The Siemens 5SJ4118-7HG42 is a 1-pole miniature circuit breaker (MCB) from the 5SJ4 series, designed for reliable protection in industrial and mechanical engineering applications. This device offers a 15A operational current rating and a C-trip characteristic, suitable for handling moderate inrush currents.
With a switching capacity of 10kA according to EN 60898 and 15kA according to IEC 60947-2, this circuit breaker provides robust protection against overcurrents and short circuits. It operates on AC voltages up to 277V and DC voltages up to 60V (single channel) or 125V (2-channel), with a rated supply voltage of 400V AC at 50Hz.
The breaker features a DIN rail mounting type and a compact design with dimensions of 121mm height, 18mm width, and 70mm depth. It includes touch protection and combined terminals for convenient and safe connections. The device is also halogen-free, sealable, and silicon-free, contributing to its suitability for various environments.
The maximum operating voltage is 277V AC (per UL 489/CSA C22.2), 60V DC single channel, and 125V DC 2-channel.
The tripping characteristic is C.
The rated operational current is 15A at 30°C and 40°C, with derating to 14.6A at 45°C, 14.1A at 50°C, 13.6A at 55°C, and 13.2A at 60°C.
The breaking capacity is 10kA according to EN 60898 and 15kA according to IEC 60947-2.
The overvoltage category is 3 and the degree of pollution is 3.
The protection class is IP20, with IP40 in the handle range when conductors are connected.
Height 121 mm, width 18 mm, depth 70 mm. Mounts on standard DIN rail.
