This dual-standard certification (IEC 60898-1 for residential/commercial, IEC 60947-2 for industrial, plus UL/CSA for North American acceptance) means the same part can be specified across global BOMs without requalification. ## Panel integration and environmental limits Mounts in any position via the quick-assembly system (DIN rail). The 18 mm width (1 modular unit) and 70 mm installation depth allow dense packing in standard enclosures. Halogen-free and silicon-free construction suits clean-room or sensitive electronics environments.","metaTitle":"Siemens 5SY4118-7 SENTRON MCB, 1P C-curve, 10 kA EN 60898","metaDescription":"Siemens 5SY4118-7 SENTRON miniature circuit breaker, 1-pole C-curve, 10 kA (EN 60898) / 20 kA (IEC 60947-2).
