Appliance Protection - Self-Hold 7AM Series Manual Reset Thermal Protectors
Type B shown
Thermtrol's innovative Self-Hold 7AM
thermal protector combines the protection of a Klixon 7AM with a
self-holding feature. Designed to prevent overheating in a variety
of consumer, industrial, and commercial products, the Self-Hold
7AM offers the best attributes of one shot protectors and auto
reset protectors in a single package. The Self-Hold 7AM, once
activated in a fault condition, maintains its open state until
power is removed. No reset button here- simply remove power and the
device will cool and reset. This inherent design feature adds an
extra level of security over automatic reset devices of any type
and yields test agency classification as a manual reset device. It
is the reliable, cost effective solution for virtually unlimited
applications.

Step 5: Choose Insulating
Sleeve
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 features also makes it
necessary to electrically insulate the 7AM from the mounting
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.
