The C-curve (5–10× In magnetic trip) handles moderate inrush from small transformers or lighting ballasts without nuisance tripping, while the 0.5 A rating targets protection of control transformers, signal circuits, or very low-current loads where a standard 6 A or 10 A MCB would not provide adequate overcurrent discrimination. ## Installation & Integration Snap-on mounting to DIN rail. 18 mm width (1 MW) fits standard single-module MCB slots. Sealable design allows lockout/tagout. Supplementary devices can be added via the accessory interface. The 50/60 Hz supply frequency range and 250 V single-phase / 440 V multi-phase ratings match standard European LV networks.","metaTitle":"Siemens 5SL4105-7RC SENTRON MCB, 1P C-curve 0.5A 10kA","metaDescription":"Siemens SENTRON 5SL4105-7RC miniature circuit breaker, 1-pole, C-curve, 0.5 A, 10 kA breaking capacity per EN 60898.
