Above that, the bimetal strip heats up faster and the continuous current must be reduced: 0.95 A at 40 °C, 0.93 A at 45 °C, 0.9 A at 50 °C, 0.88 A at 55 °C, and 0.85 A at 60 °C. The surrounding humidity limits are also temperature-dependent: 95 % RH up to 55 °C, then 55 % RH to 70 °C, then 35 % RH to 75 °C. That matters for condensation in outdoor or washdown cabinets. ## Compliance and approvals Sealable terminals allow the installer to lock the cover after commissioning, which satisfies some site safety audit requirements. Protection class is IP20 with connected conductors, meaning finger-safe but not protected against water ingress.","metaTitle":"Siemens SENTRON 5SY7501-7 MCB, 1 A, C-Curve, 2-Pole 1P+N","metaDescription":"Siemens SENTRON 5SY7501-7 miniature circuit breaker, 1 A rated, C tripping characteristic, 2-pole 1P+N design. 15 kA per EN 60898, 50 kA per IEC 60947-2.
