Product FAQs
7 answersWhat type of trip unit is installed in the HMC3800F?
This circuit breaker features a Seltronic Mark 75 solid-state electronic trip unit configured with Long-Time and Short-Time (LS) protection functions.
Does the HMC3800F come ready to install, or does it require additional components?
The HMC3800F is provided as a frame only. A compatible Seltronic Mark 75 rating plug, such as the 8MC800 for 800-amp applications, and the appropriate terminal lugs must be installed for operation.
What is the maximum short-circuit interrupting rating (AIC) for this breaker?
While rated for up to 600V systems, the interrupting capacity scales by voltage. It provides 65 kAIC at 240V, 50 kAIC at 480V, and 25 kAIC at 600V.
What is the direct replacement for the legacy HMC3800F?
Because the legacy MC-frame is no longer in active production, Eaton recommends upgrading to the modern Series C MD-frame equivalent. The direct factory cross-reference is the MDL3800F frame paired with an MES3800LS trip unit.
What mounting style does this circuit breaker use?
The HMC3800F utilizes a bolt-on mounting configuration, which is standard for legacy Westinghouse and Cutler-Hammer industrial panelboards and switchgear designed for the MC-frame footprint.
Can the HMC3800F be utilized in reverse-feed applications?
Yes, Eaton and Cutler-Hammer documentation indicates that standard MC-frame and HMC-frame breakers are suitable for reverse-feed applications.
What does the H in the HMC3800F catalog number indicate?
The H designates this as a high-interrupting capacity breaker. It provides a higher fault current rating compared to the standard MC3800F frame, making it suitable for systems with higher available fault currents.
