The Siemens 5SJ4111-8HG41 is a single-pole miniature circuit breaker designed for reliable circuit protection in industrial and mechanical engineering applications. It operates with a rated current of 5A and offers a significant switching capacity of 10kA according to EN 60898 and 15kA according to IEC 60947-2.
This circuit breaker features a D-trip characteristic, making it suitable for applications with high inrush currents. It is designed for AC/DC voltage and has an operating voltage of up to 240V AC according to UL 489 and CSA C22.2 No. 5-02, and up to 60V DC. The device offers a breaking capacity of 14kA at AC according to UL 1077 and CSA C22.2 No.235.
Constructed with halogen-free materials, the 5SJ4111-8HG41 ensures environmental safety. It has a protection class of IP20 with connected conductors and IP40 in the handle range. The mechanical design includes a width of 18mm and a depth of 70mm, fitting standard mounting rails. It supports conductor cross-sections from 0.75 mm² to 25 mm² with core end processing, and has a maximum tightening torque of 3.5 N·m for screw-type terminals.
At AC (UL 489): 240V maximum; at DC: 60V maximum (single channel) or 125V (2-channel).
