3VA5240-7ED31-0AA0 SIEMENS

The 3VA5240-7ED31-0AA0 is a robust 3-pole circuit breaker from Siemens, designed for reliable line protection in industrial and commercial applications. As part of the 3VA5 UL Frame 250 series, this circuit breaker offers a breaking capacity class C, capable of interrupting fault currents up to 100kA at 480V. It features a TM210 trip unit with fixed thermal-magnetic (FTFM) settings, providing dependable overload and short-circuit protection. The overload protection is set at a fixed current of 40A (Ir=40A), ensuring the circuit breaker trips when the load exceeds this value for a sustained period. For short-circuit protection, the instantaneous trip is set at 10 times the rated current (Ii=10 x In), offering rapid response to high-fault currents. This model is specifically designed for systems requiring a 40A rated current. The 3VA5240-7ED31-0AA0 does not include a connection, allowing for flexible wiring configurations based on the specific installation requirements. Its UL certification ensures compliance with North American safety standards. This circuit breaker provides a reliable and efficient solution for protecting electrical circuits against overloads and short circuits.
