Siemens BQD240 is a molded case circuit breaker designed for providing reliable overcurrent and short-circuit protection in industrial and commercial electrical systems. It features a 40A current rating and a 480V AC voltage rating, housed within a compact, durable enclosure measuring 2" x 4.49" x 4.49" (50.8mm x 114mm x 114mm) and weighing 1.1 lb. The breaker is constructed for bolt-on connection with lug terminals and complies with CSA-C22.2 and UL 512 standards, ensuring safe operation in environments from -25°C to 70°C. Its thermal-magnetic protection with long-time and instantaneous (LI) trip functions and a 14kA interrupting rating at 480V makes it suitable for safeguarding branch circuits in Siemens P1 panelboards and similar single-phase applications.
