Siemens 5SJ4106-7HG41 Molded Case Circuit Breaker

Siemens 5SJ4106-7HG41 is a 1-pole miniature circuit breaker in the SENTRON 5SJ4 family, delivering thermal‑magnetic overcurrent protection for small distribution circuits at 240 V AC with a 6 A rated current and a short‑circuit breaking capacity of 14 kA (UL 489). It uses a C‑trip characteristic for selective protection of branches and equipment, and it occupies a 1TE width with a depth of 70 mm in standard enclosures. The device has an insulation voltage Ui of 440 V and supports AC supply voltages up to 400 V, with DC ratings of up to 60 V for single‑channel configurations. Rated for around 10,000 mechanical operating cycles, it provides IP20 protection with connected conductors (IP40 in the handle range) and is UL 489 listed. Commonly used to protect branch circuits, lighting runs, and small motor feeders in commercial and light‑industrial panels, this Siemens 5SJ4 device is designed for reliable, code‑compliant circuit protection in switchgear and distribution boards.
