3VA5222-7EC61-0AA0 SIEMENS

The 3VA5222-7EC61-0AA0 is a robust and reliable molded case circuit breaker (MCCB) from Siemens' 3VA5 series, designed for UL/CSA standards. This particular model features a frame size of 250A and a breaking capacity class C, capable of interrupting fault currents up to 100kA at 480V AC. It is a 2-pole circuit breaker, making it suitable for single-phase applications or as a main breaker in three-phase systems where only two phases need protection. The breaker is equipped with a TM230 trip unit, specifically configured for line protection. The TM230 trip unit offers fixed thermal overload protection set at the rated current (In) of 225A, ensuring that the circuit is protected against sustained overcurrent conditions. It also incorporates fixed magnetic short-circuit protection with an instantaneous tripping range (Ii) of 5 to 10 times the rated current, providing rapid response to high-level fault currents. This feature helps to minimize damage to equipment and prevent electrical hazards. The absence of a connection indicates that the breaker is designed for direct connection to busbars or other suitable terminals. This circuit breaker is ideal for use in a variety of industrial and commercial applications where reliable and effective circuit protection is essential. Siemens 3VA5 MCCBs are known for their compact design, high performance, and ease of installation.
