Description  Relay Freatures Reduced Interference: SSRs produce significantly less electromagnetic interference (EMI) because they lack contact arcing, the internal sparking caused when mechanical contacts separate. Using zero-crossing technology in 2025 SSRs further minimizes noise by switching only when the AC voltage is near zero. Extended Lifespan: Because SSRs use semiconductor devices (like triacs or MOSFETs) instead of physical levers, they do not suffer from…
