FAQs
The JGSDC3250FAG is a three-pole molded case circuit breaker designed for PVGuard solar protection. It uses line and load terminals and metric mounting hardware, enabling straightforward mounting in standard MCCB panels. Plan for 250 A protection, ensure proper conductor sizing for Cu wire, and select a location with adequate airflow for reliable thermal performance.
Key specs include 250 A amperage, voltage ratings of 600 Vac and 250 Vdc, and a T185 trip type in the JG frame. The device is UL 489 certified, three-pole with line and load terminals. These specs support reliable protection for mixed AC/DC PV circuits while enabling predictable coordination and fast fault removal.
This MCCB is ideal for PV solar protection, DC distribution in solar arrays, and industrial protection schemes requiring a robust three-pole protection device. PVGuard integration provides compatibility with solar installations, reduces nuisance tripping, and aligns with standard maintenance practices for utility-scale and commercial PV sites.
The JGSDC3250FAG carries UL 489 certification, a widely recognized standard for molded case circuit breakers. This ensures safety and compliance within typical electrical protection schemes used in PV, industrial, and distribution systems, helping with code conformity and inspection readiness.
Expect improved transformer and inverter protection, reduced downtime due to precise T185 trip coordination, and simpler spares management from a standardized three-pole MCCB in the JG frame. Warranty terms (1 year from installation or 18 months from shipment) add post-install support, enhancing total cost of ownership in renewable-energy deployments.
