Rated In is 100 A, with overload Ir adjustable from 40 A to 100 A and short-time pickup Isd from 1.5 to 10 × Ir. For most industrial panel applications, that's enough to coordinate with a downstream transformer or a 400 V motor control center without cascading. The ETU350's LSI curve lets you set short-time delay (Isd) to ride through motor inrush or downstream breaker coordination, then clear hard faults fast. The adjustable neutral is a nice touch for 3-phase + N panels where you need to protect the neutral conductor at a lower rating than the phase conductors — common in harmonic-rich loads like VFD banks or UPS inputs. The shunt trip wiring lands on the left-side terminals; keep the control circuit separate from the power conductors to avoid induced pickup on the trip signal. The auxiliary switch and trip alarm switch are pre-wired to a common terminal block on the front face, so you can land your PLC inputs without opening the breaker cover.","metaTitle":"Siemens 3VA2110-5HN42-0KH0 Circuit Breaker, 55kA @ 415V, 100","metaDescription":"Siemens 3VA2110-5HN42-0KH0 IEC frame 160 breaker, 55kA breaking capacity at 415V, ETU350 LSI protection, 100A rated.
