Siemens 3RT2038-3KB40 Power Contactor - 80A, 37kW, 24V DC PLC Output
Siemens 3RT2038-3KB40: 80A, 37kW 3-pole power contactor, 24V DC coil, PLC output compatible.
The Siemens 3RT2038-3KB40 is a 3-pole power contactor rated for AC-3e/AC-3 duty, with a 80A current capacity and a 37 kW power rating at 400V. This S2 frame size contactor is specifically designed for use with PLC outputs, featuring a 24V DC coil with a control voltage range of 0.8 to 1.2 times Uc. It includes an integrated varistor for surge protection and comes with 1 normally open (NO) and 1 normally closed (NC) auxiliary contact. Both the main circuit and control/auxiliary circuits utilize screw terminals.
This contactor is ideal for applications requiring direct switching from programmable logic controller (PLC) outputs. Its suitability for PLC integration, combined with its robust 80A rating, makes it a versatile choice for motor control, power switching, and automation tasks in manufacturing, building automation, and process control systems. The integrated varistor helps protect the PLC output from back-EMF generated by the contactor coil.
