Product FAQs
6 answersWhat equipment is the MDLB3800FT33W designed to fit?
This Series C M-Frame breaker is designed for installation in Eaton and Cutler-Hammer panelboards, switchboards, and motor control centers.
Can the trip unit on the MDLB3800FT33W be swapped out in the field?
No. The MDLB3800FT33W is a factory-sealed breaker equipped with a non-interchangeable Digitrip 310+ electronic trip unit.
Can the MDLB3800FT33W be reverse fed?
Yes. Because it is a factory-sealed breaker with a non-interchangeable trip unit, Eaton permits the MDLB3800FT33W to be installed in reverse feed applications.
What protection settings are adjustable on the MDLB3800FT33W?
The Digitrip 310+ electronic trip unit allows users to adjust both Long-Time (L) and Short-Time (S) pickup and delay settings to coordinate with other protective devices in the system.
What is the difference between an MDLB and a standard MDL breaker?
MDLB breakers, including the MDLB3800FT33W, are factory-sealed units with non-interchangeable trip units. Standard MDL breakers are designed to accept field-interchangeable trip units.
What does the "FT" in the MDLB3800FT33W catalog number indicate?
The "FT" designates a feed-thru connection type, meaning the breaker is configured for standard unit mount applications rather than plug-in or drawout installations.
