FAQs
Yes. The JGEDC3150FAG is a three-pole molded case circuit breaker designed for PV protection with line and load terminals, supporting 600 Vac and 250 Vdc. Its JG frame and 150 A rating make it suitable for DC distribution panels and PV combiner boxes, simplifying assembly and ensuring reliable fault interruption in solar installations.
The device uses fixed thermal protection with an adjustable magnetic trip (Trip Type T185), allowing field coordination with other protection devices. This combination helps prevent nuisance trips during normal DC transients while delivering fast response to overcurrent events, which is critical for protecting PV inverters and DC wiring in solar applications.
Yes. The JGEDC3150FAG carries UL 489 certification, which is the standard for molded case circuit breakers, and is designed for DC PV protection. This compliance supports regulatory readiness, simplifies inspections, and provides confidence when integrating into commercial and industrial PV projects.
The breaker provides a 35 kAIC interrupt rating at 600 Vac, enabling rapid interruption of high-energy fault currents in DC PV systems. This capability protects upstream devices, reduces arc energy in DC circuits, and minimizes the risk of thermal damage in PV arrays and associated equipment.
Use the JGEDC3150FAG in PV arrays, DC distribution panels, or line-load protective segments where robust DC protection is required. Its three-pole configuration, 150 A rating, and UL 489 certification align with both safety and performance demands for rooftop and utility-scale solar deployments, while maintaining a compact footprint for easier cabinet integration.
