FAQs

Yes. The JGS4250NNW03 is designed for Series G frame integration and supports backplate configurations noted in Eaton documentation (68C2697H02). When retrofitting or interfacing with existing panels, verify backplate fit and UL compatibility to ensure proper mounting, clearance, and safe terminal access during wiring and maintenance.
The interrupt ratings are 18 kAIC at 600 Vac, with higher ratings at lower voltages (40 kAIC at 415 Vac, 35 kAIC at 480 Vac, and 85 kAIC at 240 Vac). This enables a wide fault current handling range suitable for diverse industrial feeders and insulates downstream equipment from short‑circuit faults.
This four‑pole, 250 A 600 Vac MCCB is ideal for power distribution panels, machine feeders, and control panels in manufacturing and process environments. Its Series G frame and walking beam interlock support precise protection coordination, easy maintenance, and robust fault isolation in mid‑ to large‑size installations.
The device is UL Listed, IEC Rated, CSA Certified, and CE Marked. These certifications confirm compliance with US, Canadian, and international electrical safety standards, facilitating global procurement, cross‑border installation, and streamlined regulatory approval for multi‑site operations.
Eaton provides a one‑year warranty from installation or eighteen months from shipment, whichever occurs first. Catalog notes advise backplate modification (68C2697H02) while retaining UL. Plan for field wiring without terminals, ensure proper panel clearances, and reference provided application notes to optimize installation and ongoing service.
