Compared to the C-curve 5SL6220-7 (same 2-pole, 2 MW, but 6 kA breaking capacity), the 5SL4202-8 offers the higher 10 kA rating and the D-curve — the choice hinges on whether your downstream load is resistive (C) or inductive/motor (D), and whether your available fault current exceeds 6 kA. ## Integration and mounting — DIN-rail fit, sealable, supplementary devices Sealable design (padlockable toggle) for lockout/tagout compliance; halogen-free and silicon-free construction for environments sensitive to outgassing (clean rooms, food processing).","metaTitle":"Siemens 5SL4202-8 SENTRON MCB, 2P D-curve 2A 10kA","metaDescription":"Siemens 5SL4202-8 SENTRON miniature circuit breaker, 2-pole, D-curve, 2A, 10kA breaking capacity at 400V AC.
