Siemens 3RT2035-3SP30 Power Contactor 41A, 18.5kW, 3-Pole, AC-3, with Integrated Varistor Original Brand New

Overview

The Siemens 3RT2035-3SP30 Power Contactor from the SIRIUS 3RT2 series is a high-performance, compact switching device engineered for reliable motor and general load control in industrial automation. Classified under performance classes AC-3e/AC-3, this 3-pole contactor is rated for a substantial 41 A and is suitable for motors up to 18.5 kW at 400 V.

A key feature is its broad operating range AC/DC coil (175-280 V), offering flexibility and simplified logistics. It comes equipped with an integrated varistor for superior surge protection, ensuring longevity and reliability of the control circuit. The device features a Size S2 construction, balancing power capacity with a space-saving design. Connection is made robust and maintenance-friendly with screw terminals for the main circuit and spring-loaded terminals (push-in) for the control and auxiliary circuits, enabling quick, vibration-proof wiring. Furthermore, its F-PLC-IN compatibility makes it ideal for safety-related applications requiring direct logic control from a safety PLC.
