This Siemens 5SJ4316-7HG42 is a 3-pole miniature circuit breaker from the 5SJ4 series. It features a C tripping characteristic and a rated current of 16A, with a switching capacity of 10kA according to EN 60898.
The breaker operates at a rated voltage of 400V AC and has an insulation voltage of 440V AC. It is suitable for installation in environment B regarding EMC.
Designed for DIN rail mounting, this circuit breaker has a mechanical service life of typically 10,000 switching cycles. It is halogen-free, sealable, and silicon-free, making it suitable for various industrial and mechanical engineering applications.
Key electrical specifications include a rated supply voltage of 400V AC at 50Hz, and operating voltage limits up to 277V AC (UL 489) and 125V DC (2-channel UL 489). The power loss per pole in a hot operating state is 2.2W.
Connections are made via combined terminals at the top and bottom, supporting finely stranded conductors with core end processing from 0.75 mm² to 25 mm². The maximum tightening torque for screw terminals is 3.5 N·m. The unit dimensions are 121mm height, 54mm width, and 70mm depth, with an installation depth of 70mm, occupying 3 modular width units.
For AC, maximum operating voltage is 277V per UL 489. For DC, maximum is 60V (single channel) or 125V (2-channel).
Dimensions are 121 mm (H) x 54 mm (W) x 70 mm (D). Mounts on DIN rail.
