3RF2320-2AA04
The Siemens SIRIUS 3RF2320 single-phase solid-state contactor employs zero-crossing switching technology to reduce electrical interference during switching. It has a rated current of 20A (AC-51), a load voltage of 48 to 460V AC, a control voltage of 15 to 24V DC, and spring-clamp terminals for screwless quick installation. It has a response time of only 1 millisecond and an IP20 protection rating.
Product Positioning
The Siemens SIRIUS 3RF2320-2AA04 is a single-phase zero-crossing solid-state contactor with a 20A rated current and spring-clamped terminals, making it suitable for applications requiring screwless quick installation and low electrical interference.
Core Product Advantages and Features
Zero-crossing switching technology
It only conducts when the AC voltage crosses zero, which can significantly reduce the electrical interference to the power grid and surrounding equipment during the switching moment.
Spring clamp terminal
It adopts screwless spring clamp terminals, which allows for quick wiring and maintenance-free operation, making it suitable for control box applications with large-scale installations.
1 millisecond fast response
With a signal response time of only about 1 millisecond, the switching action is rapid and reliable, making it suitable for circuits with high timing requirements.
AC-51 20A rated current
The load voltage ranges from 48 to 460V AC, and the control voltage ranges from 15 to 24V DC, making it widely applicable to load control such as heaters.
