Product details

Breaking capacity is the headline here: 75.6 kA at 240 VAC, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. Power loss at rated load is 10.8 W — negligible for panel thermal budgeting but worth noting if you're packing breakers tight in a sealed enclosure.

At 55 °C it drops to 39 A, at 65 °C to 38 A, and at 70 °C to 37 A.

Panel fit and auxiliary switch configuration

Comes with three auxiliary switches (HQ type) pre-installed — no separate order for status feedback. If you need shunt trip or remote signaling, you're looking at a different suffix in the 3VA1 family.

Frequently asked questions

Does this breaker include auxiliary contacts or a shunt trip?

It includes three pre-installed HQ-type auxiliary switches. No undervoltage release, no ground-fault monitoring, and no communication module on this variant.
