KSD302 25A Big Current Bakelite overheating protection electric heater thermostats with CQC/TUV from FSTB(7/8")
KSD302 series snap-action thermostat is a kind of hermetically sealed high current bimetal thermostat (7/8" disc). It is of single-pole single-throw structure and works under resistive load. Owing to high loading capacity, the product series is appropriately used in high-duty electric appliances to provide overheating protection.
