FAQs
The JGS3150FAGA1 uses the JG frame and is designed as a complete three-pole molded-case breaker with line and load terminals. It supports Series G configurations and is compatible with Series G plug-in adapters, enabling flexible panel layouts and straightforward retrofits in existing control panels.
T185 indicates a thermal-magnetic trip characteristic with adjustable magnetic protection. It provides fixed thermal protection with an adjustable magnetic trip setting to tailor short-circuit response, reducing nuisance trips while ensuring reliable protection for motor loads and feeders in 150 A, 600 Vac circuits.
Interrupt ratings are 85 kAIC at 240 Vac, 35 kAIC at 480 Vac, and 18 kAIC at 600 Vac. These ratings influence selective coordination by providing higher fault- current withstand at lower voltages, enabling safer cascading protection in panels, and helping engineers design safe, reliable protection schemes for mixed loads.
Yes, the JGS3150FAGA1 is UL Listed, ensuring conformance to recognized safety standards. When installing, ensure correct line/load orientation, proper torque on terminals, and alignment with Series G accessories. Use the right-pigtail auxiliary switch as required and verify compatibility with panel bus configurations to maintain proper protection coordination.
The Series G MCCB provides durable protection with a fixed thermal and adjustable magnetic trip, reducing unplanned outages and extending panel life. Improved coordination minimizes downstream faults, lowering maintenance and energy losses. The UL listing and modular accessories support quicker commissioning and easier future upgrades, delivering long-term cost savings in retrofit or new-build projects.
