3VA5215-5ED31-0AA0 - MFAS 150 Amp Circuit Breaker Description
3VA5215-5ED31-0AA0 - MFAS 150 Amp Circuit Breaker
The 3VA5215-5ED31-0AA0 is a 150 amp, three-pole thermal magnetic circuit breaker commonly used in commercial and light industrial power distribution. It’s built on the Siemens 3VA52 UL frame and rated for systems up to 480 volts. With a 35kA interrupting rating, it’s well suited for installations where available fault current isn’t low and dependable interruption is important. This breaker uses a thermal magnetic trip unit with fixed settings. That means there’s nothing to adjust or dial in during installation. Overload protection is set at 150 amps, and the instantaneous short-circuit trip activates at ten times the rated current. In real-world terms, it helps protect wiring and connected equipment without being overly sensitive. The three-pole layout supports standard three-phase loads found in panels, switchgear, and distribution equipment.
