3VA4111-5ED34-0AA0 - 110Amp Circuit Breaker

Siemens 3VA4111-5ED34-0AA0 Molded Case Circuit Breaker – 110A, 3-Pole, 35kA @ 480V

When you’re working on a panel or upgrading a system, you don’t want to second-guess your protection. The Siemens 3VA4111-5ED34-0AA0 is one of those breakers you install and don’t have to think about again.

This 110 amp, 3-pole molded case circuit breaker is part of Siemens’ 3VA4 line, built for everyday use in commercial and industrial setups. It’s rated for 35 kA at 480V, so it can handle serious fault conditions without hesitation. Whether you’re protecting feeders, equipment, or distribution lines, it’s designed to step in when something goes wrong—and stay out of the way when everything’s running smoothly.

The built-in thermal-magnetic trip unit (TM210) takes care of both overloads and short circuits. Overload protection is fixed at 110A, and the instantaneous trip kicks in at 10 times that rating. No complicated adjustments, no guesswork—just straightforward protection that does what it’s supposed to do.
