The coil is 400 V AC, 50 Hz, and the contactor carries 2 NC auxiliary contacts wired via screw terminals. The S2 frame size is a standard Siemens footprint that mates with the usual DIN-rail mount and busbar system in a panel. If you're swapping one into an existing capacitor bank cabinet, the mechanical interlock and auxiliary wiring pattern are the same as other S2 contactors in this family.","metaTitle":"Siemens 3RT2636-1AV05 Capacitor Contactor, AC-6b 50 kVAr, 40","metaDescription":"Siemens 3RT2636-1AV05 capacitor contactor, AC-6b rated 50 kVAr at 400 V, 3-pole, 400 V AC coil, 50 Hz, 2 NC aux contacts, screw terminals, size S2.

The AC-6b duty class accounts for the high inrush current and oscillatory transient that capacitors draw when first energised. A standard motor-rated contactor would see contact welding under that load; this contactor is designed to handle it."},{"question":"What auxiliary contacts does it have?","answer":"It comes with 2 NC (normally closed) auxiliary contacts, terminated with screw terminals.
