MDI mercury contactors are ideal for extruder and other high power application because of their power handling capabilities and very long life.
Numerous plastics extruders make use of mercury contactors to supply power to the heaters.
Mercury contactors from MDI, which are available through ICD Controls, are ideal for extruder and other high power application because of their power handling capabilities and very long life.
With the initial pricing being competitive and with a capability of millions of cycles, the contactors will save money from the initial purchase and throughout their working life.
The contactors are constructed with a body of hermetically sealed glass and stainless steel, all totally epoxy encapsulated.
This gives an exterior resistant to both impact and moisture.
Inert internal gases prevent excessive arcing between the mercury and metal electrodes, extending the components' life and therefore saving money.
Main benefits of mercury contactors from ICD Controls are: very long life, high quality, excellent reliability and outstanding value.
Contactors range in size from 20 to 100A in single-, two-, three- or four-pole configurations with both normally open and normally closed contacts.
Standard coil voltages range from 6 to 250V DC and 24 to 480V AC which cover the majority of applications.
Nonstandard coil voltages are available on request.
