FAQs
The JGHDC3150FAW is a three-pole, 150 A MCCB in the JG frame rated for 600 Vac and 250 Vdc. Install in an appropriate enclosure with terminals removed as specified. Route conductors per the panel manufacturer’s guidelines, torque terminals to the recommended values if terminated externally, and coordinate with upstream protection and inverters to prevent nuisance trips.
JG frame three-pole MCCBs like JGHDC3150FAW are designed for PV environments with DC ratings up to 250 Vdc. Ensure panel compatibility with the JG frame size, verify trip type T185 settings for your fault current, and confirm terminations configuration aligns with your enclosure and busbar layout to avoid miswiring or improper protection coordination.
Yes, the JGHDC3150FAW carries UL 489 certification, indicating meeting recognized safety and performance standards for molded case circuit breakers. This supports compliance in many regions and simplifies integration with industrial panels, solar disconnects, and PV system protection schemes that rely on UL-based safety validation.
The product is covered by Eaton’s warranty policy 25-000, which offers one year from installation or eighteen months from shipment, whichever occurs first. This provides protection against manufacturing defects and contributes to total cost of ownership by reducing maintenance risk during initial installation and deployment.
The unit weighs 6.5 lb and has dimensions of 4.13 in by 4.13 in with a depth of 3.57 in. Plan for a compact footprint in PV inverters and distribution panels, allowing for safe clearance and adequate ventilation. With no terminals, consider internal routing, mounting provisions, and compatibility with existing MCCB mounting rails in your enclosure.
