breakers are essential safety devices that protect electrical circuits from overloads and short circuits. The main difference between SP, TP, TPN, and 4P circuit breakers lies in the number of poles and their applications: SP (Single Pole) for 120V single-phase circuits, TP (Triple Pole) for 240V\/480V three-phase circuits without neutral protection, TPN (Triple Pole + Neutral) for three-phase circuits requiring neutral protection, and 4P (Four Pole) for complete three-phase systems with neutral and ground fault protection. Understanding which circuit breaker to use ensures electrical safety, code compliance, and optimal system performance for your specific application. What Are Circuit Breaker Poles and Why Do They Matter?
