EBARA Submersible Pumps <br />Technical Information <br />Project:Model: ChkÊd: Date: <br />Thermal Protection <br />The motor shall be equipped with a protector such as automatic cut-off device and thermal protector. The motors described <br />below shall incorporate Miniature Thermal Protectors (MTP) which are embedded in the windings. <br />When temperature of the winding raises and reaches the MTP acting point, the motor protection circuit is activated to protect <br />motor from over heat. <br />1.Applicable model <br />Model:DGFU, DLFU, DLKFU, DVFU, DDLFU <br />2. MTP Specifications: <br />Model KLIXON 9700K-66-215 <br />Type of Contact b (Normally-Closed contact Acting-open) <br />Acting Temperature 140<br />5°C (284<br />9°F) <br />Re-setting Temperature 85<br />10°C (185<br />18°F) <br />Capacity of Contact <br />3. Installation: <br />MTP shall be embedded in <br />the stator windings as <br />shown at right· <br />4.
