Eaton Specification Sheet - JGHDC3070FAW
Feature: The JGHDC3070FAW uses a 70 A amperage rating in a three-pole complete breaker with fixed thermal and adjustable magnetic trip (T185). Business impact: This combination delivers precise protection for PV feed circuits, enabling selective coordination with inverters and string combiners, reducing the risk of nuisance trips and equipment damage. Application: Suitable for PV array feeders in commercial rooftops and utility-scale solar installations where consistent trip characteristics matter. Feature: It supports 600 Vac and 250 Vdc voltage ratings, with interrupt ratings up to 25 kAIC at 600 Vac, 65 kAIC at 480 Vac, and 100 kAIC at 240 Vac. Business impact: The broad electrical envelope accommodates both AC side protection and DC PV protection without needing separate devices, simplifying procurement and stocking. Application: Ideal for PV inverters, combiner boxes, and switchgear that operate across mixed AC/DC portfolios. Feature: The unit is specified as without terminals, framed as a JG complete breaker. Business impact: Installation is streamlined, with less wiring complexity and fewer terminal-related failure points, improving reliability and reducing field labor. Application: Fits standard JG frame enclosures in new builds and retrofit projects where fast, low-risk installation is prioritized. Feature: UL 489 certification and Series G classification, combined with the 50/60 Hz frequency rating. Business impact: Regulatory compliance and predictable performance across climates, simplifying panel certification. Application: Control panels, distribution boards, and PV system protection modules require such certifications for code compliance. Feature: The interrupt ratings of 25 kAIC at 600 Vac, 65 kAIC at 480 Vac, and 100 kAIC at 240 Vac provide substantial fault handling headroom. Business impact: Enables safe operation in grids with high short-circuit currents and supports reliable coordination with upstream protection. Application: Essential for utility-scale PV plants and high-demand commercial PV installations.
