Siemens 3RT2017-2KJ82-0LA0 3-Pole Traction Contactor, 12A, 72V DC, 1 NC Aux, SIRIUS Line Original Brand New

Overview

The Siemens 3RT2017-2KJ82-0LA0 is a high-performance 3-pole traction contactor from the trusted SIRIUS line, designed for demanding industrial applications. Engineered for reliability and efficiency, this compact Size S00 contactor handles a rated operational current of 12 A (at 400 V AC) and a rated operational power of 5.5 kW. It is specifically optimized for a 72 V DC control voltage, making it ideal for traction systems and other DC-powered equipment. The integrated suppressor diode provides enhanced protection against voltage peaks, ensuring the longevity of your control circuits. With a single normally closed (1 NC) auxiliary contact and spring-loaded terminals, installation is secure and maintenance is simplified.

Key Features & Benefit

• Exceptional Durability: Built for the rigorous demands of traction applications, ensuring a long service life under challenging conditions.
