The 50 A rating holds at 35 °C. Above that, the thermal-magnetic trip element derates: 46.35 A at 45 °C, 45.1 A at 50 °C, 43.75 A at 55 °C, and 42.4 A at 60 °C. If the panel ambient runs at 50 °C, size the load at 45 A, not 50. Sealable for lockout/tagout. Halogen-free and silicon-free, which matters in clean-room or sensitive electronics environments.","metaTitle":"Siemens 5SY7250-6 SENTRON MCB, 2-Pole B-Curve 50 A, 15 kA","metaDescription":"Siemens 5SY7250-6 SENTRON miniature circuit breaker, 2-pole, B-curve, 50 A rated at 35 °C, 400 V AC, 15 kA (EN 60898) / 20 kA (IEC 60947-2).
