| Thermal Cutout Temperature Protection for Coils/Windings FEATURES - broad product range for all types of application and load - small size - maximum switch load - good heat transfer - high temperature sensitivity - minimal contact resistance - many approvals F Type B Type DESCRIPTION This thermostat operates as a thermal cutout. A thermally sensitive bimetal snap-element with double contacts (single contacts for type F 11) either opens or closes an electrical circuit by switching at a pre-set response temperature. Reset follows automatically after a considerable drop in temperature. Heat transfer occurs from all sides through convection, radiation or conduction in gaseous or solid media. The circular base plate conducts heat onto the bimetal snap-element, thus also allowing its use as a surface temperature cutout. APPLICATIONS Thermal protection and- under certain conditions - temperature control of electrical machinery and equipment.

If insulation is desired, the standard insulation (class) should be selected for the appropriate response temperature or max. operating temperature. The temperature resistance of the connecting leads allows for the nominal response temperature of the cutout. The leads used are consistent with insulation class and dielectric strength stated.

MOUNTINGS Single screw fixing bracket (CuBe) for use on flat surfaces with full insulation or cap. INSTALLATION TIPS When installing thermal cutouts, it is important to ensure good heat transfer. The heat sensitive surface (base) should be placed on/near to the heat source. Heat conducting paste or paint will improve heat transfer. It should be noted that standard version thermal cutouts have a current-carrying housing, and that with electrically insulated cutouts the impaired heat transfer can alter the effective switching temperature. 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.
