Product details

The 3VA2225-5KP42-0AL0: Interrupting capacity runs 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V. Panel builders will find the 86 mm depth leaves clearance in shallow enclosures.

Trip unit and thermal derating

It includes a trip indicator and communication function for status monitoring. Above that, it derates: 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. If your panel runs hot, factor the derate into your load schedule rather than oversizing the frame. Auxiliary switching includes two auxiliary switches, one trip alarm switch, and one electrical alarm switch — enough for remote status and fault annunciation without an add-on module.

Frequently asked questions

What is the interrupting capacity of this MCCB at different voltages?

187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V. That high 187 kA figure at 240 V makes it suitable for high-fault service-entrance applications.

Where can I buy this part and how is it quoted?

Sourced through independent distribution channels. Availability and current pricing are confirmed at quote time against an RFQ — no volume commitment required for a single unit.
