حفاظت مدار فیوز خودبازگشت (پی‌تی‌سی)

Product Attributes

Introduction

Designed for use in a wide range of electronic devices, these thermistor-type devices limit the flow of dangerously high current during fault conditions. But unlike traditional fuses that work one time and must be replaced, Raychem Circuit Protection’s PPTC devices reset after the fault is cleared and power to the circuit is removed. This reduces service and repair costs, resulting in improved customer satisfaction and reduced warranty costs.
