Solid state relay,SSR,3 phase solid state relay SCR3-DA

Solid state relay,SSR,3 phase solid state relayProduct Description
3 phase solid state relay features
1. Enhanced type is suitalbe for resistive or low current inductive load.
2. Simple installing and wiring connection.
3. Zero-crossing triggering,eliminates the surge current completely.
4. Adopt imported components,endure high current and voltage Pretty structure match safe and high quality requirement.
5. Select high quality SCR,DCB ceramic substrate and SMT technics.3 phase solid state relay main marameters
