Section 1—General Information
Introduction
H-frame and J-frame molded case circuit breakers are designed to protect electrical systems from
damage caused by overloads and short circuits. All circuit breakers are designed to open and close a
circuit by nonautomatic means and to open the circuit automatically on a predetermined overcurrent.
Features and Benefits
The H- and J-frame modular platform provides many options for accessories, configurations, and
actuation. H- and J-frame circuit breakers (15–250 A) and motor-circuit protectors (30–250 A) are
designed to use common accessories. Some of the key features are defined below:
Common Design Envelope
Both the H-frame and J-frame circuit breakers feature common mounting holes, handle locations and
trim dimensions.
