The Siemens SENTRON 3VA2010-5HN32-0AE0 is a 3-pole molded case circuit breaker rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. That 100 A holds steady at every 5 °C step, which simplifies panel calculations when the breaker sits near other heat sources. The interrupting capacity climbs to 187 kA at 240 V, drops to 121 kA at 415 V and 440 V, then to 75.6 kA at 500 V, and 3 kA at 690 V. For a 480 V panel, the 75.6 kA figure gives solid SCCR headroom for most downstream coordination studies. Maximum power loss hits 13.5 W — a useful number when calculating enclosure heat rise, especially in a packed panel.
Auxiliary switch configuration and line protection design
This variant ships with four auxiliary switches (HQ type) integrated. That means status feedback for open/closed and tripped conditions is available without adding external relay blocks — saves DIN rail space and wiring time. That 105 mm width on a 3-pole 100 A frame is standard for panel cutout planning; verify the mounting footprint against your existing backpanel layout.
