Siemens HED42B110 is a molded case circuit breaker designed for providing reliable overcurrent and short-circuit protection in commercial and industrial electrical systems. It features a 110A continuous current rating and a 480V AC voltage rating, housed within a compact 125A/ED frame with a thermal-magnetic trip unit for coordinated protection. The breaker is constructed for durability with load side lug connections and is rated for use with copper conductors from 3 AWG to 10 AWG or aluminum from 1/0 AWG to 2 AWG. It complies with industry standards, being UL Listed and HACR rated for heating, air conditioning, and refrigeration equipment. This single-pole, two-pole device is typically applied in Siemens SB switchboards and Sentron panelboards for branch circuit protection where a 42kA interrupting capacity at 480V is required.
