That matters for selectivity coordination downstream — you can shape the trip response to keep a branch fault from taking out the whole feeder. The communication function onboard means this breaker can report status and trip events to a higher-level control system, which is useful for remote monitoring or predictive maintenance on a critical line. Breaking capacity is the headline spec for an MCCB: this one delivers 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V. The 3-pole construction suits three-phase feeders. Front-side IP40 protection means tools or fingers won't contact live parts from the front, but the breaker is not sealed against dust ingress — it belongs inside an enclosure, not in a washdown area.
Panel fit and footprint
If you are replacing an older 3VA1 frame breaker, check the mounting hole pattern; the 3VA2 frame shares the same 105 mm width but verify the depth clearance against your existing backpanel.
