AC-6b rated for capacitor switching Integrated precharging resistors Integrated varistor for surge protection Wide AC/DC coil voltage range 2 NC auxiliary contacts Robust S2 size

Product description

The Siemens 3RT2636-1NF35 is a specialized capacitor contactor from the SIRIUS 3RT2 series, designed for AC-6b applications up to 50 kVAr at 400V. This 3-pole contactor features a wide 83-155V AC/DC coil voltage range and includes an integrated varistor for overvoltage protection. It is equipped with two normally closed (2 NC) auxiliary contacts and uses screw terminals for connection, all within an S2 size frame.

This contactor is engineered to manage the high inrush currents typical of switching capacitor banks. Its design includes integrated precharging resistors, activated by leading auxiliary contacts, to limit peak charging current. The integrated varistor adds protection against voltage spikes, ensuring reliable operation and extending the life of connected components.
