Description
Part of the Sentron family, this 45A unit-mount molded case circuit breaker is configured for individual enclosures and switchboard mounting. It comes factory-equipped with both line and load lugs for immediate wire termination. While this specific ED4 frame model has been superseded by the 3VA5145-4ED36-0AA0, it remains a critical exact-match replacement for existing industrial infrastructure requiring 65kAIC at 240VAC.Specifications
