Combined terminals top and bottom simplify daisy-chaining busbars. Sealable for lockout/tagout compliance. Halogen-free and silicon-free — relevant if the panel sits in a clean room or oxygen-rich environment where silicone outgassing can foul contacts. ## Electrical ratings and derating Rated for AC operation at 50/60 Hz. The DC rating tops out at 72 V — useful for control circuits but not for high-voltage DC bus work. Power loss is 3.2 W per pole at rated current in hot operating state, so a 4-pole unit dissipates about 12.8 W total; factor that into enclosure thermal calculations if the panel is densely packed. Ambient temperature range is -40 to 75 °C, with humidity derating: max 95% RH up to 55 °C, 55% RH up to 70 °C, 35% RH up to 75 °C.","metaTitle":"Siemens 5SY4432-6CC11 SENTRON MCB, 4P, B-Curve, 10 kA","metaDescription":"Siemens 5SY4432-6CC11 SENTRON miniature circuit breaker, 4-pole, B characteristic, 10 kA per EN 60898, rated for railway applications.
