FAQs
For metric-panel installations, mount the JGU4160AAG using the provided metric mounting hardware. Connect line and load conductors to the four-pole terminals, ensuring correct phase alignment. Verify the neutral pole configuration aligns with the system design, noting the 0% protected neutral pole feature. With the adjustable thermal-magnetic trip, set the trip curves to match motor and load profiles to optimize protection without nuisance tripping.
The device is rated for 160 A and 600 Vac with 50/60 Hz operation. It offers interrupt ratings of 50 kAIC at 600 Vac, 200 kAIC at 240 Vac, and 150 kAIC at 480 Vac, providing robust short-circuit protection for industrial feeders and control panels. The four-pole design supports three-phase protection with a common trip.
Yes. The four-pole design and configurable thermal-magnetic trip are well-suited for three-phase motor protection in panel distributes. While it provides strong short-circuit protection and coordination, confirm your panel’s wiring and neutral handling align with the device’s 0% protected neutral pole feature and the system’s neutral requirements.
The JGU4160AAG carries CE Marked compliance and IEC rated certification, and is UL Listed and CSA Certified as part of its documented credentials. Note that the product listing also notes Not UL rated in its special features, so verify which U.S. or global compliance requirements your implementation mandates for end-use validation.
Eaton provides a warranty under Selling Policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first. This supports commissioning and initial operation.
