Rated breaking capacity hits 100 kA at 400 V, 480 V, 500 V, and 690 V AC — that's high enough for most industrial distribution panels where the prospective fault current is substantial. Screw terminals for the main circuit accept 2x (0.5 to 1.5 mm²) solid or stranded, or 2x (0.75 to 2.5 mm²).
Integration Notes
Depth is 97 mm, height is 97 mm — the same footprint as the wider SIRIUS 3RV2 family. Side clearance of 30 mm to adjacent devices is recommended. The screw terminals are M3 for the main contacts. No ground-fault detection on this variant — that's a separate function if your application requires it.
Ratings in Context
The auxiliary contact ratings: 1 A at 24 V, 0.5 A at 120/125/230 V, and 0.15 A at 60 V. These are the switching capacities for the auxiliary contact block integrated into the breaker — useful for feeding a status signal back to a PLC or contactor coil. Maximum switching frequency under AC-3 duty (motor starting) is 15 operations per hour. That's typical for a motor protection breaker — it's not designed for high-cycle jogging or rapid reversing.
