Siemens 5SJ4130-7HG41 Circuit Breaker

Siemens 5SJ4130-7HG41 is a 1-pole miniature circuit breaker from the Siemens 5SJ4 family, designed to interrupt fault currents in low-voltage distribution panels. It is rated for 240 V AC and 30 A, with a C-type trip curve suitable for applications with moderate inrush or short-term overloads. The device offers a short-circuit breaking capacity of 14 kA at 240 V, and is UL 489 listed, aligning with North American electrical safety standards. Its physical envelope measures 110 mm in height, 18 mm in width, and 70 mm in depth, corresponding to a mounting depth of 70 mm in typical panel spaces. The 5SJ4130-7HG41 model, identified by its 7HG41 designation, specifies its particular form factor within the 5SJ4 range, including one-pole configuration and a current rating of 30 A. This breaker is intended for protection of individual circuits against overloads and short circuits in residential, commercial, and light industrial installations, offering compact size and straightforward installation for efficient panel protection.
