Lead Configurations
TMOV34S
The application examples below show how the monitor lead on the TMOV34S
element has been opened. This signifies that the circuit is no longer protected from transients by the MOV.
Application Example 1
In this case, the LED is normally on, and is off when the
thermal element opens.
Application Example 2
This circuit utilizes an optocoupler to provide
galvanic isolations between the TMOV34S
varistor and the indicating or alarm circuitry.

Application Example 3
This circuit illustrates the use of the monitoring lead of
the TMOV34S
operated when overvoltage protection present. In normal
operation the load switch relay solenoid is powered via the
monitor lead of the TMOV34S
thermal element being activated, the relay will de-activate,
cutting power to the protected circuit and the fault LED will
illuminate.
Please note: Indicator circuits are provided as a
guideline only. Verification of actual indicator circuitry
is the responsibility of the end user. Component
values selected must be appropriate for the specific
AC line voltage service and application.
