Heavy Duty, Fusible without neutral
Feature: 200A amperage rating with a 600 V maximum. This capability provides a reliable main-disconnect point for large feeders, enabling precise fuse protection and safer startup sequences in demanding environments, making it ideal for service entrances and motor feeders in manufacturing lines. Feature: NEMA 12 and NEMA 3R enclosure in painted galvanized steel. This combination delivers durable protection against dust and moisture, reducing downtime in harsh industrial settings, with practical outdoor readiness when drain-hole modifications are used for NEMA 3R rain exposure in semi-outdoor spaces. Feature: Fusible without neutral and Class H fuse. This arrangement ensures selective coordination and fast disconnection for critical loads while minimizing nuisance trips, suitable for heavy-duty circuits without neutral requirements. Feature: Two-pole, two-wire configuration with #6 AWG-300 kcmil Cu/Al. This simplifies termination and supports large conductor applications, reducing wiring complexity during installation and enabling straightforward field terminations, with a 50 hp max rating for single-phase operation at 480/600 V. Feature: Field-friendly compatibility options including neutral or ground lug kits and a clear warranty. This flexibility accelerates commissioning and reduces lifecycle costs, while the approved service notes and field-modifications support reliable long-term operation in varied installations.
