It carries two normally-open instantaneous contacts, each rated 10 A at 24 V, with a contact reliability of one incorrect switching operation per 100 million operations at 17 V, 1 mA — suitable for low-energy PLC or safety relay inputs. Front protection is IP20, meaning the terminals are finger-safe inside the enclosure.
The 10 A rating at 24 V is the thermal current (Ith) for the auxiliary contacts — that is the continuous carry current in a resistive circuit. For inductive loads like contactor coils or small solenoids, the switching capacity drops: at 110 V it is rated 1 A, at 230 V it is 6 A, and at 690 V it is 1 A. These are the AC-15 / DC-13 values that govern real-world switching life, not just the thermal rating. It occupies one DIN-rail module space and shares the same mounting hole pattern as the 3RT1 series contactors, so it can be ganged directly alongside them without extra bracketry.
The SIRIUS series is widely stocked across the supply chain, so lead times are typically standard factory-to-distributor cycles.
The substance prohibitance date of 07/01/2006 aligns with RoHS compliance — the part is RoHS-compliant as manufactured after that date. The product extension for auxiliary switches is marked 'Yes', meaning it accepts add-on contact blocks. The shock resistance is rated at 10g / 5 ms and 5g / 10 ms, covering typical vibration in conveyor and pump applications.
