The Siemens SENTRON 3VA2025-8HN46-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated for 25 A continuous current at 40 °C through 70 °C ambient — no derating needed across that span. Breaking capacity is 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V — figures that put it in the high-interrupting category for industrial mains distribution.
The 4-pole footprint matches standard MCCB mounting in SENTRON distribution boards and third-party enclosures.
Continuous current is 25 A across the full -25 °C to 70 °C operating range. Breaking capacity reaches 440 kA at 240 V and 330 kA at 415 V. The trip unit is an ETU350 electronic type. Rated insulation voltage is 800 V.

Both share the same 4-pole SENTRON 3VA frame dimensions (86 mm deep, 140 mm wide, 181 mm high), so the physical footprint is identical. The difference is the trip unit — the -46 suffix carries the ETU350 electronic trip, while the -42 suffix uses a different trip variant. Panel cutouts and bus connections are the same; verify the trip coordination study before swapping.
