Siemens 3RT2017-1SB42 SIRIUS Power Contactor, 3-Pole, 12A, 5.5 kW, 24V DC, Suppressor Diode, 1 NC Auxiliary Contact Original Brand New

Overview

The Siemens 3RT2017-1SB42 is a high-performance SIRIUS 3RT2 series power contactor designed for reliable and efficient switching of motors and resistive loads. This compact and robust 3-pole contactor is rated for an operational current of up to 12A and a power output of 5.5 kW at 400V (AC-3e/AC-3).

It features a wide voltage range 24 V DC control supply (0.85-1.85* Uc) with an integrated suppressor diode, which provides superior protection against voltage spikes and extends the contactor’s service life. The unit comes with one normally closed (1 NC) auxiliary contact, offering flexible integration into control circuits. Its screw terminals ensure a secure and easy connection, and the compact frame size S00 makes it ideal for space-constrained applications.

Benefit
