Reliable KSD302 Thermostat Gas Hot Water Heater Thermostat
Product Description
KSD302 snap-action big current gas water heater thermostat is a
kind of hermetically sealed bimetal big current thermostat(7/8"
disc). It is of single-pole single-throw structure and works under
resistive load. Owing to high loading capacity, the product KSD302
series gas water heater thermostat is appropriately used in
high-duty electric appliances to provide overheating protection.
