"PowerPact™ D-frame electronic trip 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 non-automatic means and to open the circuit automatically on a predetermined overcurrent. The D-frame circuit breakers use an electronic trip system to signal the circuit breaker to open automatically."
