SIEMENS 3RT5054-1AB36 - Power Contactor, 3-pole
The SIEMENS SIRIUS 3RT5054-1AB36 is a 3-pole power contactor engineered for reliable switching of three-phase AC loads up to 30 kW at 400V (AC-3) with a rated operational current of 65 A. This electromechanical control device is actuated by a 110 V AC (50 Hz) / 120 V AC (60 Hz) coil, providing robust performance for motor control applications in industrial machinery, HVAC systems, and pump control. It integrates 1 normally open (NO) and 1 normally closed (NC) auxiliary contacts for enhanced control circuit functionality.
