The Siemens 5SJ4106-7HG41 is a miniature circuit breaker (MCB) from the 5SJ4 series. It is a single-pole device with a rated operational current of 6A at 30°C and a C-trip characteristic, making it suitable for protecting circuits against overloads and short circuits. The breaker is rated for insulation voltage of 440V AC and supply voltage of 400V AC, with a maximum operating voltage of 240V AC per UL 489 and CSA standards. It has a rated switching capacity of 10kA according to EN 60898 and 15kA according to IEC 60947-2, with a short-circuit breaking capacity of 14kA per UL 1077. The MCB is designed for DIN rail mounting and occupies 1 modular width unit (18mm). It features screw-type terminals accepting conductors from 0.75 to 25 mm² with a maximum tightening torque of 3.5 Nm. The device has a protection class of IP20 (with connected conductors, IP40 in the handle range) and is suitable for overvoltage category III and pollution degree 3. Mechanical service life is 10,000 switching cycles. Dimensions are 110mm height, 18mm width, and 70mm depth, with a net weight of 171g.
The maximum operating voltage is 240 V AC according to UL 489 and CSA C22.2 No. 5-02, and 60 V DC (single channel) or 125 V DC (2-channel).
The rated operational current is 6 A at 30 °C and 40 °C, derating to 5.4 A at 60 °C.
It has a C tripping characteristic.
The rated switching capacity is 10 kA according to EN 60898 and 15 kA according to IEC 60947-2. The short-circuit breaking capacity is 14 kA per UL 1077.
The mechanical service life is 10,000 switching cycles.
The protection class is IP20 with connected conductors, and IP40 in the handle range.
Finely stranded conductors with core end processing from 0.75 mm² to 25 mm² can be connected.
