The Siemens 5SJ3116-7RC is a 1-pole miniature circuit breaker from the Retail line, rated 16 A with a C trip characteristic and a 4.5 kA breaking capacity.
Snap-on DIN rail mounting fits standard 35 mm rail in distribution boards and sub-distribution panels.
For installations with higher prospective short-circuit current, a breaker with a higher SCCR would be required.
