That C-curve means it handles moderate inrush — think motor starters, pump contactors, or a bank of lighting ballasts — without nuisance tripping on the magnetizing spike, but it still clears a hard fault fast enough to protect the downstream wiring. ## Sizing and fit The 72 V DC maximum rating covers control-circuit applications off a rectified supply.","metaTitle":"Siemens 5SL6240-7RC SENTRON MCB, 40A 2-Pole C-Curve, 7.5 kA","metaDescription":"Siemens SENTRON 5SL6240-7RC miniature circuit breaker, 40 A, 2-pole, C characteristic, 7.5 kA breaking capacity per EN 60898.
