Product details

Its interrupting capacity reaches 187 kA at 240 V, 121 kA at 415 V, and 121 kA at 440 V — meaning it can safely clear high-fault currents in low-voltage mains without upstream cascading. At 690 V the rating drops to 4.5 kA, so this breaker is best suited for 400 V-class systems where the full 121 kA is available. Thermal derating starts at 55 °C: 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C.

Integration notes

No auxiliary switch or undervoltage release is fitted on this variant.

Frequently asked questions

Where can I buy 3VA2225-5KP32-0KA0 and how do I get a price?

This part is sourced to order through independent distribution. Submit an RFQ for current pricing and availability — figures are confirmed at quote time.

What is the interrupting capacity of 3VA2225-5KP32-0KA0 at 415 V?

121 kA at 415 V, matching the rating at 440 V. At 500 V it drops to 75.6 kA, and at 690 V to 4.5 kA.

Does this MCCB include a shunt trip?

Yes, it is fitted with a shunt trip release (STL) for remote tripping. No undervoltage release or auxiliary switch is included on this variant.
