Siemens CQD180 Circuit Breaker is a 1-pole molded case circuit breaker designed for thermal magnetic overcurrent protection in branch circuits. It is rated for 80A continuous current at 277VAC with a 14kA interrupting capacity at 277V, providing LI (Long-Time and Instantaneous Trip) functions for coordinated fault clearing. The unit features a feed-thru connection, weighs 0.741 lb, and operates within a temperature range of -13 to 158 °F (-25 to 70 °C). This breaker complies with applicable UL and NEMA standards for industrial panelboard and load center installations. Typical applications include lighting, heating, and motor control circuits in commercial and light industrial power distribution systems.
