Zelio™ SSP solid state relays are 3-phase panel mounted relays with IP20 housing. The SCR outputs allow them to be used in various power switching applications. These power relays with 25 A and 50 A current rating are EMC compliant. SSP relays are integrated with an R-C snubber circuit and TVS (transient voltage suppression). They are available with zero voltage switching for resistive load and random switching for inductive load applications.
