Siemens 3VA6115-6JQ31-0AA0 Three Phase Circuit Breaker

Siemens 3VA6115-6JQ31-0AA0 is a UL-listed three-pole molded‑case circuit breaker designed for three‑phase distribution, rated for 150 A and a maximum of 600 V AC. It incorporates Siemens ETU5‑LSIG electronic trip unit, delivering reliable protection with LSIG‑type trip characteristics suitable for coordination within motor feeders and distribution panels. The breaker provides short‑circuit interrupting capacities of 22 kAIC at 600 V and 65 kAIC at 480 V, enabling designers to meet fault-current requirements while preserving selectivity with upstream protection devices. As part of the 3VA61 family, this model is built to protect feeders and equipment in commercial and industrial electrical installations and is commonly used where robust protection and clear fault signaling are essential. It integrates with standard panelboard and switchgear configurations, supporting protection schemes in systems up to 600 V AC across three phases.
