The overload protection (Ir) is adjustable from 28 A to 40 A via the TM240 thermal-magnetic trip unit, and the short-circuit protection (Ii) is fixed at 5 to 10 times In (200–400 A). This adjustability lets the site electrical engineer dial in the exact protection curve for the downstream load — a motor branch or a feeder — without swapping trip units. ## Deployment context The 3VA1 frame accepts a range of accessories — auxiliary contacts, shunt trips, undervoltage releases — that snap onto the left or right side without additional wiring space.","metaTitle":"Siemens 3VA1140-3EF32-0AA0-ZD00 Circuit Breaker, 40A, 25kA @","metaDescription":"Siemens 3VA1140-3EF32-0AA0-ZD00 IEC frame 160, 3-pole, 40A, 25kA breaking capacity @ 415V.
