That's a clean linear curve — no sudden drop-off, so you can push ambient to 60 °C and still carry 237 A continuous. The mechanical service life is 15 000 operating cycles typical, which is standard for a frame this size; if the application cycles more than once per shift, budget for a motor drive accessory (the design supports one). ## Auxiliary switching and alarm It ships with one auxiliary switch and one trip alarm switch, both HP (high-performance) contacts — 2 CO contacts total. If you need remote tripping, you'll order a different build state or add an external release later. ## Voltage ratings and environmental limits That covers most 400 V and 480 V distribution systems with headroom. The front face is IP40 — protected against tools and wires over 1 mm, but not sealed against dust ingress.","metaTitle":"Siemens 3VA1225-1AA32-0AG0 SENTRON Switch Disconnector, 250","metaDescription":"Siemens SENTRON 3VA1225-1AA32-0AG0 switch disconnector, 250 A continuous at 40-50 °C, 3-pole MCCB design, busbar connection.
