Siemens HED42B030 is a molded case circuit breaker designed for providing reliable overcurrent and short-circuit protection in industrial electrical systems. It features a 30A current rating and a 480V AC voltage rating, housed within a compact 125A/ED frame with a thermal-magnetic trip unit for long-time and instantaneous (LI) protection functions. The breaker is constructed for durability with load side lug connections, supports a minimum wire size of 12 AWG (Al) or 14 AWG (Cu) and a maximum of 10 AWG, and operates within a temperature range of -25 to 70 °C. It complies with key industry standards including UL 489 and IEC 60947-2, ensuring safety and interoperability. This high-interrupting capacity (42kA at 480V) breaker is typically applied in single-phase systems within SB switchboards and Sentron panelboards for branch circuit protection.
