Breaking capacity is 330 kA at 240 V AC, dropping to 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3 kA at 690 V. That's unusual; most MCCBs start stepping down above 40 °C. The ETU850 release is adjustable between 38 A and 300 A (the minimum and maximum settings), so this breaker can be dialed to protect a feeder or a downstream panel, not just a fixed load. Power loss is 0.5 W maximum — negligible for thermal budget inside a packed panel. ## Mounting and footprint That's a 4-pole frame in the 3VA2 compact footprint — fits standard panel-mount cutouts for this class. No DIN-rail clip; it bolts to a mounting plate.","metaTitle":"Siemens 3VA2025-7KP46-0AA0 SENTRON MCCB, 25 A, 4-Pole, ETU85","metaDescription":"Siemens SENTRON 3VA2025-7KP46-0AA0 molded case circuit breaker, 25 A continuous, 4-pole, ETU850 release, 330 kA at 240 V.

Pricing and stock are confirmed at quote time; this is a standard catalog item sourced through Siemens distribution, so lead times are typically short for active parts."},{"question":"What is the closest functional second-source to 3VA2025-7KP46-0AA0?","answer":"The 3VA2125-8KQ42-0AA0 is a peer in the same SENTRON 3VA2 family. Both are 4-pole MCCBs with electronic trip units, but the 3VA2125-8KQ42-0AA0 carries a higher continuous current rating (125 A vs 25 A). The footprint (140 mm width) and mounting pattern are shared, so a panel laid out for one accepts the other without rewiring — but the trip unit and breaker frame are sized differently, so verify the load before swapping."},{"question":"What compliance documentation does Siemens provide for this MCCB?","answer":"As a SENTRON product, it carries UL, CSA, IEC, and CE certifications standard for the 3VA2 family.
