Siemens 3VA6110-6JQ31-0AA0 Three Phase Circuit Breaker

Siemens 3VA6110-6JQ31-0AA0 is a three-pole molded‑case circuit breaker from the SENTRON 3VA family, mounted in a UL Frame 150 (3VA6) for distribution protection up to 480 V. It is rated In 100 A and delivers 65 kA short‑circuit breaking capacity at 480 V, making it suitable for transformer, generator and plant protection in industrial distributions. The device provides overload protection with Ir adjustable in the 40 A–100 A range and short‑circuit protection in the 0.6–10 × In range, with instantaneous protection Ii in the 1.5–12 × In range; it can be configured with external current transformers for neutral or ground‑fault protection (Ig from 0.2 to 1 × In) and time‑delayed coordination with tg 0.05–0.8 s. This model supports protection options such as ETU560 and LSIG, aligning with UL/IEC 3VA specifications for robust, code‑compliant plant protection. Ideal for three‑phase distribution panels where reliable disconnection is required, it provides a compact, 3‑pole solution for 100 A service feeds, designed for use in transformer and generator protection scenarios as well as main distribution applications in industrial facilities.
