Siemens 3VA4140-6ED34-0AA0 Three-Phase AC Contactor

The Siemens 3VA4140-6ED34-0AA0 is a three‑pole molded‑case circuit breaker (MCCB) in the 3VA4140 frame, designed to protect industrial power circuits from overloads and short circuits. It is rated for 40 A (In) and up to 600 V AC, with UL 489 listing and an interrupting capacity reported at 65 kA at 480 V and 25 kA at 600 V depending on the supply conditions. The device measures about 129.4 mm in height, 76.2 mm in width, and 75.1 mm in depth, offers IP40 front protection, and operates from -25 °C to 70 °C ambient conditions. The main current path accepts round conductors on the load side and low‑tab inputs on the infeed side, compatible with 14 AWG to 8 AWG conductors. This 3P MCCB provides reliable overload protection up to 40 A and rapid interruption per UL 489 requirements, making it suitable for installation in industrial control panels and distribution enclosures where compact, compliant protection is required.
