💡 What is a single-pole thermal-magnetic circuit breaker used for in residential load centers? A single-pole thermal-magnetic breaker is the standard device for protecting one hot leg of a house or light commercial circuit from overloads and short circuits. Short intro: It keeps wiring and appliances safe while fitting typical load centers. - Protects individual branch circuits like receptacles, lighting, small heaters, and window AC units - Uses a thermal element for overloads and a magnetic element for short-circuit trips, with a 10 kAIC interrupting rating - Designed to plug into common Q Line/THQL panels and shows easy-to-see trip indication
