These THQB and THHQB series miniature circuit breakers are bolted into place in panelboards and load centers, so they're more stable than plug-in or unit-mount circuit breakers. They interrupt currents when faults are detected in the circuit. These breakers connect to the power supply through bus bars, which eliminates the need to pigtail wires and helps organize the panelboard or load center. They're UL listed for use in HACR (heating, air conditioning, and refrigeration) applications. This listing is for each.
