3 Phase Solid State Relays

When there is a need for electronically switching off circuits with pre-determined conditions like a timer circuit, electronic relays such as 3 Phase solid state relays are used. More recently, electronic relays are found in various applications and household appliances such as professional cooking equipment, packaging machines, lighting systems, laboratory and medical equipment, HVAC system, and many others. In addition, electronic relays are typically used for industrial on/off control heating applications.
