• 35/60 Series - Mercury Displacement Power Relays

The M35 & M60 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 & M60 series offers superior long life performance. Products are available with 1, 2, or 3 poles rated 35 & 60 amps in Normally Open and Normally Closed configurations . 


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