PRODUCT DESCRIPTION
SIEMENS 3RF2420-2AC45 - Solid-State Contactor
This SIEMENS SIRIUS 3RF2 solid-state contactor, part number 3RF2420-2AC45, is engineered for wear-free switching of 3-phase resistive loads (AC-51) up to 20A per phase. Utilizing semiconductor technology with zero-point switching, it provides precise and silent control for applications requiring high switching frequencies, such as industrial heating, lighting, and temperature regulation systems. The device offers extended operational life and reduced maintenance compared to electromechanical contactors.
