FAQs
Yes, JGEDC3070FAW uses the JG frame, part of the Series G/JG family, and is specified as without terminals. This simplifies panel wiring and supports clean integration in Eaton MCCB architectures, reducing terminal clutter and enabling straightforward mounting in standard enclosures.
It is a 70A device rated for 600 Vac and 250 Vdc, with trip type T185. Interruption ratings are 65 kAIC at 240 Vac, 25 kAIC at 480 Vac, and 18 kAIC at 600 Vac, suitable for a broad range of PV and AC protection scenarios.
This three-pole MCCB is ideal for PV array protection with common-mode AC/DC protection needs, including string inverters and distribution panels in commercial solar installations, where a single, UL 489-certified device can protect both DC and AC circuits.
The JGEDC3070FAW carries UL 489 certification, signaling compliance with MCCB protection standards for electrical equipment. This is critical for safe operation in PV systems and helps ensure regulatory acceptance in professional solar installations.
The product carries Eaton’s standard warranty policy (one year from installation or 18 months from shipment, whichever occurs first). Its compact, terminal-free design reduces service complexity, lowers spare parts variety, and can shorten maintenance cycles, contributing to lower total cost of ownership.
