This is a current-production part — no end-of-life notice on file. ## Fit and installation Width is 18 mm (1 width unit), depth 76 mm, height 90 mm. Mounts in any position on standard DIN rail. The IP20 rating applies only with conductors connected — treat it as a panel-interior device, not for exposed mounting. Single-pole switching on the phase only — no neutral pole. Rated for single-phase operation up to 250 V AC, multi-phase up to 440 V AC. Sealable enclosure option is available if the application requires tamper-proofing by the utility or facility manager. This is an active, current-production line — no obsolescence notice.","metaTitle":"Siemens 5SL4103-8CC SENTRON MCB, 1P D 3A 10kA","metaDescription":"Siemens SENTRON 5SL4103-8CC miniature circuit breaker, 1-pole, D-curve, 3 A, 10 kA breaking capacity per EN 60898.
