Rated at 0.3 A AC, this breaker is sized for very low-current branch circuits — think control transformers, signal lighting, or small resistive loads. The C-curve characteristic (5–10× In) is the default for general-purpose protection; it avoids tripping on the brief inrush of a 50 VA control transformer or a handful of LED drivers. The 2-pole configuration (2P) switches both phase and neutral, with no neutral conductor switching — meaning it disconnects both poles but does not switch the neutral separately. Terminal capacity accepts solid or stranded conductors from 0.75 to 25 mm², with a tightening torque of 2.5 to 3 N·m, covering most panel wiring gauges. Storage range extends to -40 to +75 °C. The breaker is sealable (yes), halogen-free, and silicon-free — important for environments sensitive to outgassing, such as food processing or cleanroom panels. IP20 protection applies with connected conductors, so it is intended for enclosure mounting, not exposed outdoor use. Width is 36 mm (2 width units). The touch-protected terminals (IPXXB) reduce arc-flash risk during live panel work.","metaTitle":"Siemens 5SL4214-7 SENTRON MCB, 2P C 0.3A, 10kA","metaDescription":"Siemens 5SL4214-7 SENTRON miniature circuit breaker, 2-pole, C-curve, 0.3 A, 10 kA breaking capacity per EN 60898.
