Siemens QJ2B080H is a molded case circuit breaker from the QJH Series, designed to provide overcurrent protection through its LI (Long-Time and Instantaneous) trip functions. This 2-pole, 1-phase unit is rated for 80A at 240V AC, with a high interrupting capacity of 42kA at 240V, and features a bolt-on connection for secure installation. The breaker employs thermal-magnetic protection, combining a bimetallic element for long-time overloads and a magnetic coil for instantaneous short circuits, housed in a compact molded case weighing 3 lb. It is built to meet industry standards for industrial applications, ensuring reliable performance in demanding environments. Typical uses include protecting branch circuits in commercial and industrial power distribution panels, motor control centers, and switchboards where robust overcurrent protection is required.
