Siemens LGB2K020B is a molded case circuit breaker designed for providing reliable thermal-magnetic protection against overloads and short circuits in industrial and commercial electrical systems. It features a 20A current rating and a 600V AC voltage rating, housed within a compact GB2 frame measuring 72.9mm x 50mm x 126.7mm (2.87" x 1.969" x 4.988") and weighing 1.852 lb. The breaker is certified to UL, CSA, IEC, and NOM standards and operates effectively across a temperature range of -25°C to 70°C (-13°F to 158°F). Its typical applications include panelboards, switchboards, and motor control centers where its 65kA interrupting capacity at 480V and bolt-on connection for #14 to #10 AWG copper or aluminum wire ensure robust circuit protection.
