3VA5290-5ED31-1AA0 SIEMENS

The 3VA5290-5ED31-1AA0 is a robust 3-pole circuit breaker from Siemens, designed for reliable line protection in various electrical systems. It falls under the 3VA5 UL frame series, offering a frame size of 250. This circuit breaker boasts a breaking capacity class M, capable of interrupting fault currents up to 35kA at 480V, ensuring safety and preventing damage to equipment. Equipped with a TM210 trip unit, it provides comprehensive protection with fixed thermal (FT) and fixed magnetic (FM) settings. The rated current (In) is 90A, with overload protection (Ir) set at 90A, safeguarding against sustained overcurrent conditions. For short-circuit protection, the instantaneous tripping current (Ii) is fixed at 10 times the rated current (10 x In), enabling rapid response to high-level fault currents. This model is UL 489 certified and suitable for SB (naval) applications, demonstrating its compliance with stringent industry standards. It is designed to operate reliably at 50 degrees Celsius without derating. Connection hardware is not included, allowing for flexible installation options based on specific application requirements.
