Product description

The Siemens 3RT2036-1SB30 is a 3-pole power contactor designed for AC-3e/AC-3 applications, rated at 51A and 22kW at 400V. It features a 21-33V AC/DC coil and an integrated varistor for surge suppression. This model includes 1 normally closed (NC) auxiliary contact and is specifically designed for PLC (Programmable Logic Controller) outputs, indicated by 'F-PLC-IN'. Screw terminals are used for main connections.

This contactor is optimized for direct interfacing with PLC outputs in industrial automation systems. It is used for switching loads such as motors, heaters, or lighting where a PLC controls the power. The integrated varistor protects the coil from transient voltages.
