Overload protection is fixed at 40 A (Ir = 40 A), and short-circuit protection trips at 10 × In (Ii = 10 × In). ## Integration Notes Mounts in a standard DIN-rail enclosure or direct panel mount via the frame lugs. The 4-pole configuration covers three-phase plus neutral; note the N conductor is unprotected (solid neutral), so the breaker does not provide neutral overload or short-circuit protection — the neutral bar is a pass-through.","metaTitle":"Siemens 3VA1140-3ED42-0AA0-ZD00 Circuit Breaker, 40A, 25kA @","metaDescription":"Siemens 3VA1140-3ED42-0AA0-ZD00 IEC frame 160 circuit breaker, 4-pole, 40A overload protection, 25kA breaking capacity @ 415V.
