SIRIUS 3RV1011-1CA15-0BA0 — motor-protective circuit breaker, 2.5 A, Class 10
Rated short-circuit breaking capacity hits 100 kA at 240 V and 400 V AC, then derates to 10 kA at 500 V and 2 kA at 690 V — the 100 kA figure covers the common 400 V distribution level, so it coordinates with most panelboard bus bracing without an upstream current-limiting fuse. Phase failure detection trips the breaker if one phase drops out. No ground-fault detection on this variant.
Screw-type terminals on both main and auxiliary circuits; the main circuit accepts 2x (0.5…1.5 mm²) solid or 2x (0.75…2.5 mm²) stranded per pole. Zero clearance required at the sides and rear — you can butt adjacent devices directly. Shock rated at 25g / 11 ms. Mount in any orientation.
Auxiliary switch and control circuit
This variant includes a factory-fitted auxiliary switch, transverse design, with switching capacity rated at 1 A at 24 V, 0.5 A at 230 V, and 0.15 A at 60 V — enough to signal a PLC input or drop out a holding contactor. Rated insulation voltage 20…690 V, covering low-voltage control circuits up to 690 V line-to-line.
