3VA4145-6ED34-0AA0 - 45Amp Circuit Breaker

3VA4145-6ED34-0AA0  -  45Amp Circuit Breaker

When you're working with electrical systems, you don’t really get a second chance if something goes wrong. That’s why choosing the right breaker matters. The Siemens 3VA4145-6ED34-0AA0 is designed to handle tough conditions while keeping your equipment protected and your system running the way it should. This 45 amp, 3-pole molded case circuit breaker is part of Siemens’ SENTRON 3VA4 line, known for consistent performance in commercial and industrial setups. It offers a 65kA interrupting capacity at 480V, which means it can safely handle high fault currents without putting the rest of your system at risk. It uses a thermal-magnetic trip unit (TM210), so you’re getting straightforward, dependable protection against both overloads and short circuits. No complicated adjustments—just reliable operation that does its job when it needs to. Another thing people like about this model is its size. It fits into tighter panel spaces without sacrificing performance, which is always a plus when you're working inside crowded enclosures.
