Combined terminals top and bottom simplify daisy-chaining busbars in a distribution board. ## Environmental and compliance profile Halogen-free and silicon-free construction suits clean-room or sensitive electronic environments. The 10 000 mechanical switching cycles are typical for this class — adequate for a protection device that operates rarely, not a daily-switched contactor.","metaTitle":"Siemens 5SY8225-8BB08 SENTRON MCB, 2P 25A D-Curve, 30kA IEC","metaDescription":"Siemens SENTRON 5SY8225-8BB08 miniature circuit breaker, 2-pole, 25 A, D tripping characteristic, 30 kA at 400 V AC per IEC 60947-2.
