FAQs
The JGS2100FAG is a two-pole MCCB built on the JG frame within the Series G family, featuring line and load terminals for straightforward wiring. Its compact 3.44 in depth, 7 in height, and 4.13 in width fit dense panel environments, while the 6 lb weight supports easy handling during field installation and retrofit projects.
This MCCB uses fixed thermal protection and an adjustable magnetic trip (T185) to tailor short-circuit response. Adjusting the magnetic trip is recommended when coordinating with upstream protective devices or when protecting equipment with varying inrush or fault current profiles to avoid nuisance trips while maintaining safety margins.
Yes. With 100 A rating, 600 Vac / 250 Vdc voltage capability, and interrupt ratings up to 85 kAIC at 240 Vac, the device supports selective coordination and robust fault protection in automation panels. UL Listed, CSA Certified, and IEC Rated certifications further reinforce reliability and regulatory compliance across manufacturing sites.
JGS2100FAG carries UL Listed, CSA Certified, IEC Rated, and CE Marked certifications. When selecting enclosures, ensure the panel enclosure material and ingress protection align with 600 Vac operation and the specific environment, and verify that the enclosure supports the Series G MCCB’s torque and wiring requirements for safe, compliant installations.
Maintenance is typically limited to periodic inspection of connections and trip settings per the service policy; Eaton provides a one-year warranty (or 18 months from shipment). The device’s high interrupt ratings and durable field-reliable design reduce downtime, improve predictability of protection, and lower lifecycle costs by minimizing unexpected equipment failures in critical lines.
