FAQs
Yes. The JGU4150FAG uses metric mounting hardware and line/load terminals, designed to drop into standard four-pole MCCB slots. Its dimensions (3.57 in L, 5.34 in W, 5.34 in H) and 8 lb weight support straightforward retrofit into most control panels and switchgear, helping minimize panel redesigns during upgrades.
The breaker features fixed thermal protection with an adjustable magnetic trip (T185). This allows you to coordinate protection with motor inrush and starting currents. For typical motors, set the magnetic trip to align with motor stall and peak load conditions to prevent nuisance trips while ensuring rapid shutdown during faults.
Ideal for motor control centers, control panels, and machine wiring in manufacturing lines. The four-pole design is well-suited for three-phase systems, and the 150 A, 600 VAC rating supports robust protection for feeders, conveyors, and automated machinery in process environments.
The JGU4150FAG is UL Listed, CSA Certified, and IEC Rated, with CE marking. These certifications support global deployment across compliance regimes, simplify documentation for audits, and facilitate cross-border panel builds and maintenance in international facilities.
Warranty follows Eaton’s policy: 1 year from installation or 18 months from shipment, whichever occurs first. Eaton also provides service centers and distributor support to ensure availability of replacement parts, replacement units, and technical assistance for ongoing operations and ROI improvements.
