The Siemens 5SJ3116-7 is a 1-pole miniature circuit breaker from the SENTRON 5SJ3 series, rated 16 A with a C tripping characteristic at 240 V AC, 50 Hz.
Mounts on standard DIN rail in any orientation — the mounting position is unrestricted. Overvoltage category 3 and energy limiting class 3 confirm it is designed for fixed-installation distribution boards, not portable equipment.
The only difference is the current rating: 5SJ3116-7 is 16 A, while 5SJ3140-7 is 40 A. Both are 1-pole, C-curve, 240 V AC, 50 Hz, same 70 mm depth, same IP20. If your panel was specified around the 40 A version, the 16 A will not carry the load — you need the 40 A variant. But the physical footprint and wiring are identical, so swapping the order code on the BOM is straightforward.
