FAQs

Yes. The JGU4200FAG uses metric mounting hardware and line/load terminals within a four-pole JG frame, enabling straightforward drop-in replacements in many standard MCC panels. Its compact footprint (3.57 in depth, 5.34 in height and width) fits space-constrained enclosures while maintaining proper clearance and wiring practices for reliable protection.
Key performance specs include a 200 A amperage rating, 600 Vac voltage rating, four poles, and a T185 trip type. Interrupt ratings reach 200 kAIC at 240 Vac, 150 kAIC at 480 Vac, and 50 kAIC at 600 Vac. The device operates at 50 to 60 Hz and uses fixed thermal with adjustable magnetic trip for precise coordination in industrial circuits.
The JGU4200FAG carries CE Marked, UL Listed, IEC Rated, and CSA Certified credentials, providing robust regulatory acceptance in global markets. These certifications support safe operation, standardization across panels, and smoother eligibility for inspections and customer specifications in diverse regions.
80% rated operation means the breaker is suitable for continuous service up to 80% of its rated current under certain conditions. This headroom improves energy management, reduces nuisance trips during normal motor starts, and helps designers balance protection margins with efficiency in larger MCC or control panels.
Maintenance is straightforward due to fixed thermal and adjustable magnetic trip (T185), with readily available Eaton parts and service centers. The unit’s strong interrupt ratings, combined with certifications, reduce downtime and support longer service intervals. These factors contribute to lower lifecycle costs and a faster return on investment for industrial facilities.
