The 3RH2131-2AP60: That 690 V rating matters for 690 V line-to-line panels common in heavy industrial sites; the contactor handles the aux circuit without a separate interposing relay. Three normally-open instantaneous contacts, arcing time 10–15 ms, with a mechanical life of 30 million operations typical — this is the part that outlasts the machine it's in.

Frequently asked questions
How can I order the 3RH2131-2AP60 or check availability?
This is an active-production SIRIUS auxiliary contactor. Submit an RFQ with your target quantity and delivery window; we source it through authorized distribution and confirm lead time and pricing at quote time.
What is the 3RH2131-2AP60 used for?
It's an auxiliary contactor — typically wired to a power contactor's coil circuit to provide feedback contacts (e.g., status to a PLC input) or to interlock multiple contactors in a reversing or star-delta starter. The three NO contacts handle signal-level switching across the full voltage range.
