Cautionary Notes:
Each product should be carefully evaluated and tested for their suitability of application. 1.Operation beyond the specified maximum rating or improper use may result in damage and possible electrical arcing and/or flame. 2.PPTC device are intended for occasional overcurrent protection. Application for repeated overcurrent condition and/or prolonged trip are not anticipated. 3.Avoid contact of PPTC device with chemical solvent, including some inert material such as silicone based oil, lubricant and etc. Prolonged contact will damage the device performance. 4.Additional protection mechanism are strongly recommended to be used in conjunction with the PPTC device for protection against abnormal or failure conditions.
