Square D QBL32150 is a molded case circuit breaker designed for providing reliable overcurrent and short-circuit protection in three-phase industrial power distribution systems. It features a 150A current rating and a 240V AC voltage rating, housed within a compact 250A frame with bolt-on connections and line/load lugs for secure installation. The breaker's thermal-magnetic trip unit provides both long-time and instantaneous protection, and its robust construction allows operation across a wide temperature range from -25°C to 70°C (-13°F to 158°F). It complies with UL, CSA, NEMA, and NOM standards, making it suitable for use in panelboards, switchboards, and industrial control panels where a 10kA interrupting rating at 240V is required.
