Siemens 3RT2645-1NF35 SIRIUS Capacitor Contactor - 75kVAr, 83-155V AC/DC
Siemens 3RT2645-1NF35 capacitor contactor with integrated varistor.
The Siemens 3RT2645-1NF35 is a high-capacity capacitor contactor from the SIRIUS 3RT2 series, designed for AC-6b applications up to 75 kVAr at 400V. This 3-pole contactor features a versatile 83-155V AC/DC coil voltage range and an integrated varistor for enhanced surge protection. It comes equipped with two normally closed (2 NC) auxiliary contacts and utilizes screw terminals for secure connection, all within a substantial S3 size frame.
This contactor is engineered to manage the demanding inrush currents associated with switching larger capacitor banks. It incorporates integrated precharging resistors activated by leading auxiliary contacts to limit peak charging current. The built-in varistor offers crucial protection against voltage spikes, ensuring operational stability and prolonging the life of the contactor and connected equipment.
