Siemens NGB2B050L is a molded case circuit breaker designed for providing reliable overcurrent and short-circuit protection in industrial electrical systems. It features a 50A current rating and a 600V AC voltage rating, housed within a compact GG frame with a bolt-on connection for secure installation. This two-pole, single-phase breaker utilizes a thermal-magnetic trip mechanism for both long-time delay and instantaneous protection, ensuring compliance with UL and IEC standards. Its robust construction allows for operation in temperatures ranging from -13°F to 158°F (-25°C to 70°C) and it is engineered for an interrupting capacity of 25kA at 480V, making it suitable for panelboards, switchboards, and motor control centers.
