Interrupting capacity is the headline here: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V. This is a line-protection breaker (not motor-protection), so it's sized for feeder and distribution duty — feeding a sub-panel, a busway tap, or a large load bank.
The 86 mm depth, 105 mm width, and 181 mm height match the standard 3VA footprint. If you're replacing an older 3VA or 3VL frame, check the mounting plate and bus bar centers — the 3VA series shares the same bolt-hole pattern as its predecessor, so it usually drops in without re-drilling the back panel.
Integration notes
Communication function is built in — the breaker supports the SENTRON communication platform for power monitoring and remote trip indication. That means you can pull load data and event logs over the plant network without an external CT module or a separate power meter hanging off the bus. Useful for panels feeding branch circuits where ground-fault coordination matters — think datacenter PDU feeds or medical-grade distribution.
