What the ratings mean for fit
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. The ETU350 electronic trip unit gives you adjustable long-time, short-time, instantaneous, and ground-fault protection curves, so you can coordinate selectively with downstream breakers. 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. At 690 V the rating drops to 3 kA, so confirm the available fault current if your system runs at that voltage.
Panel integration and approvals
Dimensions are 181 mm high, 140 mm wide, 86 mm deep — fits standard 4-pole MCCB mounting patterns in switchboards and panelboards. Front protection is IP40, so it is suited for indoor enclosures where tools or fingers might contact the front face but not for washdown areas. 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. Insulation voltage is rated 800 V, covering 480/600 V systems with margin.
