The Siemens SENTRON 3VA2010-5HN32-0KL0 is a 3-pole molded case circuit breaker rated for 100 A continuous current across the full ambient range from 40 °C up to 70 °C — no derating needed in a warm panel. Its interrupting capacity hits 187 kA at 240 V, drops to 121 kA at 415/440 V, 75.6 kA at 500 V, and 3 kA at 690 V, so it handles high-fault industrial feeds without cascading upstream.
At 415 V the 121 kA still covers most industrial main-feeder scenarios. For 690 V applications with fault currents above 3 kA, the 5SQ2370-2YA05 peer carries a different interrupting curve worth checking.
The supplied basic switch order code is 3VA20105HN320AA0; the auxiliary switch block includes two auxiliary switches, one trip alarm switch, and one electrical alarm switch, all factory-installed.
