This suits it for circuits with inductive loads like small motors, fluorescent lighting banks, or transformer-fed equipment where a B-curve would nuisance-trip on startup. Rated for single-phase operation up to 250 V AC and multi-phase operation up to 440 V AC at 50/60 Hz, the 5SL4150-7RC covers the common 240/415 V split used in European-style panelboards. The 18 mm width (1 MW) and 76 mm depth fit within the same cutout footprint as any other SENTRON 1-pole MCB. IP20 with connected conductors — suitable for enclosure interiors where live parts are behind a door. The sealable design allows panel builders to lock the toggle position after commissioning.","metaTitle":"Siemens 5SL4150-7RC SENTRON MCB, 1P C 50 A, 10 kA","metaDescription":"Siemens SENTRON 5SL4150-7RC miniature circuit breaker, 1-pole, C-curve, 50 A, 10 kA breaking capacity per EN 60898.
