3VA5140-4EC31-0AA0 SIEMENS

The 3VA5140-4EC31-0AA0 is a robust 3-pole circuit breaker from Siemens, designed for reliable line protection in industrial and commercial applications. It falls under the 3VA5 UL Frame 125 series, indicating its physical size and mounting compatibility. This circuit breaker boasts a breaking capacity class S, capable of interrupting fault currents up to 25 kA at 480 V, ensuring electrical system safety. Equipped with a TM230 trip unit, it provides comprehensive protection against overload and short-circuit conditions. The rated current (In) is 40 A, with overload protection (Ir) fixed at 40 A to prevent damage from sustained overcurrents. Short-circuit protection (Ii) is set at 5 to 10 times the rated current (In), offering instantaneous tripping for high-fault currents. This model is specifically designed for line protection applications, safeguarding electrical circuits and equipment from potential hazards. The FTAM functionality enhances its performance and reliability in demanding environments. Note that this circuit breaker is supplied without connection terminals, allowing for flexible wiring configurations based on specific installation requirements.
