FAQs
The LGEDC3500FAW is a three-pole LG-frame molded case circuit breaker rated for 500 A and 600 V, provided without terminals to simplify integration into standard switchgear or OEM panels. It fits typical AG/DS bus configurations used in PV DC protection schemes and pairs well with Eaton's LV/MCCB ecosystem for straightforward spec-to-install workflows.
This device uses a fixed thermal, adjustable magnetic trip (T185). It provides 65 kAIC at 240 Vac, 35 kAIC at 415/480 Vac, and 18 kAIC at 600 Vac, with a 500 A current rating. The combination supports reliable nuisance-trip reduction and fast isolation for high-current PV fault events in both AC and DC environments.
Yes. With a 600 Vac rating and Vdc class designation, the LGEDC3500FAW is designed for PV DC protection and can coordinate with energy storage interfaces. Its LG frame and three-pole configuration support robust protection across PV arrays and DC distribution networks, while meeting UL 489 requirements for safe integration into solar control panels.
The LGEDC3500FAW is UL 489 listed, confirming compliance with established safety and performance standards for molded case circuit breakers used in electrical protection systems, including PV applications. Certification helps streamline regulatory acceptance and customer auditing for solar installations.
Eaton provides a warranty per policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first. This helps with budgeting for maintenance and parts, supports predictable total cost of ownership, and aligns with typical service intervals for switchgear components in solar facilities.
