What It Is and Where It Goes
The Siemens 5SN1-116 is a DIN rail mount miniature circuit breaker (MCB) from the 5SN1 series, used to protect branch circuits in distribution panels and control cabinets against overloads and short circuits. It snaps onto standard 35 mm DIN rail, so it integrates into the same panel layout as the rest of your Siemens or third-party load center — no special adapter needed.
