FSTB KSD302 25A electric heater thermostats, (7/8") bimetal thermal
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.
Advantages:
- Easy mounting.
- Rapid heat transmission.
- High durability, high loading capacity.
- No breakdown, no flashover.
- Every heavy-duty thermostat will be tested, extremely high temperature pass rate.
- High precision.
