Feature → Business Impact → Application: The LGSDC3600FAG uses the LG frame, three-pole construction, and a 600 A rating to deliver robust protection for PV arrays and AC distribution. This translates to lower fault energy, reduced downtime, and longer equipment life in harsh outdoor environments. Application: Suitable for PVGuard installations where DC and AC protection must coexist without sacrificing speed or coordination. Feature → Business Impact → Application: UL 489 certification and PVGard lineage provide recognized safety and performance standards, reducing regulatory risk and simplifying vendor audits. Application: Ideal for industrial facilities and utility-scale PV projects requiring UL-listed MCCBs in switchgear and control panels. Feature → Business Impact → Application: Line and load terminals with metric mounting hardware enable straightforward installation and reliable connections, cutting wiring errors and field labor time. Application: Integrates seamlessly into existing LG MCCB enclosures and new panel builds for both DC PV strings and AC distribution. Feature → Business Impact → Application: 50 kAIC interrupt rating at 600 Vac ensures fast fault clearance with minimal arc exposure, protecting both equipment and personnel. Application: Critical for systems with high fault current potential, including central inverters and grid-tied PV configurations. Feature → Business Impact → Application: Fixed thermal, adjustable magnetic trip (T185) supports precise coordination with downstream protective devices, reducing nuisance trips and ensuring selective protection. Application: Useful in multi-string PV layouts and hybrid AC/DC protection schemes where selectivity matters.
