Combined terminals at both top and bottom allow daisy-chaining or feed-through wiring without separate busbar connectors. The breaker is sealable for anti-tamper applications, and touch protection is built in — no exposed live parts when conductors are properly terminated. Ambient temperature range is -40 to +70 °C, storage -40 to +75 °C, with humidity derating: max 95% at 55 °C, 55% at 70 °C, 35% at 75 °C. ## Material and compliance profile Halogen-free and silicon-free construction reduces corrosive off-gassing in enclosed panels — relevant for food-and-bev or marine environments where outgassing can damage contacts. The breaker is classified as energy limiting class 3, meaning it limits let-through energy in a fault, reducing stress on downstream components. No neutral conductor switching — this is a line-only 1P device.","metaTitle":"Siemens 5SY4108-7CC11 SENTRON MCB, 1P C-curve 8A 10kA","metaDescription":"Siemens 5SY4108-7CC11 SENTRON miniature circuit breaker, 1-pole C-curve 8A, 10kA breaking capacity per EN 60898, 400V AC.
