The 18 mm width (1 modular unit) snaps onto a DIN rail via the quick-assembly system and accepts conductors from 0.75 to 35 mm² solid or stranded at the combined top and bottom terminals. The sealable design allows the panel builder to lock the toggle position after commissioning. The 5SY7103-7CC carries IEC 60947-2 certification for the 30 kA interrupting rating and UL 1077 / CSA C22.2 No. 235 for the 5 kA rating, making it acceptable for panels destined for North American and European installations. It is halogen-free and silicon-free, and the housing provides IP20 touch protection with conductors connected.","metaTitle":"Siemens 5SY7103-7CC SENTRON MCB, 1P, 3 A, C-Curve, 30 kA IEC","metaDescription":"Siemens 5SY7103-7CC SENTRON miniature circuit breaker, 1-pole, 3 A, C characteristic, 30 kA IEC 60947-2, 5 kA UL 1077.
