Part of the GE Q-Line family, the THHQL2120 delivers 20 amps of thermal-magnetic protection. This 2-pole breaker utilizes a trip-free mechanism that prevents contacts from being held closed during an overcurrent event. The breaker mounts into GE A-Series panelboards, PowerMark Gold load centers, and ABB ReliaHome panels. Its plug-on design allows for quick integration into compatible busbars. With a 22 kAIC rating, it provides robust fault protection and carries an SWD classification.
