Gold SA3-4025D Three-Phase Solid State Relay

Technical specifications for the Gold SA3-4025D three-phase solid state relay. This device switches three-phase AC loads up to 25 amps per phase within a 40-530 VAC range. Control input accepts 3-32 VDC logic signals with zero-crossing turn-on to minimize inrush current and EMI. Isolation between input and output exceeds 2500 VAC. The relay features an LED status indicator and requires external heat sink mounting for thermal management. Suitable for industrial temperature control, lighting, and motor starting circuits. Manufactured by Wuxi Gold Control Technology Co., Ltd. (Jiangsu Gold Electrical Control Technology Co., Ltd.). Direct replacement for part numbers SA3-4025D and SA34025D. Zero moving parts ensure long operational life and high switching frequency capability compared to electromechanical contactors.
