5SJ4101-7HG41

The Siemens 5SJ4101-7HG41 is a miniature circuit breaker (MCB) from the 5SJ4 series. It is a single-pole device with a rated current of 1A and a C tripping characteristic, suitable for protecting circuits against overloads and short circuits. The breaker is rated for 240V AC operation under UL 489 and CSA C22.2 No. 5-02, and can handle 60V DC for single-channel or 125V DC for two-channel configurations.

Its breaking capacity is 10 kA according to EN 60898 and 15 kA per IEC 60947-2, with a short-circuit breaking capacity of 14 kA at AC under UL 1077. The insulation voltage is 440V AC and supply voltage 400V AC at 50 Hz. Power loss is 1.7W per pole in hot operating state.

The MCB is designed for DIN rail mounting with a width of 18 mm (1 modular unit) and dimensions of 110 mm height, 70 mm depth. It accepts conductor cross-sections from 0.75 mm² to 25 mm² with a maximum tightening torque of 3.5 Nm. Protection class IP20 with connected conductors and IP40 in the handle range. It is halogen-free, silicon-free, sealable, and touch protected. Overvoltage category III and pollution degree 3. Mechanical service life is 10,000 switching cycles.
