Mercury Contactor Relays – 35 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 35-AMP normally open contactors are designed and manufactured to high quality specifications and the contactors are commonly used in various heating, lighting, and many other industrial applications including high voltage ultraviolet type loads. The contacts are encased in hermetically sealed stainless steel tubes to provide reliable switching for millions of operations. MDI has manufactured this contactor since 1975. It is available in the single, two, three & four pole models.
