Product details

At 415/440 V it still holds 121 kA, dropping to 79 kA at 500 V and 5.1 kA at 690 V, so the SCCR coordination study needs to check the voltage at the fault point, not just the system nominal. The breaker carries a 1 auxiliary switch plus 1 trip alarm switch (HP version) as standard, so you get both a position signal and a separate fault-indication contact without adding a module.

Above that it derates linearly: 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, 213 A at 70 °C. Maximum power loss is 48 W, so ventilation or spacing in the enclosure matters when ganging multiple breakers.

Frequently asked questions

Where can I buy 3VA2225-5HN42-0AG0 and how do I get a price?

This part is sourced and quoted to order against an RFQ through independent distribution channels. Submit an RFQ for current availability and pricing — no stock count or price is published here.

Will 3VA2225-5HN42-0AG0 drop into a panel specified around 3VA2225-5HN42-0BB0 without rewiring?

The 3VA2225-5HN42-0AG0 shares the same 140 mm width, 181 mm height, and 86 mm depth as the 3VA2225-5HN42-0BB0 variant — both are 4-pole SENTRON 3VA2 frames. The difference is the trip unit: the -0AG0 carries an ETU350 electronic trip, while the -0BB0 uses a different release design. Mechanically they interchange, but the protection curve and settings differ, so the coordination study must be rechecked.

What compliance documentation does Siemens provide for 3VA2225-5HN42-0AG0?

As a SENTRON molded case circuit breaker, this part carries the standard Siemens compliance package including IEC 60947-2 certification, UL 489 listing, and CE marking. RoHS and REACH declarations are available through the Siemens Industry Online Support portal.
