70 AMP Solid State Relay with integrated heatsink

Solid State Relays are advantageous in industrial heating applications requiring high cycle rates. These relays have integral heat sinks and are ready to mount on chassis or DIN-rail. Standard housing dimensions enable straight-forward replacement of alternative products and allow for two standard terminal configurations. Cage clamp terminals are used to ensure secure load connection with cable up to 3 AWG or 2 wires at 6 AWG. An LED indicates the status of the control input. The superior heat-transfer efficiency, combined with a robust power management system, makes this a highly reliable product that can meet the most stringent functional requirements.
