Siemens 3RT2046-1XB40-0LA2 SIRIUS Power Contactor, 95A, 45kW, 24V DC, S3 Frame Original Brand New

Overview

The Siemens 3RT2046-1XB40-0LA2 is a high-performance SIRIUS power contactor, specifically designed for traction applications. This robust 3-pole contactor is engineered to handle heavy-duty loads with a rated operational current of 95 A for AC-3e/AC-3 applications and is capable of controlling motors up to 45 kW at 400 V. The compact S3 frame size makes it ideal for space-constrained installations.

Its solid-state operating mechanism, powered by 24 V DC, ensures reliable and precise switching. An integrated varistor provides superior surge protection, safeguarding the control circuit from voltage spikes. The contactor also features one normally open (NO) and one normally closed (NC) auxiliary contact, offering flexible integration into control circuits. With its durable screw terminals, installation is secure and straightforward.

Key Benefit
