3VA4140-6ED54-0AA0 - 40Amp Circuit Breaker

3VA4140-6ED54-0AA0  -  40 Amp Circuit Breaker

The Siemens 3VA4140-6ED54-0AA0 is a high-performance low voltage molded case circuit breaker (MCCB) designed to deliver dependable circuit protection in commercial and industrial electrical systems. Built on the 3VA41 frame with HEAB (Class H) breaking capacity, this 40 amp circuit breaker provides a powerful 65kA interrupting rating at 277 VAC, helping safeguard equipment from overloads and short circuits. Featuring a thermal-magnetic (TM210) trip unit with fixed long-time (Ir) and instantaneous (Ii) settings, this breaker offers consistent, reliable protection without the need for field adjustments. With its compact 1-pole configuration housed in a 2-pole body and load-side lugs installed, it’s engineered for straightforward integration into existing distribution systems where high interrupting capacity and UL compliance are essential.
