Overview

The ABB Spec-Setter fused safety switch (SKU: THF3365AJ) is a heavy-duty, 400 Ampere, 3-pole disconnect switch designed for commercial and industrial applications requiring reliable circuit protection and isolation. Rated for 600V AC, this switch meets UL 98 standards for enclosed and dead-front switches, ensuring compliance with the National Electrical Code when used as service equipment. Certified to CSA 22.2 No. 4-04, it exceeds NEMA KS1 standards for enclosed switches (Type HD). Key features include a quick-make, quick-break mechanism for safe operation, a 60/75°C conductor rating, and full cover interlocks to prevent accidental access to live components. The NEMA 1/12 enclosure provides drip and dust-tight protection, making it suitable for indoor environments where contaminants are present. Wire range accommodates copper or aluminum conductors from 4 AWG to 600 AWG. This switch is fusible and accepts Class L fuses without requiring additional kits. For applications requiring a viewing window, the 'VW' suffix can be added, and for 400-600 ampere devices, a left-hand handle ('BL' suffix) is available. With dimensions of 60.1" (H) x 24.6" (W) x 9.1" (D) and a weight of 178 lbs, it is built for heavy-duty industrial use. Typical applications include motor control, power distribution, and general isolation needs in facilities operating at 240V, 480V, or 600V AC. The switch supports horsepower ratings up to 350 HP at 600V AC (3-phase) and 50 HP at 250V DC. Manufactured in the USA by ABB Electrification, the THF3365AJ is a dependable solution for critical infrastructure where operational safety and equipment longevity are priorities.
