Siemens 3VA4110-5ED34-0AA0 Three-Phase Circuit Breaker

Siemens 3VA4110-5ED34-0AA0 is a three-pole molded-case circuit breaker (MCCB) from Siemens’ 3VA protection family, designed to interrupt power safely in three‑phase electrical systems. The unit is rated for 100 A nominal current and up to 600 V AC, making it suitable for protecting feeders and motors in distribution panels, switchgear, and motor control centers within industrial and commercial installations. With its three-pole construction, all three phases are disconnected simultaneously for reliable fault isolation, improving system protection and operator safety. This configuration is commonly used as both main and branch circuit protection in environments where compact form factors and robust short‑circuit protection are required, such as data centers, manufacturing lines, and HVAC instrumentation layouts. The part number 3VA4110-5ED34-0AA0 uniquely identifies this specific Siemens MCCB configuration, ensuring compatibility with Siemens protection schemes and standard enclosure footprints across compatible panel systems.
