FAQs
The LGC4400FAG uses metric mounting hardware and line/load terminals designed for four-pole LG-frame assemblies. This enables straightforward mounting in modern electrical panels and motor control centers, reduces wiring complexity, and supports fast commissioning. Its compact footprint (4.09 in depth, 7.22 in height and width) helps maximize panel density while maintaining safe clearances.
LGC4400FAG offers 200 kAIC interrupt rating at 240 V, 100 kAIC at 480 V, and 50 kAIC at 600 V. The trip system combines fixed thermal protection with an adjustable magnetic element (T185), enabling precise coordination and selective protection for downstream devices. This configuration supports reliable fault isolation in demanding industrial applications.
Yes. The unit is UL Listed, CSA Certified, and IEC Rated, with HACR rating and CE compliance noted in the catalog. This combination supports global procurement, regulatory alignment, and simplified audits across multinational facilities, reducing the need for multiple device variants and streamlining maintenance and training.
Best suited for high-current control panels, motor control centers, and heavy-load feeders in manufacturing and process industries. Its 400 A rating, four-pole LG frame, and robust interrupt performance enable reliable protection for large machines and critical automation lines, while its compact footprint assists in space-constrained panel assemblies.
Maintenance is straightforward due to standardized line/load terminals and a durable LG-frame design that tolerates frequent switching. The 400 A rating and high interrupt capacity reduce downtime during faults, delivering faster fault clearance and reduced wear on downstream equipment. The product warranty aligns with Eaton’s policy, offering a clear remediation window post-installation.
