3VA5215-6EF31-0AA0 - HFAS 150 Amp Circuit Breaker

3VA5215-6EF31-0AA0 - HFAS 150 Amp Circuit Breaker

When you're dealing with electrical systems, you don’t get much room for error. The Siemens 3VA5215-6EF31-0AA0 is built for that reality—straightforward, dependable protection for systems that need to stay up and running.This is a 150 amp, 3-pole molded case circuit breaker from Siemens’ 3VA5 line, designed to handle both everyday loads and unexpected faults without overcomplicating things. It uses a thermal magnetic trip unit (TM240), which means it responds to overloads over time and reacts instantly to short circuits. No adjustments needed—it’s set to do its job right out of the box. It’s also sized to fit comfortably in most panels, so you’re not fighting for space during installation.
