Product FAQs
5 answersDoes the MC3800 breaker require a rating plug?
Yes, this Seltronic electronic trip breaker requires a compatible rating plug to operate. The rating plug sets the continuous current rating and must be installed for the breaker to function properly.
Is the Westinghouse MC3800 still manufactured?
Westinghouse circuit breakers are no longer manufactured under the original brand name since Eaton acquired the product line in 1994. Eaton continues to support these legacy MC frames, and exact drop-in replacements are available for existing switchboards and motor control centers.
What does the LS trip function code mean on the MC3800?
The LS designation indicates that the Seltronic solid-state trip unit features adjustable Long-Time and Short-Time protection. This allows electricians to fine-tune the breaker response to overloads and short circuits for better system coordination.
What types of equipment is the MC3800 designed to fit?
This bolt-on MC frame breaker is designed as a direct replacement for aging Westinghouse switchboards, motor control centers, and panelboards without the need for retrofitting adapters.
What is a Seltronic circuit breaker?
Seltronic is the legacy Westinghouse trade name for their early solid-state electronic trip units. Unlike standard thermal-magnetic breakers, Seltronic units use electronic circuitry and interchangeable rating plugs to provide highly accurate and adjustable overcurrent protection.
