600 A rating provides robust feeder protection for motors and control circuits in demanding industrial environments. The LGU4600FAG uses fixed thermal with adjustable magnetic trip to deliver precise coordination with upstream devices, reducing nuisance trips while preserving fast fault clearance during peak loads. This protective architecture supports reliable machine operation, simplifies protection tuning for varying duty cycles, and minimizes unexpected panel outages in automation initiatives. With a 600 Vac rating, this LG-frame MCCB handles safe switching across three-phase loads without sacrificing insulation margins or electrical safety. The four-pole configuration ensures synchronized tripping across all phases, improving system integrity for motor starters, drives, and conveyors. Designers can rely on predictable performance during startup transients and fault conditions, enabling better coordination with contactors and overload relays in control panels. Line and load terminals combined with metric mounting streamline field installation and future servicing. The LGU4600FAG is a complete four-pole breaker that fits standard Series G assemblies, supporting plug-in compatibility and straightforward retrofits into existing panels. Its compact 7.22-inch footprint and standardized mounting reduce installation time and enable cleaner wiring schemes in control enclosures. Interrupt ratings of 65 kAIC at 600 Vac, 150 kAIC at 415/480 Vac, and 200 kAIC at 240 Vac provide durable fault current protection for high-energy processes and critical machinery. This capability supports selective coordination with upstream breakers and fuses, helping minimize outages and maximize uptime. The four-pole design also helps ensure fault current remains contained within the protected circuit. UL Listed, IEC Rated, CSA Certified, and CE Marked, LGU4600FAG meets global safety and performance standards. HACR rated catalog notes and Eaton's extensive literature provide installation guidance, performance validation, and lifecycle-support resources, reducing risk and simplifying commissioning.
