*Material safety data sheet available on request

*Dispose of properly

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.

Optional DIN rail adaptors – 1 pole = 16-MDRDIN-1, 2 or 3 pole = 16-MDRDIN-2/3
