It snaps onto DIN rail (REG) and occupies 2 width units (about 36 mm), with N on the left side. ## Ratings that matter for panel fit Terminals accept 1 to 16 mm² solid or stranded copper, torqued to 2.5–3 N·m. The instantaneous design means no intentional delay — it trips within a cycle on a residual fault, which is what you want for shock protection but means nuisance tripping is possible on circuits with high inrush or capacitive leakage. ## Wiring and mounting notes Supply can enter from top or bottom — no orientation restriction. The IP20 rating applies only when the distribution board is installed with conductors connected, so the device itself is not touch-safe until enclosed. Silicon-free construction is confirmed, relevant for potting or conformal-coating environments where silicone outgassing can cause contact issues.","metaTitle":"Siemens 5SM3111-0KL SENTRON RCCB, 2-pole, 16 A, 10 mA, 230 V","metaDescription":"Siemens SENTRON 5SM3111-0KL residual current circuit breaker, 2-pole type AC, 16 A rated, 10 mA trip, 230 V AC, DIN rail mount.
