Product details

What this MCCB carries in the nacelle

The interrupting capacity tells the real story: 75.6 kA at 240 V, 52.5 kA at 415 V, and still 7.5 kA at 690 V — numbers that matter when you're coordinating downstream feeders in a turbine's low-voltage switchgear or an industrial MCC lineup.

The 25 A rating holds flat from 40 °C to 50 °C, then derates gently to 23 A at 70 °C — no surprise derating curve for a panel that runs warm. Power loss maxes at 8.5 W; four poles dissipating that in a sealed enclosure needs a thermal check, but in a ventilated panel it's fine.

Dimensions are 130 mm high, 101.6 mm wide, 70 mm deep — a 4-pole frame that fits standard Siemens 3VA mounting footprints.

Frequently asked questions

Where can I buy 3VA1025-3ED42-0AA0 and get a price?

Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time.

Will 3VA1025-3ED42-0AA0 drop into a panel built for a 3VA1110-5ED36-0AC0?

Both are 4-pole 3VA frame MCCBs with the same 130 mm height and 70 mm depth, but the 3VA1110-5ED36-0AC0 is a 100 A frame with different lug sizes and busbar spacing — the 25 A 3VA1025 will physically mount in the same footprint, but the bus connections and cable terminations may not match without re-termination. Verify the line and load conductor sizes before assuming a straight swap.

What compliance documentation does Siemens provide for this MCCB?

As a SENTRON 3VA series product, it carries UL, CSA, and IEC certifications standard to the platform. RoHS and REACH declarations are available through Siemens Industry Online Support. Specific cert numbers for this order code are confirmed at quote time.
