It carries a full-scale current setting of 100 A across the full ambient temperature range from 40 °C to 70 °C, with no derating needed up to that ceiling — the thermal curve holds flat at 100 A from 40 °C through 70 °C. That means you can install it in a warm panel or near other heat sources without recalculating the trip point.
Breaking capacity and selectivity headroom
At 240 V it interrupts 187 kA; at 415 V and 440 V it holds 121 kA; at 500 V it still manages 75.6 kA. Only at 690 V does it drop to 3 kA — that is the limit for 690 V line-to-line applications. For a 400 V distribution panel, 121 kA gives generous selectivity headroom against a transformer or a larger upstream MCCB.
Adjustable trip and auxiliary functions
The adjustable overload trip range spans 150 A minimum to 1 200 A maximum, with an initial setting of 20 A. That wide band lets you tune the long-time pickup to the actual load without swapping the breaker body. Two auxiliary switches (HQ design) are fitted for remote status indication. Communication function is included, so the breaker can report its state to a BMS or PLC over the SENTRON communication bus.
The 3VA2010-5JQ32-0DC0 measures 181 mm high, 105 mm wide, and 86 mm deep — a standard 3-pole MCCB footprint that fits most SENTRON distribution panels and retrofit slots. Power loss is 16 W maximum, which is moderate for a 100 A frame; factor it into the enclosure thermal calculation if you are packing multiple breakers in a sealed cabinet.
