Product details

The Siemens SENTRON 3VA2025-7HM42-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated for line protection at 25 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. The ETU330 electronic trip unit provides adjustable N-conductor protection (OFF or 100 % of phase rating) and ground-fault monitoring via summation current sensing on L + N — a useful feature for detecting leakage in solidly-grounded systems.

Deployment context

The 4-pole configuration with adjustable neutral protection makes it a natural fit for three-phase four-wire systems (e.g., 400/230 V or 480/277 V) where the neutral conductor needs coordinated overcurrent and ground-fault protection.

Frequently asked questions

Where can I buy 3VA2025-7HM42-0AA0?

This part is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.

What is the breaking capacity of 3VA2025-7HM42-0AA0 at 415 V?

The breaking capacity is 242 kA at 415 V, which is the same rating as at 440 V.

Does 3VA2025-7HM42-0AA0 include ground-fault monitoring?

Yes, it includes ground-fault monitoring via summation current formation on the L + N conductor, integrated into the ETU330 trip unit.
