Square D QOB115-1021 is a 1-pole, 15A molded case circuit breaker from the QOB Series, designed to provide thermal-magnetic protection for branch circuits. It is rated for 120/240VAC with a 10kAIC interrupting capacity and features a bolt-on mounting style for secure installation in NQOD panelboards. The breaker weighs 5.19 lb, accepts wire sizes from AWG 14 to AWG 8 (Cu/Al), and uses a pressure plate terminal connection for reliable wiring. It is UL Listed and CSA certified, with a temperature rating of -13 to 158°F (-25 to 70°C), and offers LI (Long-Time and Instantaneous) trip functions for overcurrent protection in single-phase industrial applications.
