Watlow E-Safe Relay

E-Safe Power SwitchThis mercury-free relay from Watlow provides reliable and accurate power switching for processing applications.

 

This relay can exceed the performance of typical mercury relays while fitting within the same footprint to bridge the gap between mercury displacement relays (MDRs) and solid state relays (SSRs) by providing superior power switching in a non-mercury solution.

 

Performance Features

      • Up to 40 amps
      • 240V!(ac)
      • High current transient suppression
      • High reliability
      • Extended contact life
      • Low electrical noise
      • Outperforms mechanical contactors
      • Compact size
      • Easily retro-fittable
      • Environmentally safer than mercury contactors
      • Agency approvals
