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.
Parts between electriferous components and non-electriferous ones can bear 2000V (3750V for Reinforced insulation type) 50Hz AC current, which is nearly sine wave, for one minute as bearing test. Resulted no breakdown, no flashover.
With a DC 500V megger, borne DC 500V, the tested value is over 10MW.
Resistance Between Terminals
Normal type: OFF temperature higher than ON temperature.(Normal close) One-shot type: The thermostat switches on at room temperature and it won't be able to reset after switching off.
