3VA5320-5GC41-2AA0 SIEMENS

The 3VA5320-5GC41-2AA0 is a robust and reliable circuit breaker from Siemens' 3VA5 UL series, designed for optimal performance in demanding electrical systems. This 4-pole circuit breaker provides comprehensive line protection, ensuring the safety and integrity of electrical circuits. With a frame size of 400, it offers a breaking capacity class M, capable of interrupting fault currents up to 35kA at 480V. The TM230 trip unit provides fixed thermal-magnetic protection, enhancing the breaker's ability to respond to both overload and short-circuit conditions. Its rated current (In) is 200A, while the fixed short-circuit protection (Ii) is adjustable between 5 to 10 times the rated current. This allows for precise customization of protection settings to match specific application requirements. Notably, this model does not include overload protection, focusing instead on instantaneous short-circuit interruption. It also features neutral protection with 1 unequipped (w/o) connection, simplifying installation and reducing potential wiring errors. The 3VA5320-5GC41-2AA0 is ideal for applications where reliable and fast short-circuit protection is paramount.
