Breaking capacity is substantial: 100 kA at 240 V and 400 V AC, 42 kA at 500 V, and 6 kA at 690 V.
Key features for the panel builder
Solid wire capacity: 2×(0.5…1.5 mm²) and 2×(0.75…2.5 mm²). Stranded: 2×(1…2.5 mm²) and 2×(2.5…6 mm²). AWG equivalent for main contacts: 2×(14…10). Zero clearance required at the back or sides — 0 mm spacing — so it packs tight against adjacent devices. IP20 protection on the front — finger-safe when installed in an enclosure, but not washdown-rated.
It includes phase failure detection (trips on loss of one phase) but no ground fault detection. The auxiliary switch is a transverse design and the product extension for an auxiliary switch is available — the kit includes the provision, but the switch itself is ordered separately. RoHS compliance date is 01.05.2012 — the substance prohibition date marks the transition to RoHS-compliant production. No UL or CSA listing is explicitly stated in the spec record, but the SIRIUS family typically carries IEC certification for global panel builds.
