It mounts in any position and accepts solid conductors up to 25 mm². Vibration resistance to 50 m/s² at 25–150 Hz per IEC 60068-2-6 means it holds up on machine-mounted subpanels near rotating equipment. Halogen-free and silicon-free construction. Sealable for lockout/tagout compliance. Touch protection is provided. The operating temperature range is -40 °C to +75 °C, with derating above +55 °C at 95% humidity.","metaTitle":"Siemens 5SN4306-7CN SENTRON MCB, 3P C-Curve 6A 10kA 400V","metaDescription":"Siemens SENTRON 5SN4306-7CN miniature circuit breaker, 3-pole, C-curve, 6A, 10kA breaking capacity at 400V AC.
