3VA4145-5ED34-0AA0  -  45Amp Circuit  Breaker

If you’re looking for a dependable 45 amp breaker that just does its job without overcomplication, the Siemens 3VA4145-5ED34-0AA0 is a solid choice. Part of the SENTRON 3VA4 line, this 3-pole molded case circuit breaker is built for everyday protection in commercial and industrial setups where reliability matters more than bells and whistles. It comes equipped with a thermal-magnetic trip unit (TM210) that’s factory set, so there’s nothing to dial in or second-guess. You install it, and it works. With a 35 kA interrupting rating at 480V, it’s capable of handling serious fault conditions while helping protect your equipment from damage and unexpected downtime. This is the kind of breaker you’ll typically see in panel upgrades, new installations, or maintenance replacements—especially when you want something straightforward, durable, and backed by a well-known manufacturer like Siemens.
