Long-time pickup (Ir) is adjustable from 40A to 100A — that's the continuous current rating you set for the connected load. Short-time pickup (Isd) adjusts from 1.5 to 10 times Ir, with a time delay that allows coordination with downstream breakers. Instantaneous (Ii) is fixed at 12 x In, covering bolted faults. Neutral conductor protection is adjustable: OFF, 50%, or 100% of phase current. That's useful on 4-wire systems where you need to protect the neutral against harmonics or unbalanced loads. ## Integrated aux and alarm contacts That means you get a status contact for remote indication of the breaker position (open/closed) and a separate contact that signals when the breaker has tripped on a fault. No need to order add-on blocks for basic remote monitoring — it's already on the van. The 4-pole footprint takes up four module widths on the rail. Terminal capacity accepts cable sizes typical for 100A circuits — plan for lug or busbar connections per the manufacturer's torque specs. The nut keeper kit (included) helps retain the terminal screws during wiring, which saves time on the panel assembly line.","metaTitle":"Siemens 3VA2010-6HN42-0AF0 Circuit Breaker, 100A, 85kA @ 415","metaDescription":"Siemens 3VA2010-6HN42-0AF0 IEC frame 100 circuit breaker, 85kA breaking capacity at 415V, ETU350 LSI protection, 100A rated.
