Mercury Displacement Relays / Contactors are ideally suited for use with electric heaters or any other rapid switching application. We also carry the H Series for Inductive Loads. (See Other Blog) The below contactors are for 35 amp loads, single or three phase resistive loads. Part number with a -18 are the same as the below. The -18 was an option for a metal strap in lieu of plastic. The plastic is no longer available so all units are in a sense the -18 units.
