Siemens HED43B030 is a molded case circuit breaker designed for providing reliable overcurrent and short-circuit protection in three-phase electrical systems. It features a 30A current rating and a 480V AC voltage rating, housed within a compact 3" x 6.34" (76.2 mm x 161 mm) frame with a thermal-magnetic trip unit for long-time and instantaneous protection. This HACR-rated and UL-listed breaker is constructed for operation in temperatures from -25°C to 70°C and is engineered for a high interrupting capacity of 42kA at 480V. It is typically applied in industrial and commercial power distribution within SB switchboards and Sentron panelboards, utilizing load-side lugs for secure connections with copper or aluminum conductors ranging from AWG 10 to 1/0.
