Description
Built to support aging infrastructure, this 800A, 3-pole MCCB features advanced Seltronic technology. The electronic trip unit offers configurable long-time, short-time, and ground fault (LSG) settings. Designed as a substitute for the HMDL3800F, it mounts into existing Cutler-Hammer or Westinghouse Series C panelboards without requiring retrofit kits. With a 65kAIC rating at 240VAC, it handles demanding fault currents safely. A compatible rating plug must be installed for operation.Specifications

Product FAQs
5 answersIs a rating plug required for the HMCGA3800F to operate?
Yes. This Seltronic breaker requires a compatible 8MCG or 8MC series fixed rating plug to establish its continuous current rating. The rating plug is not included and must be installed prior to operation.
Which rating plugs are compatible with the HMCGA3800F circuit breaker?
It accepts Westinghouse or Cutler-Hammer Seltronic rating plugs designed for 800A frames. Common compatible plugs include the 8MCG400, 8MCG500, and 8MC800, which set the breaker to 400A, 500A, or 800A respectively.
What protection features are included in the LSG trip unit?
The solid state electronic trip unit features adjustable Long-Time, Short-Time, and Ground-Fault protection. This allows panel builders to precisely coordinate overcurrent, short circuit, and ground fault responses within the distribution system.
What equipment is the HMCGA3800F designed to fit?
This legacy breaker is engineered for unit mount installation in Eaton Series C panelboards, switchboards, and motor control centers.
Is the HMCGA3800F a current production model?
No. The HMCGA series is a legacy Seltronic molded case circuit breaker originally produced by Westinghouse and later Eaton Cutler-Hammer. When replacing this unit, modern Eaton Series C or Series G equivalents are typically evaluated depending on the existing panel hardware.
