It fits a standard DIN rail and screw fixing, occupies 4.5 modular width units, and installs in any orientation. Sealable, halogen-free, silicon-free — suitable for environments where outgassing or contamination must be controlled. Withstands shock at 150 m/s² for 11 ms half-sine and vibration at 50 m/s² from 25 to 150 Hz, per IEC 60068-2-27 and IEC 60068-2-6.","metaTitle":"Siemens 5SP4380-8 SENTRON MCB, 3P D 80A 10kA","metaDescription":"Siemens 5SP4380-8 SENTRON miniature circuit breaker, 3-pole, D-curve, 80 A, 10 kA per EN 60898.
