3VA5135-4EC31-0AA0 SIEMENS

The 3VA5135-4EC31-0AA0 is a UL-listed molded case circuit breaker from Siemens, designed for reliable circuit protection in various applications. This 3-pole circuit breaker falls under the 3VA5 family, known for its compact design and robust performance. It has a frame size of 125A and a breaking capacity class S, capable of interrupting fault currents up to 25kA at 480V. Specifically configured for line protection, the TM230 trip unit provides thermal-magnetic overload and short-circuit protection. The rated current (In) is 35A, with a fixed overload protection setting (Ir) also at 35A. The short-circuit protection (Ii) is fixed at 5 to 10 times the rated current, offering instantaneous tripping for high-level faults. This breaker does not include a connection and requires separate terminals for installation. It is suitable for use in industrial and commercial settings where reliable overcurrent protection is essential. The 3VA5135-4EC31-0AA0 ensures the safety and longevity of electrical systems by quickly disconnecting the circuit in the event of an overload or short circuit.
