Siemens 5SJ4211-7HG42 Two-Pole Circuit Breaker

Siemens 5SJ4211-7HG42 is a two-pole miniature circuit breaker rated at 5 A, designed for 480Y/277 V AC distribution and built to interrupt up to 10 kA. This 2-pole device uses a Type C trip characteristic for general-purpose protection, suitable for loads with moderate inrush such as lighting and receptacle circuits in commercial or light industrial panelboards. It is UL 489-listed for 480Y/277 V operation, guaranteeing compatibility with standard distribution equipment, and belongs to the Siemens 5SJ4 family of LV miniature breakers. The 5SJ4211-7HG42 provides simultaneous disconnection of both supply lines in fault conditions, making it appropriate for panelboards and switchgear where reliable overcurrent protection is required on 480Y/277 V systems.
