FAQs

The JGU3250AAG uses the Series G’s JG frame with metric mounting hardware and line/load terminals for straightforward integration into standard MCCB panels. Its compact 4.13 x 4.13 inch footprint and 3.57 inch depth help fit denser panels, while three‑pole construction ensures consistent disconnect and protection across feeder circuits.
Key specifications include a 250 A rating, 600 Vac, and a trip type that is both adjustable thermal and adjustable magnetic. The device operates at 50 to 60 Hz, with interrupt ratings of 50 kAIC at 600 Vac, 150 kAIC at 480 Vac, and 200 kAIC at 240 Vac, enabling robust fault tolerance across varying systems.
Ideal for industrial control panels, motor control centers, and process lines where reliable protection and coordination are critical. It suits manufacturing, packaging, and automation environments requiring precise trip settings, international compliance, and compact form factors for space‑constrained installations.
This device is IEC rated, CSA certified, and UL listed, with CE marking. These certifications support global deployment and ensure alignment with common regional electrical codes, product safety standards, and performance requirements.
With a robust Series G design, adjustable trip settings, and high interrupt ratings, the MCCB offers long service life and reduced downtime from nuisance trips. The standard warranty (one year from installation or 18 months from shipment) supports risk mitigation during initial commissioning and early field use.
