FAQs
MDL3800A13S02 uses a Series C, Frame J-K design, which aligns with Eaton Series C enclosures and common MCCB mounting footprints. For retrofit projects, verify panel dimensions, available lugs or terminals, and space for 18.6 in depth, 11.1 in width, and 8.3 in height. Review time-current curves to ensure proper coordination with upstream protection and downstream devices.
Key specs include an 800 A amperage rating and three-pole configuration, with a Frame J-K and Series C designation. These determine protection scope, pick-up current, and trip characteristics. The 800 A rating supports high-load feeders, while the three-pole design protects all phases in 3-phase systems. For accurate coordination, consult the Series C time-current curves and select appropriate breaker settings.
Yes, for defined motor protection within its rated 800 A capacity, MDL3800A13S02 can protect motors and feeders in 3-phase systems. To handle inrush, use proper coordination with upstream protection and motor starters, and leverage the provided time-current curves to ensure proper delay characteristics. Consider accessories like motor operators if motor control requires plug-in solutions.
The product family includes UL-listed, 100%-rated protection, which is critical for reliable operation under full-load conditions. Depending on the market, CE conformity and IP ratings may apply; verify regional requirements with the manufacturer and ensure the specific model meets your enclosure, installation, and safety standards.
MDL3800A13S02 ships with a clear warranty (Eaton policy 25-000), typically one year from installation or eighteen months from shipment, whichever comes first. Maintenance benefits include modular, serviceable components and compatibility with a broad ecosystem of lugs, terminations, and accessories. This translates to predictable lifecycle costs, straightforward spare-part sourcing, and minimized downtime during maintenance or retrofits.
