The remote signaling contact monitors the working status of the SPD. It sends an alarm signal when the SPD fails or needs replacement, enabling real-time monitoring and maintenance.

FATECH SPDs feature TUV & CE certification, stable performance, long service life, and professional technical support. They are widely used in PV, industrial, lighting, network, and residential applications with high cost-performance.

Yes, we support OEM and ODM services

SPDs are widely used in residential buildings, commercial centers, industrial factories, solar PV power stations, LED lighting, security CCTV, telecom base stations, data centers, and infrastructure projects.

Effective grounding provides a low-resistance path for surge current to discharge quickly. Poor grounding will reduce protection performance, increase residual voltage, and may cause equipment damage.
