3VA4111-4ED54-0AA0 - 110 Amp Circuit Breaker

3VA4111-4ED54-0AA0  -  110 Amp Circuit Breaker

Protecting your electrical systems shouldn’t be a gamble. The Siemens 3VA4111-4ED54-0AA0 offers dependable, high-performance circuit protection, specifically designed for demanding industrial and commercial environments. Built on the trusted 3VA41 molded-case platform with Class S (SEAB) interrupt rating, this breaker delivers up to 25 kA at 277 VAC—giving your circuits a strong defense against overloads and faults. Its TM210 thermal-magnetic trip unit comes with fixed Ir and Ii settings (Ir = 110 A, Ii = 10 × In), so you get consistent protection without the need for field adjustments. Because lugs are factory-installed on the load side only, installation is faster and cleaner.

This circuit breaker is ideal when you want a high-performing, easy-to-use protective device with minimal fuss. Its weight and dimensions make it compact — approximately 5.09 in (129.4 mm) tall, 2 in (50.8 mm) wide, and 2.96 in (75.1 mm) deep — so it fits nicely into tight panel layouts.
