The 400 A amperage rating enables direct disconnection for large motor loads in manufacturing lines, reducing wear on upstream contactors and simplifying panel design. This translates to higher equipment uptime and lower maintenance costs. The unit is a two-pole, 240 V disconnect suitable for heavy machinery and process lines, making it a drop-in upgrade for existing HDSS installations. Fuse class provision with Class H fuses and fusible without neutral reduces arc flash risk and improves fault isolation, delivering safer start-ups and easier fuse replacement in field service while maintaining compliance with industry standards. NEMA 4 painted steel enclosure protects internal components from dust, moisture, and corrosion in plant environments; paired with UL Listed certification, it supports exterior mounting and outdoor applications. Max HP ratings of 50, 125, and 50 hp (3PH with standard fuse/time-delay/250 Vdc) enable compatibility with a wide range of motors and drives. The wiring accommodates large conductor sizes (Cu/Al) such as up to (2)300 kcmil or (1)750 kcmil, easing installation and future upgrades. The NEC 230.62 barrier compliance and rugged HDSS design provide improved safety and regulatory alignment, reducing lifecycle costs through fewer replacements and more predictable protection in mission-critical schemes.
