Self-Hold thermal switch 7AM Series for Temperature Protection
Product Description
The Self-Hold 7AM Series Bimetal thermal switch combines the
protection of a Klixon 7AM with a self-holding feature. Designed to
prevent overheating in motors, the Self-Hold 7AM series offers the
best attributes of one shot protectors and auto resetprotectors 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 removepower and the device will cool
and reset.This inherent design feature adds an extra levelof
security over automatic reset devices of any type. It is the
reliable, cost effective solu-tion for numerous applications. Each
7AM temperature rating has a bimetal disc specifically manufactured
for that rating. Each device is then calibrated and checked for
opening temperature. This results in optimum snap–acting open and
reset characteristics necessary to achieve consistent performance
over the required cycle

The Self-Hold 7AM is a Thermal Protector/PTC Heater combination.
The PTC Heater is electrically located across the contacts of the
protector.
When the protector contacts are open, the heater is in series with
the load.The heater then maintains the temperature sensitive
bimetal of the protector in an open state.To reset the Self-Hold
7AM, power must be removed for sufficient time to allow the
Self-Hold 7AM to cool to below the protector's reset point.
