Auxiliaries, Release, and Communication
The breaker ships with a factory-fitted auxiliary switch block — 2 auxiliary switches plus 1 trip alarm switch (HQ type) — and an undervoltage release (UVR). The UVR trips the breaker when control voltage drops below a threshold, which is standard for emergency-stop circuits or undervoltage protection on critical feeders. The communication function (is present, though the protocol isn't specified in this data) means it can integrate with a BMS or SCADA system for remote monitoring and trip indication. The trip indicator is present, so after a fault you get a visual flag — no guesswork on whether it tripped or someone switched it off. No ground-fault monitoring version is included on this order code; if you need GF protection, you'd look at a different suffix in the 3VA family.
Physical Fit and Panel Integration
Dimensions are 248 mm high, 138 mm wide, 110 mm deep — a standard 3-pole MCCB footprint for this current class. It mounts on a DIN rail or can be screw-fixed to a backplate; the 110 mm depth leaves room for rear-connected busbars or cable exits in a typical 600 mm deep enclosure. The width of 138 mm means it takes up roughly 5.4 inches of rail space — factor that into your panel layout if you're packing multiple breakers side by side. Power loss at full rated current is 164.5 W maximum. That's heat that has to be dissipated inside the enclosure — if you're grouping several of these in a sealed cabinet, you'll want to account for the thermal load in your cooling calculation.
