Mercury Contactor Relays – 60 Amp Series

Mercury Displacement Relays are all designed and built to meet the most exacting demands of industry. They have won their high place in the electrical field by doing the tough and tricky jobs that ordinary equipment could at best do in an uncertain manner. They have proved their ability to stand up under the most adverse conditions of temperature, dust and moisture, in all types of applications.

The 30-AMP model is designed to save space and simplify mounting methods. The universal three pole mounting bracket has various mounting holes and key hole slots to meet a variety of mounting centers. The 30-AMP series is a more compact line with a well proven switch which is the heart of mercury relays. It is the same switch design that is in our 35 and 60-AMP encapsulated MDR’s, which have withstood the test of time and millions of cycles in many different applications.
