INSTALLATION TIPS
When installing thermal cutouts, it is important to
ensure good heat transfer. The heat sensitive surfa-
ce (base) should be placed on/near to the heat sour-
ce. Heat conducting paste or paint will improve heat
transfer.
It should be noted that standard version thermal cut-
outs have a current-carrying housing, and that with
electrically insulated cutouts the impaired heat
transfer can alter the effective switching temperatu-
re. This should be borne in mind when selecting the
nominal response temperature.
With single-phase motors, the cutout should switch
the mains supply. It will then switch the motor off if
there is any undesirable heating. The motor short
circuit current will then be safely interrupted, if this is
larger than the current rating of the cutout.
For three-phase motors, the motor current will not be
interrupted direct from the mains supply. The cutout
installed in the windings should switch in series with
the magnetic coil of the contactor. The electrical
supply to the cutouts should lead either singly or
together from the motor terminals so that connection
with the control circuit is possible.
