What gets protected by the thermistor?
"Surge-Gard inrush current limiting NTC thermistors are ideal for switching power supplies where the low impedance of the charging capacitor exposes the diode bridge rectifier to an excessively high current surge at turn-on," said Larry Howanitz, Vice President, EIS & Sensors, API Technologies. "They offer maximum current protection when the power supply is turned on, allowing the design engineer to select lower peak current rated diode bridge rectifiers for use in the switching power supply."

No mention of magnetics, capacitors, or what ever requiring protection.
