The JGEDC3250NN frame-only design reduces installation time by providing a compact, ready-to-mate frame that can be paired with Cu wire and mounted without collars, simplifying field assembly and maintenance. This translates to lower labor costs and faster system commissioning for PVGuard solar protection schemes, especially in tight electrical rooms and retrofit projects. With a 250 A amperage rating and a 600 Vac / 250 Vdc voltage range, it delivers consistent fault protection across AC and DC PV circuits, helping you meet NEC and UL 489 requirements while minimizing nuisance tripping in evolving PV arrays. The 35 kAIC interrupt rating at 600 Vac provides a strong safety margin for fault events, reducing downstream damage and improving system reliability. Its three-pole configuration supports balanced protection across solar string inverters and combiner boxes, while the frame type JG and class Vdc designation align with DC utility protection standards. Compatibility with Eaton PVGuard accessories and catalogs streamlines procurement, stocking, and lifecycle support, delivering long-term value and predictable maintenance costs. The included warranty, governed by Eaton policy 25-000, offers one year from installation or eighteen months from shipment, ensuring confidence in performance and post-sale support for mission-critical solar deployments.

FAQs
The JGEDC3250NN is a frame-only JG-frame unit designed for straightforward integration with compatible lugs, Cu wire, and mounting arrangements. As a three-pole, 250 A device rated for 600 Vac and 250 Vdc, it fits standard MCCB enclosures used in PVGuard installations. Ensure proper clearance, connect per UL 489 guidelines, and verify compatibility with existing PVGuard components to minimize commissioning time and avoid misalignment during retrofits.
Verify amperage rating of 250 A, voltage ratings of 600 Vac / 250 Vdc, interrupt rating of 35 kAIC at 600 Vac, and three-pole construction. Confirm frame type is JG and that it is configured as frame-only. These specs support reliable protection for PV arrays and inverters while meeting safety standards.
Yes. The JGEDC3250NN is designed as a PVGuard solar circuit breaker frame, with frame-only flexibility that integrates with PVGuard protection schemes. Its 35 kAIC interrupt capability and UL 489 certification align with commercial PV protection requirements, providing robust fault mitigation for solar inverters, string circuits, and protection assemblies.
JGEDC3250NN carries UL 489 certification, a critical standard for molded case circuit breakers used in electrical protection systems. This certification helps meet safety codes and procurement specifications in many markets, reducing compliance risk for PV installations and simplifying approval workflows with inspectors and auditors.
Eaton provides a warranty under policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first. This coverage supports reliability and reduces risk during commissioning and early operation, contributing to lower long-term maintenance costs and predictable ROI for PVGuard protection projects.
