Product details

Its interrupting capacity scales with system voltage: 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V — so at typical 480 V industrial feeds it still holds a very high 75.6 kA, giving plenty of headroom for high-fault panels.

Above that it derates linearly: 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C.

It does not include an undervoltage release or ground-fault monitoring module; the only auxiliary release is the shunt trip. If you need UVR or GF protection, you will add external modules or choose a different variant.

Frequently asked questions

How do I get current pricing and availability for 3VA2225-5HN32-0KA0?

Submit an RFQ through the storefront; the part is sourced to order through independent distribution, and pricing and lead time are confirmed at quote time.

What is the interrupting capacity of this MCCB at 480 V?

At 500 V the interrupting capacity is 75.6 kA; at 440 V it is 121 kA. For a 480 V system the value lies between those two, conservatively 75.6 kA.

What does the shunt trip release on this breaker do?

The shunt trip (STL) allows remote tripping by applying a control voltage to the release coil — used for emergency stops, supervisory shutdowns, or interlocking.
