Siemens ED22B050 is a molded case circuit breaker designed for providing reliable overcurrent and short-circuit protection in commercial and industrial electrical systems. It features a 50A current rating and a 240V AC voltage rating, housed within a compact 2-inch by 6.34-inch (50.8 mm x 161 mm) frame with a thermal-magnetic trip unit for long-time and instantaneous (LI) protection functions. This standard, two-pole breaker is constructed for lug-in panelboard connection with load-side lugs, supports a minimum wire size of 10 AWG to a maximum of 1/0 AWG, and operates reliably across a temperature range of -25 to 70 °C. It complies with UL standards and is HACR rated for heating, air conditioning, and refrigeration equipment, offering a 10kA interrupting capacity at 240V for effective fault protection. Typical applications include integration into Siemens SB switchboards and Sentron series panelboards for branch circuit protection in single-phase systems.
