Product details

The Siemens SENTRON 3VA2125-6HL46-0AA0 is a 4-pole molded case circuit breaker rated for 25 A continuous current, with an ETU320 electronic trip unit.

Breaking capacity drops with voltage: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V. For 400/415 V panels, the 187 kA rating covers most industrial service-entrance and sub-distribution applications.

Thermal performance and operating range

Rated continuous current holds at 25 A across the full ambient range from 40 °C to 70 °C — no derating needed up to 70 °C ambient. Operating temperature spans -25 °C to 70 °C, storage from -40 °C to 80 °C. The 0.6 W maximum power loss is negligible for panel thermal budgeting.

Frequently asked questions

Where can I buy 3VA2125-6HL46-0AA0 and 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.

What is the breaking capacity of this MCCB at 240 V?

242 kA at 240 V, which covers very high fault-current installations like transformer secondaries.

Does this breaker require derating at high ambient temperatures?

No derating needed — the 25 A rating holds across the full 40 °C to 70 °C ambient range.
