Siemens 3RT2017-1UB41-1AA0 Power Contactor 12A, 5.5kW, 3-Pole, 24V DC Original Brand New

Overview

The Siemens 3RT2017-1UB41-1AA0 is a robust and reliable power contactor designed for industrial and commercial electrical systems. Engineered for AC-3e/AC-3 applications, it delivers efficient switching for motors, lighting circuits, and other electrical loads up to 12 A and 5.5 kW at 400 V. With its 3-pole design and 24 V DC coil, it ensures precise control and high operational reliability. The built-in varistor protects the contactor against voltage spikes, while the 1 NO auxiliary contact allows for easy integration with control circuits.

Benefit
