A 1 pole circuit breaker is designed to protect electrical circuits from damage caused by overloads or short circuits. These breakers disconnect power flow automatically when an electrical fault is detected, isolating the affected circuit before damage can spread.
Single-pole breakers protect a single 120V circuit, which is the standard configuration for branch circuits, lighting circuits, and small appliance circuits in residential panels and light commercial installations. This is the key distinction from 2 pole breakers, which are designed for 240V double-phase circuits.

If you’re sourcing by panel compatibility or specific catalog number, contact our team, and we’ll locate the right unit fast.
How do I know if I need a 1 pole or 2 pole circuit breaker?
If the circuit runs on 120V, such as branch circuits, lighting, or small appliances, you need a 1 pole breaker. If the circuit runs on 240V, like electric dryers, HVAC units, and water heaters, you need a 2 pole breaker. Match the breaker’s pole count to the voltage and phase configuration of the circuit being protected.
