  • 8 Series - Screw Terminal Power Relays

    The 8 series is a general purpose power relay. It is base mounted with screw terminals, front connected, and has 600 volt spacing. The 8 series is supplied with continuous duty coils, and is suitable for applications ranging from supervisory and interlocking functions to control of small motors, heaters, solenoids or for transferring power from a main auxiliary supply or load.

    Additional contact configurations and coil options are available – please use the RFQ/RFI tab above to submit your request.

    Made in U.S.A.

  • 35/60 Series - Mercury Displacement Power Relays

    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

  • 102 Series - Contactors

    The 102, 200 Amp contactor is a heavy duty relay. Similar to the smaller 100 amp B101 the contactor uses a single pole with double make or double break switching. Contacts are protected in a molded plastic cover. Panel mounting is standard. The powerful electromagnetic structure produces high contact pressure which results in very reliable low resistance contacts for long life. The 102 series are ideally suited for applications in telecommunications, hoist and elevator industries, rail mass transit and others.
