200 A, two-pole design with Class H fusible elements deliver high-current protection without neutral. This provides a clear business impact: safer operation, reduced arc-flash risk, and predictable fuse performance in demanding environments. It finds application in service entrances, motor feeders, and control panels where quick fuse changes minimize downtime and keep critical processes online. NEMA 1 painted steel enclosure protects internal components from dust and incidental contact, improving longevity in indoor switchgear. Rugged construction lowers maintenance costs and reduces field failures in environments with door openings and vibration. The design is compatible with a neutral or ground lug kit, expanding installation options and simplifying compliance. 600 V rating and up to 50 HP at single-phase operation (480–600 V) offer flexible motor control while keeping cable sizing practical. The wiring range of #6 AWG to 250 kcmil Cu/Al supports a wide range of feeders, speeding up installation and reducing mis-wiring risk. UL Listed and NEC 230.62 barrier compliance ensure regulatory alignment and safer workplaces. The catalog notes confirm suitability for service entrance use when a lug kit is installed, enabling streamlined integration with new or existing electrical rooms. Warranty of one year from installation (or 18 months from shipment) provides reassurance and predictable support. The fusible safety switch design minimizes downtime while enabling efficient spare parts management for ongoing operations.
