35 & 60 Series - Mercury Displacement Relay
Up to 3PST, 35 or 60 Amp
The 35 & 60 series products are mercury displacement relays. Sealed tubes containing liquid
mercury assure contact surfaces are freshly replenished with every contact movement. Contact
resistance is among the lowest available for any electromechanical relay. The M35 series offers
superior long life performance. Products are available with 1, 2, or 3 poles rated 35 amps. Contacts
can be normally open or normally closed.
