Product details

Rated 200 A continuous at 40 °C through 50 °C, it derates to 176 A at 70 °C, so the ambient temperature of the enclosure directly governs the usable current — a panel hitting 55 °C drops the rating to 194 A. Breaking capacity is voltage-dependent: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, 17 kA at 500 V, and 11.9 kA at 690 V.

Deployment context and auxiliary options

No undervoltage release and no ground-fault monitoring are included, so if those functions are required they must be added externally or specified on a different variant. Dimensions: 105 mm wide, 158 mm high, 70 mm deep — standard 3-pole MCCB footprint for panel mounting. Maximum power loss is 42 W — factor this into enclosure thermal calculations.

Frequently asked questions

What is the breaking capacity of 3VA1220-4EF32-0KC0 at 415 V?

The breaking capacity is 75.6 kA at 415 V. It also carries 121 kA at 240 V, 52.5 kA at 440 V, 17 kA at 500 V, and 11.9 kA at 690 V.

What does the 200 A rating mean at higher ambient temperatures?

The 200 A rating holds from 40 °C to 50 °C. Above that it derates: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C. Enclosure temperature directly governs usable current.
