DIN Rail Mount SSR Solid State Relay

All-in-one SSR solid state relays with heat sink and DIN rail mounting are of high strength, impact resistance and strong vibration resistance, with low requirement for input current. They feature 10A, 25A, 40A, 50A, 60A, 80A load current (other load current can be customized), DC to AC, AC to AC and DC to DC control mode. Since this industrial relay mounts on the standard 35mm DIN rail installation with other DIN rail mounted components is quick and easy.

The SSR offers a reliable switching the commercial and industrial loads, is widely used to control computer peripheral devices, thermostats and resistance furnaces, AC motors, intermediate relays and solenoid valves, copiers and fully automatic washing machines, signal lights, traffic lights and scintillators, lighting and stage lighting, CNC remote control systems, automatic fire protection and security systems, high-power thyristor triggering and industrial automation equipment, etc.

Note: The above selection table is only for single phase DC-AC, single phase AC-AC SSR relay. If you need DC-DC type relay, please confirm the load parameters.


  • When choosing an SSR, please notice the actual load current and working ambient temperature.
  • Apply heat-radiation silicon grease of a heat conductive sheet between the SSR and heat sink.
  • Tighten the SSR terminal screws properly.
  • Please do not use the relay beyond the descriptions in the data sheet.
