Product details

This MCCB delivers 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V.

Thermal derating — continuous current vs. ambient

Above that, the TM240 release derates: 243 A at 55 °C, 237 A at 60 °C, 230 A at 65 °C, 223 A at 70 °C.

Dimensions are 105 mm wide, 158 mm high, 70 mm deep. The 3-pole form factor with integrated undervoltage release means one less auxiliary to wire separately — the UVR coil is factory-installed, so verify control voltage matches the panel's trip-coil supply.

Power loss and thermal budget

Maximum power loss is 59.5 W at rated current. That heat stays inside the enclosure — factor it into the panel's thermal calculation, especially if the MCCB is grouped with other high-current devices in a sealed cabinet.

Frequently asked questions

Where can I buy 3VA1225-5EF32-0DA0 and get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What are the key ratings for 3VA1225-5EF32-0DA0?

It is a 3-pole, 250 A (at 40 °C) MCCB with a TM240 thermal-magnetic release, 187 kA breaking capacity at 240 V, and an 800 V rated insulation voltage. It includes a factory-installed undervoltage release.

What is the width and depth of 3VA1225-5EF32-0DA0?

Width is 105 mm, depth is 70 mm, height is 158 mm. It fits a standard MCCB panel footprint.

Will 3VA1225-5EF32-0DA0 drop into a panel specified for 3VA1110-5ED36-0AC0?

No — the 3VA1225-5EF32-0DA0 is a 250 A frame, while the 3VA1110-5ED36-0AC0 is a 100 A frame. They share the SENTRON platform but differ in physical size, bus bar spacing, and lug capacity. Panel cutouts and bus work would need to be re-engineered for the larger frame.
