The Siemens SENTRON 3VA2010-6HN32-0AF0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current across the full ambient temperature range from 40 °C to 70 °C — no derating needed up to the 70 °C mark. Breaking capacity is the headline here: 242 kA at 240 VAC, 187 kA at 415/440 V, 121 kA at 500 V, and 3 kA at 690 V.
Depth of 86 mm means it clears most standard enclosure depths (200 mm or deeper) without issue. The auxiliary switch configuration is 1 auxiliary + 1 trip alarm switch HQ, which provides both a status mirror and a separate fault indication contact — useful for remote monitoring or PLC input.
Electrical characteristics and thermal behavior
Maximum power loss is 13.5 W at rated current. The trip indicator is present, so after a fault event you get a visual flag without needing to reset the breaker to check.
