Eaton LGU4300FAW Complete MCCB - UL Listed

300 A amperage rating keeps feeders and machines within safe thermal limits while allowing room for short-term surges, reducing overheating and extending equipment life in demanding applications. This translates to lower maintenance costs and higher uptime for critical production lines. The LG-frame four-pole design provides true three-phase protection in a compact footprint, simplifying panel layout and enabling easier retrofits in space-constrained switchgear environments. With fixed thermal and adjustable magnetic trip (T185), engineers can tune protection to motor starting currents and process loads, improving coordination with upstream breakers and downstream fuses for fewer nuisance trips. The unit offers high interrupt ratings—200 kAIC at 240 Vac, 150 kAIC at 480 Vac, and 65 kAIC at 600 Vac—delivering robust short-circuit resilience in heavy-duty service. Without terminals and a weight of 17.6 lb, installation is straightforward in standard enclosures, while 50/60 Hz operation and 80% rating support reliable, energy-efficient performance across global facilities. Certifications and HACR rating further reinforce compliance and motor-load suitability for modern industrial environments. Compatibility with Series G accessories and non-terminal mounting options facilitates scalable protection strategies across panels and machine control applications.
