Leads
Thermtrol’s state-of-the-art automated lead processing equip-
ment can produce lead wires to meet customer application needs for
overall length, wire type, wire size, terminated connection and
stripped length requirements.

Sleeving
In order to achieve optimum heat transfer from the protected
medium or ambient to the thermostat, the 7AM has been designed
with the case connected to the bimetallic disc. However, this feature
makes it necessary to electrically insulate the 7AM from the mount-
ing surface. Typically, this is accomplished with a Mylar sleeve
available in 0.006 inch thickness, and marked with the part number.
Custom markings and other sleeve materials can also be provided.
Bi-Metal Options
7AM performance is dependent upon the applied
current. In applications where temperature rise is less than 2°C per
second, use low-resistance ratings. High-resistance Bi-Metal is
recommended for applications with 2°- 5°C per second rates of
temperature rise. Contact the factory for additional application
consideration if the rate of temperature rise exceeds 5°C per
second. Use these curves to determine which Bi-Metal will trip in the
manner required for your application.
