The 690 V rating (52.5 kA) means it can sit on a 690 V line without cascading upstream, which is rare for a 25 A MCCB. ## Trip unit and thermal performance The ETU320 electronic trip unit allows adjustable overload and short-circuit settings — not a fixed thermal element. Minimum trip setting is 38 A, maximum 300 A, so the same breaker frame can be tuned for different load sizes by swapping the trip unit or adjusting the dial. Power loss is a low 0.5 W maximum — negligible for panel thermal calculations.","metaTitle":"Siemens 3VA2025-8HL46-0AA0 SENTRON MCCB, 25 A, 4-Pole, 440 k","metaDescription":"Siemens SENTRON 3VA2025-8HL46-0AA0 molded case circuit breaker, 25 A continuous, 4-pole, ETU320 trip unit, 440 kA at 240 V.
