Siemens Industry, Inc. 5SN9 NG 2-Pole Circuit Breaker

Siemens Industry's 5SN9 NG 2-Pole Circuit Breaker is a compact, industrial-grade protective device rated for 10 A and up to 415 VAC, designed to interrupt both conductors of a two-pole circuit with a common trip when an overload or fault occurs. As part of the 5SN9 NG family, this molded-case breaker provides dependable overload and short-circuit protection for power distribution in panels, control cabinets, and industrial equipment. The 2-pole configuration guarantees simultaneous disconnection of both conductors, which enhances safety and simplifies compliance in dual-wire circuits. With a 10 A rated current, it is well suited to protect smaller loads and motor-control circuits where precise current limitation is required without oversizing the protective device. Typical applications include safeguarding branch circuits in manufacturing lines, packaging equipment, conveyors, and other plant automation equipment, as well as protection for compact power distribution enclosures in industrial environments. The model’s specific electrical characteristics (voltage rating, current rating) and its place within Siemens’ NG series make it compatible with Siemens-based control systems and panels that specify 5SN9 NG devices for two-pole protection at low to moderate current levels.
