Product details

Current-production 4-pole MCCB with TM210 release

The 3VA1125-3ED42-0AA0: Breaking capacity runs 75.6 kA at 240 V, 52.5 kA at 415 V, and 11.9 kA at 690 V — figures that cover most low-voltage distribution panels in North American and IEC markets. The 4-pole format handles three-phase plus neutral switching, which matters for panels feeding mixed single-phase and three-phase loads or where the neutral must be disconnected for isolation.

DIN-rail footprint and thermal derating

Measures 70 mm deep by 101.6 mm wide by 130 mm high. The 101.6 mm width (4 inches) is the standard 4-pole MCCB footprint. Thermal derating is minimal up to 50 °C (still 25 A), then drops to 24 A at 55 °C and 23 A at 70 °C. Maximum power loss is 8.5 W, which is modest for a 4-pole 25 A frame but still adds to the enclosure's thermal budget. The storage limits govern shipping and warehousing, not running conditions.

Communication function is not built in; no ground-fault monitoring version. An optional motor drive is available as a product extension for remote tripping.

Frequently asked questions

What is the depth of 3VA1125-3ED42-0AA0?

70 mm (2.76 inches). That's the dimension from the mounting surface to the front of the breaker body, not including any handle projection or accessory depth.

Will 3VA1125-3ED42-0AA0 drop into a panel specified around 3VA1020-3ED36-0AA0 without rewiring?

No. The 3VA1125-3ED42-0AA0 is a 4-pole breaker; the 3VA1020-3ED36-0AA0 is 3-pole. The neutral pole requires an additional conductor and a wider DIN-rail footprint. The panel's bus bars and wiring scheme would need modification.
