The 500 A at 600 Vac rating provides robust protection for high‑current feeders, reducing the risk of cascading faults and equipment damage, which translates to lower downtime and maintenance costs. This is paired with fixed thermal and adjustable magnetic trip (T185) to deliver precise, fast clearing of faults, improving motor protection and startup coordination in demanding loads. With a four‑pole LG frame, line/load terminals, and metric mounting hardware, wiring is simplified and panel density is improved, easing installation and future expansion. The interrupt ratings of up to 100 kAIC at 240 Vac and up to 70 kAIC at 415 Vac (65 kAIC at 480 Vac, 35 kAIC at 600 Vac) provide resilience against high‑fault currents in switchgear and MCCs, supporting safer operations. Certifications (UL Listed, CSA Certified, CE Marked, IEC Rated) and HACR rating ensure regulatory compliance, motor control suitability, and streamlined procurement across global sites. A 20 lb weight and compact 7.22 in footprint enable easy retrofit and compatibility with existing LG frame assemblies, while the one‑year warranty (or 18 months from shipment) adds predictable risk management for maintenance budgets.
