1-Pole Circuit Breakers — New & Used | Surplus
Browse new and used 1-pole circuit breakers for 120 V single-phase circuits. Perfect for lighting, outlets, small motors, panels, and electrical maintenance.
A single-pole circuit breaker covers one wire and takes up one place in the panel, while 2-pole breakers cover two wires and take up two places, and so on. What is a Tandem Breaker? In addition to understanding the difference between single and 2-pole circuit breakers, you should be familiar with what sets tandem breakers apart.
Double-pole breakers are easy to spot in your breaker box because they feature side-by-side, interlinked switches. These breakers can control two wires simultaneously. They're necessary for appliances like washers and dryers that require large amounts of electricity. For more information, see our guide called Circuit Breaker 101.
AFCI breakers: Arc fault circuit interrupters, or AFCI breakers, protect against excessive electrical arcing. A small amount of arcing often happens when a light switch is flipped, but any larger sparks caused by faults will trip the breaker to reduce the risks of fire. Combination AFCI breakers are also available.
