Siemens 3RT2035-3NP30 S2 Power Contactor 41A, 18.5kW with Varistor & Spring-Loaded Terminal Original Brand New

Overview

The Siemens 3RT2035-3NP30 is a high-performance, S2-sized power contactor designed for reliable and efficient switching of electrical loads up to 41 A. This robust 3-pole contactor is engineered for use in demanding industrial applications, offering exceptional performance for motors up to 18.5 kW at 400 V. Its versatility is further enhanced by a wide control voltage range of 175-280 V AC/DC, making it suitable for a variety of power systems. A key feature is the integrated varistor, which provides superior surge protection for the control coil, extending the product's lifespan and ensuring system stability. The combination of screw terminals for the main circuit and innovative spring-loaded terminals for the control and auxiliary circuits simplifies installation and ensures a vibration-proof connection.
