It's built for line protection — meaning it sits at the feeder or main distribution point, not on a motor starter or downstream branch. At 690 V it still clears 17 kA, which matters for 690 V industrial networks common in mining or heavy process plants.
Built-in undervoltage release
This variant ships with an integrated undervoltage release (UVR), designated as design type 3VA9608-0BB24. No auxiliary contact version is fitted, so if you need status feedback to a PLC, you'll add an external auxiliary switch block on the side. The trip indicator is also absent, meaning no local mechanical flag showing tripped vs. off — something to note for troubleshooting panels without HMI.
The 76.2 mm width is three 25.4 mm pole pitches — standard for 3-pole MCCBs in a distribution panel.
