The Siemens SENTRON 3VA2110-8HL36-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated 100 A continuous at ambient temperatures from 40 °C through 70 °C — no derating needed across that span, which simplifies panel thermal budgeting. The interrupting ratings climb to 440 kA at 240 V and hold at 330 kA through 415–440 V, then step down to 220 kA at 500 V and 52.5 kA at 690 V — giving the panel designer clear SCCR headroom across common industrial voltage levels. Maximum power dissipation is 7.7 W, which keeps heat rise manageable inside a closed enclosure even when the breaker is fully loaded.
Front-face protection is IP40, adequate for clean indoor panel environments where tools or fingers won't contact live parts through the cover. The breaker accepts optional motor drive (: Yes), enabling remote open/close for automated load shedding or emergency stop circuits.
