Siemens 3RT2535-1NF30 Power Contactor 35A AC-3, 18.5 kW / 400V, 4-Pole with Integrated Varistor Original Brand New

Overview

The Siemens SIRIUS 3RT2535-1NF30 Power Contactor is a robust and flexible switching solution designed for high-performance industrial applications. As part of the SIRIUS 3RT2 series, this 4-pole contactor is perfectly suited for switching resistive and low-inductance loads (AC-1) as well as motor loads up to 18.5 kW at 400 V (AC-3).

Its most notable feature is the wide operating voltage range coil (83-155 V AC/DC), offering maximum flexibility and simplified inventory management. With an integrated varistor for surge protection, the contactor ensures high reliability and extended coil life by suppressing switching overvoltages. Rated for 35 A and built in the compact Size S2 housing, the 3RT2535-1NF30 utilizes secure and reliable screw terminals for all connections.
