Typical L-Frame Circuit Breaker
Product Description
■ All Cutler-Hammer L-Frame Circuit
Breakers by Eaton Corporation are
HACR rated.
■ L-Frame circuit breakers are available
as individual components (Frame,
Trip Unit, Terminals), or factory
assembled complete breakers.
■ L-Frame circuit breakers with
non-interchangeable trip units
are suitable for reverse feed use.
■ CE marked.
