The Siemens SENTRON 3VA2010-7HN46-0AA0 is a 4-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 flat thermal curve simplifies panel design in warm environments like motor control centers or enclosed switchboards. Breaking capacity hits 330 kA at 240 V and 242 kA at 415 V and 440 V, meaning it can interrupt very high fault currents without upstream fuses or a larger frame — useful for high-capacity transformer secondaries or large motor feeds.
The breaker carries no undervoltage release, no shunt trip, and no communication module as shipped; those are add-on accessories if your application requires remote tripping or monitoring.
