It carries no overload or short-circuit protection — this is a pure isolating and switching device for a circuit already protected upstream or by a separate overcurrent relay. The 250 A rating holds flat from 40 °C to 50 °C, then steps down: 243 A at 55 °C, 237 A at 60 °C, 230 A at 65 °C, 223 A at 70 °C. If your panel ambient hits 55 °C, you lose 7 A of headroom — size the upstream protection accordingly. DC rated voltage is 500 V, so it works on 480 V DC bus applications as well. If the control voltage drops, the UVR trips the disconnector open — common for emergency-stop chains or undervoltage lockout schemes. There is no leading contact on the UVR, so the main contacts open without a time delay relative to the auxiliary. Auxiliary contacts are two HQ (high-performance) changeover contacts, wired separately from the main circuit. The device accepts an optional motor drive for remote switching. Front-terminal busbar connection means the main lugs land on the front face — plan your busbar routing to that plane. The busbar connection and front terminal arrangement mean the main conductors land on the front face, so the depth behind the panel face is just the 70 mm body plus clearance for the busbar lugs.","metaTitle":"SENTRON 3VA1225-1AA32-0CC0 Switch Disconnector, 250 A, 3-Pol","metaDescription":"SENTRON 3VA1225-1AA32-0CC0 switch disconnector, 250 A, 3-pole, UVR 120-127 V AC.
