The overload protection adjusts Ir from 28A to 40A, and the short-circuit pickup Ii is set 5 to 10 times In, so you can dial it to the branch circuit's inrush without nuisance trips. The nut keeper kit (included) holds the terminal nuts captive during wiring — a small thing that saves time when you're landing lugs in a tight enclosure. The undervoltage release (UVR) runs on 24V DC; if that control voltage drops, the breaker trips, which is standard for emergency-stop or safety-shutdown circuits. Two HQ auxiliary switches plus one HQ trip alarm switch give you status feedback for a PLC or indicator lamp without extra add-on modules.","metaTitle":"3VA1140-3EF32-0BH0 Siemens 3VA1 Circuit Breaker, 40A, 25kA","metaDescription":"Siemens 3VA1140-3EF32-0BH0 IEC frame 160 circuit breaker, 40A, 25kA @ 415V, TM240 overload, UVR 24V DC, 2 aux switches.
