Introduction to Automatic Reset Circuit Breakers #
Automatic reset circuit breakers are essential unipolar, free-cycle trip protection devices designed to safeguard electrical circuits. When connected in series with a motor or other equipment, these breakers utilize a bimetallic sheet that thermally deforms in response to current overloads, instantly interrupting the current flow to protect the circuit.
