Siemens HED41B020 is a molded case circuit breaker designed for reliable overcurrent protection in industrial and commercial electrical systems. It provides a 20A current rating and a 277V voltage rating for single-phase applications, featuring a compact design measuring 1" x 6.35" and a weight of 0.851 lb. The breaker is constructed with a thermal-magnetic trip unit for combined long-time and instantaneous (LI) protection and is built to operate within a temperature range of -25°C to 70°C. It complies with key industry standards including UL 489 and IEC 60947-2, ensuring safety and interoperability. This high-interrupting capacity (65kA @ 277V) breaker is typically applied in Siemens Sentron panelboards and SB switchboards for branch circuit protection.
