3-Pole Circuit Breakers

3-Pole Circuit Breakers — New & Used

3-pole circuit breakers protect three-phase electrical circuits by interrupting all three phases simultaneously in case of overloads, short circuits, or ground-fault conditions — safeguarding motors, control systems, and equipment. They are essential for safe, reliable operation of three-phase systems and multi-phase loads.
