The ETU350 LSI trip unit gives you adjustable short-time pickup (Isd = 1.5–10 × Ir) and a fixed instantaneous pickup (Ii = 12 × In), so you can coordinate downstream breakers and limit arc-flash energy. The neutral conductor protection is adjustable (OFF, 50%, 100%), which is useful when you're feeding a mix of single-phase and three-phase loads and need to avoid nuisance tripping on unbalanced return current. ## Deployment context The 3VA2 frame mounts in standard panel cutouts and accepts plug-in or fixed connections — common in IEC switchgear assemblies, MCCs, and distribution boards. The 4-pole configuration suits three-phase systems with a fully rated neutral, typical in European and Asian 400/415 V networks.","metaTitle":"Siemens 3VA2110-5HN42-0BA0 Circuit Breaker, 55kA @ 415V, 100","metaDescription":"Siemens 3VA2110-5HN42-0BA0 IEC frame 160 circuit breaker, 55kA breaking capacity at 415V, 4-pole, ETU350 LSI, In=100A.
