Rated 400 V AC with a C-curve trip characteristic, the 5SY4480-7 delivers 10 kA breaking capacity per EN 60898-1 and 15 kA at DC per IEC 60947-2. The 4-pole design switches all three phases plus the neutral (though neutral is not switched internally — the fourth pole is a switched neutral for isolation). The breaker is sealable, halogen-free, and silicon-free, which simplifies compliance in food-and-bev or clean-room panels where outgassing is restricted. ## Mounting and environmental fit Mounting position is any — vertical, horizontal, or inverted — so it fits tight gland-plate layouts. Ambient temperature range is -40 °C to +75 °C, with derating above 55 °C: max 95 % RH at 55 °C, 55 % at 70 °C, 35 % at 75 °C. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz.","metaTitle":"Siemens 5SY4480-7 SENTRON MCB, 4P C-curve, 10 kA IEC, 15 kA","metaDescription":"Siemens 5SY4480-7 SENTRON 4-pole MCB, C-curve, 10 kA (IEC 60898-1) / 15 kA DC (IEC 60947-2).
