Product details

The Siemens SENTRON 3VA1080-3ED42-0CA0 is a 4-pole molded case circuit breaker (MCCB) rated for 80 A continuous at 40 °C, with a TM210 thermal-magnetic overcurrent release. It ships with the undervoltage release (UVR) already fitted — no separate ordering or field-install step for that coil. The kit is complete: breaker body, UVR, and the line/load terminals. No holes in the box. The 80 A rating holds across the 40–50 °C band; above that it derates to 78 A at 55 °C and 74 A at 70 °C. Breaking capacity is 75.6 kA at 240 V AC, 52.5 kA at 415 V, and 32 kA at 440 V — enough for most industrial service-entrance or feeder positions.

Dimensions: 130 mm tall, 101.6 mm wide, 70 mm deep. The 4-pole width (101.6 mm / 4 in) is standard for a 4-pole MCCB in this class — it drops into the same footprint as other SENTRON 3VA 4-pole frames. Mounting is via screw-mount or DIN rail adapter (check the accessory list for the rail adapter if your panel uses DIN). If you need those extras, look at the 3VA11 or 3VA12 series within the same frame size.

Frequently asked questions

How do I get current pricing and availability for 3VA1080-3ED42-0CA0?

Submit an RFQ against this order code. Availability and current pricing are confirmed at quote time through independent distribution channels.

Will 3VA1080-3ED42-0CA0 drop into a panel specified around 3VA1010-2ED32-0DC0 without rewiring?

Both are 4-pole SENTRON 3VA breakers in the same frame size, so the mounting footprint and pole spacing are identical. The 3VA1080-3ED42-0CA0 carries a higher continuous rating (80 A vs the 3VA1010's lower frame) and includes the undervoltage release. Verify the line/load lug kit matches your bus bars — the lug provision is the same across the 3VA1 frame, but the lug set itself may differ by ampacity.

What compliance documentation does this brand provide for 3VA1080-3ED42-0CA0 (RoHS, REACH, UL, IEC)?

Siemens SENTRON 3VA breakers are designed to IEC 60947-2 and carry CE marking for the European market. UL/CSA listings vary by variant; the specific approvals for this order code should be confirmed from the manufacturer's declaration or the product label. RoHS and REACH compliance declarations are available from Siemens on request.
