indicates this specific enclosure type for 400-600A devices. Optional configurations include bottom-feed (BL suffix) for 400-600A devices, which reverses the handle to the left side, and factory-installed auxiliary contacts (H, K, and R) for enhanced monitoring and control. Optional viewing windows (VW suffix) allow visual confirmation of the switch's status, while groundable and bondable neutral kits adapt to various system configurations. This switch is seismic-certified and rated for service entrance use, except for specific 1200A solidly grounded wye systems per NEC 230.95. Manufactured in the US, it combines durability, compliance, and flexibility for industrial power distribution systems.
