Feature: 200 A amperage rating with a two-pole, two-wire design enables direct isolation of heavy loads while keeping wiring simple. The business impact is faster fault clearance and reduced downtime in motor feeders, improving line uptime and operator safety. This configuration is ideal for industrial panels and feeders where robust disconnect capability is essential. Feature: NEMA 4X enclosure in 304 stainless steel delivers superior corrosion resistance and washdown durability. The business impact is extended service life and lower maintenance in harsh environments, with predictable performance in facilities like food processing, chemical plants, and outdoor installations. This translates to lower lifecycle costs and reduced spare-part needs. Feature: Class H fuse provision with fusible without neutral configuration enables safe, selective protection. The business impact is improved safety and coordination with upstream protective devices, minimizing nuisance faults during operation and simplifying field maintenance. Feature: Wide conductor compatibility supports #6 AWG through 300 kcmil Cu/Al, enabling flexible termination and easier upgrades from legacy gear. The installation advantage is faster wiring, fewer field modifications, and better compatibility with a broad range of feeders and motors. Feature: 600 V rating with up to 50 hp maximum (1PH @ 480/600 V) accommodates common plant motors and drive systems. The practical benefit is scalable protection across varied loads, ensuring consistent performance and regulatory alignment across facilities. Feature: UL Listed certification and NEC barrier compliance streamline safety audits and regulatory adherence. Combined with the NEMA 4X stainless enclosure, these attributes reduce total cost of ownership through reliable protection, easier stocking, and documented safety for critical equipment.
