Product FAQs
6 answersCan the Eaton MCG3800F replace older Westinghouse or Cutler-Hammer MC frame breakers?
Yes, Eaton acquired the Westinghouse distribution equipment line and integrated it with Cutler-Hammer. The MCG3800F is backward compatible and serves as a direct replacement for legacy Westinghouse and Cutler-Hammer MC frame breakers in existing motor control centers and panelboards.
What frame family does the MCG3800F belong to?
It is part of the legacy Mark 75 Seltronic family, specifically the MC frame group. This frame is commonly found in older industrial installations requiring high-capacity circuit protection.
Does the MCG3800F circuit breaker require a rating plug to operate?
Yes, this breaker utilizes an electronic trip unit that requires a compatible rating plug to establish the continuous ampere rating. The plug must be installed for the breaker to function correctly and protect the circuit.
What does the LSG trip function on the MCG3800F include?
The LSG electronic trip unit provides adjustable protection for Long-Time, Short-Time, and Ground Fault conditions. This allows for precise coordination with other protective devices in your electrical system.
Are line and load lugs included with the MCG3800F?
This breaker is typically supplied without terminals as a standard configuration. If you are not reusing existing hardware, you will need to verify if a separate lug kit is required for your specific wire size and material.
Does the MCG3800F provide built-in ground fault protection?
Yes, the G in the LSG trip function indicates that this breaker features integrated ground fault sensing. It is designed to detect and trip during low-level ground faults, adding an extra layer of equipment protection.
