Three-pole design, so it switches all phases together. Breaking capacity is 75.6 kA at 240 V, dropping to 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 500/690 V — the SCCR you need for your fault study is the voltage-specific number, not the headline. Maximum power loss is 13.1 W.
No communication function onboard — this is a plain breaker, not a metering or comms variant. If you need remote trip indication, the HQ contact handles that; for energy data you'd step up to the 3VA1 metering version. Trip indicator is present, so after a fault you can visually confirm the breaker tripped rather than someone switched it off. Ground-fault monitoring is not included — specify the GF version separately if you need that.
Physical fit
That 70 mm depth (2.76 in) is the body only — add clearance for the handle throw and wiring bend radius.
