Frequently asked questions

What is zero-point switching in the Siemens 3RF2190-1AA06 relay?

Zero-point switching means the relay activates and deactivates the load precisely when the AC voltage waveform crosses zero volts. This minimizes electrical noise and RFI, making it ideal for controlling resistive loads and ensuring longevity.
