3VA5340-5EC31-1AA0 SIEMENS

The 3VA5340-5EC31-1AA0 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 breaking capacity class M, rated at 35kA at 480V, ensuring effective short-circuit interruption. This circuit breaker is equipped with a TM230 trip unit, featuring FTAM functionality for enhanced monitoring and control. The In=400A indicates a rated current of 400 Amperes, suitable for demanding applications. Notably, this model does not include overload protection, prioritizing immediate response to short-circuit events. The fixed short circuit protection Ii is set at 5 to 10 times the rated current (In), providing a defined threshold for instantaneous tripping. Compliant with UL489 standards and specifically designated as SB (NAVAL), this breaker meets stringent requirements for naval applications. It is designed to operate reliably in ambient temperatures up to 50 degrees Celsius. This particular configuration is supplied without connection terminals, allowing for flexible integration with diverse connection systems.
