Eaton JGPVS3100W PV Guard Solar MCCB - UL Listed

Feature → JG frame three-pole design provides a complete molded case circuit breaker with a 100 A rating and 600 Vdc capability. Impact → The 1.2 kAIC interrupt rating minimizes arc energy and protects PV conductors, cables, and downstream equipment in fault conditions. Application → Ideal for three-phase DC strings in rooftop arrays and small to mid-size PV installations where compact, rugged protection is essential.\n\nFeature → Fixed thermal and fixed magnetic trip (T186) delivers stable protection against overloads and short circuits. Impact → This reduces nuisance trips and ensures fast, predictable fault clearance under PV fault scenarios. Application → Supports reliable operation in PV inverters and DC bus configurations in commercial solar projects.\n\nFeature → 80% rated design aligns operating current with actual PV string loads. Impact → Improves system efficiency and extends component life by avoiding over-protection during partial load conditions. Application → Beneficial in shaded or partial-output PV deployments where continuous protection at near-rated current matters.\n\nFeature → Terminals are not included with frames; plan for compatible terminals and wiring. Impact → Lets installers select lug options that match enclosure design and wire size, simplifying field assembly. Application → Flexible integration in retrofit or new builds where terminal compatibility drives protection strategy.\n\nFeature → UL Listed certification confirms safety and compliance for PV protection devices. Impact → Supports code-compliant installations and reduces procurement risk across electrical and solar projects. Application → Widely accepted in North American solar installations and industrial electrical protection schemes.
