Durakool Mercury Relays Available in 1-, 2- and 3-pole versions with capacities from 30 to 150 amps per pole, Durakool mercury displacement relays (MDRs) offer reliable, on-off power switching. MDRs provide longer service life than electro mechanical relays (contactors). We are not able to ship these to certain states, like California.  Please call for availability. Solid State relays or SCR's are a good choice for replacing these relays. We have the experience to assist you with sizing the proper SCR.   Contact Seagate Controls for more information
Solid-State Relays and SCR's These solid-state switches have no moving parts. They are designed to fit into the same space as a mercury relay and perform the same function but without mercury. We carry a complete line of SCR's at Seagate Control Systems. Call us for assistance in sizing and fusing.   Contact Seagate Controls for more information
