2 Pole SSR Quote - Not seeing what you need?
This product is intended to replace mechanical contactors especially when switching is frequent. The smallest product width in the range is 2.13" (54mm) (3xDIN) and goes up to 2.84" (72 mm).
Switch ON occurs at the voltage zero cross and switch OFF occurs at the current zero cross. Apart from resistive and slightly inductive loads, the SSR is certified for motor switching with associated motor ratings. Varistors are integrated for output over-voltage protection. A green LED gives indication of control voltage presence. Fan operation is controlled for the versions which have an integrated fan.
Detection of SSR overheat, mains loss, SSR malfunction and load loss is possible with the monitored (-M) versions. An EMR alarm output is available for remote signaling. An additional feature with the monitored (-M) is the electronic auxiliary output. The monitored (-M) has additional LED's for load status and alarm status indication.
Specifications are at a surrounding temperature of 77°F (25°C) unless otherwise specified.

MDI Inc. Our Company!
See all MDI Electrical Products
Mercury Displacement Industries Incorporated, better known in the industry we serve as MDI, was incorporated in Michigan in 1975. The primary product line is switch gear components including mercury type contactors, tilt switches and liquid level float controls.
Contactors are rated from 30 to 100 Amperes and 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. All basic units are UL, CSA, and CE approved.
The liquid level control floats are manufactured with mechanical or mercury switches. The float material is High Impact Polystyrene for normal alarm, sump pump or water applications, For sewage, 1 or 2 H.P. or high temperature, 86°C (186°F) requirements Acrylonitrile Butadiene Styrene, (ABS) float material is provided.
MDI has 40 to 50 employees and markets products through distributors, representatives or direct to OEM accounts throughout the world.
