The Siemens SENTRON 3VA2010-6HN32-0HL0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Breaking capacity hits 242 kA at 240 V, 187 kA at 415/440 V, 121 kA at 500 V, and 3 kA at 690 V, so it handles high-fault utility feeds and transformer-secondaries without cascading upstream.
Auxiliaries and releases
Factory-fitted with a shunt trip (STL) and a full complement of auxiliary switches: two auxiliary switches, one trip-alarm switch, and one electrical alarm switch (HQ configuration). The supplied basic switch is order code 3VA20106HN320AA0.
Environmental and thermal limits
Maximum power loss is 13.5 W — negligible for panel thermal budgeting but worth noting in a sealed enclosure. Trip indicator and voltage trigger are present; no communication function or other measurement function on this base model.
