Bi-Metal Options

Self-Hold 7AM performance is dependent upon the applied current as well as temperature. Differenct Bi-metals are incorporated to achieve various performance characteristics. 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 Thermtrol for additional application consideration if the rate of temperature rise exceeds 5°C per second. Use these curves to determine which Bi-Metal may trip in the manner required for your application.

Low Resistance Bi-Metal 70 OHM/cmf

Medium Resistance Bi-Metal 125 OHM/cmf

High Resistance Bi-Metal 468 OHM/cmf

Sleeving

Leads

In order to achieve optimum heat transfer from the protected medium or ambient to the industrial thermostat, the Self Hold 7AM has been designed with the case connected to the bimetallic disc. This feature makes it necessary to electrically insulate the 7AM from the mounting surface. Typically, this is accomplished with a Mylar sleeve marked with the part number. Custom markings and other sleeve materials are available.

Thermtrol's state-of-the-art automated lead processing equipment can produce lead wires to meet customer application needs for overall length, wire type, wire size, terminated connection and stripped length requirements. Standard lead size is 18AWG. 20AWG-14AWG is also available.
