Abstract
A molded case circuit breaker has control terminals mounted on the front of the breaker and accessible from the front. A transparent plexiglass cover is positioned over the terminals to prevent inadvertent contact with the terminals and an opening is provided in the side of the casing for the egress of the control wires. With the control terminals on the front of the circuit breaker, an inspection can be performed without disconnecting power from the breaker.
