Eaton
Part number
LGH3300FAW

Quick Summary

The Eaton LGH3300FAW MCCB protects industrial power systems by interrupting fault currents in three-pole LG-frame assemblies. Choosing a breaker with mismatched trip settings or poor coordination often leads to nuisance trips and costly downtime. This LGH3300FAW carries CE marking and UL/CSA listings, and is IEC-rated, aligning with global safety and regulatory standards. Designed for Series G LG-frame protection, it enables reliable protection coordination, easier installation, and reduced total cost of ownership. With 300 A current rating, 50/60 Hz operation, and fixed thermal with adjustable magnetic trip (T185), it suits motor control and panel feeder duties. Investing in the LGH3300FAW helps ensure high interrupt capability (100 kAIC at 240 V) while maintaining HACR compliance for circuit efficiency.

LG frame three-pole protection with a 300 A rating provides robust upstream protection while saving panel space. This combination reduces fault exposure and supports precise coordination with downstream devices, translating into fewer nuisance trips and safer motor start-ups in automated lines. In practice, LGH3300FAW fits Series G assemblies, streamlining procurement and field upgrades. Trip characteristics: fixed thermal with adjustable magnetic (T185) allow precise protection curves. Business impact: improved selectivity and faster fault interruption, minimizing collateral damage to downstream equipment. Application: machine controls and conveyors where selective coordination is critical. Interrupt ratings: 100 kAIC at 240 VAC, 65 kAIC at 480 VAC, 35 kAIC at 600 VAC; 50/60 Hz operation. Business impact: high fault tolerance across typical industrial voltages; Application: plant power distribution and critical loads with varied supply swings. Terminals: without terminals, enabling compatibility with lugs or plug-in accessories. Business impact: installation flexibility and reduced inventory of terminals; Application: retrofit projects and modular panel builds where plug-in accessories are used. Certifications and compliance: CE marked; UL Listed; CSA Certified; HACR rated; 80% rated as noted. Business impact: ensures market-wide acceptance and code compliance, simplifying approvals and long-term support. Physical footprint: 4.09 in depth, 5.48 in height and width; weight 13.5 lb.
