Product Description

Product Description

Factory Supply Bakelite Bimetallic KSD305 Snap Action Thermostat for High-power Appliances

This is the KSD305 high-power snap-action thermostat, a bimetallic strip temperature-sensing overheat protection switch.

Its core function is "automatic power-off upon overheating, followed by cooling and reset (or manual reset)," making it a critical safety component for high-power appliances.

Its main application scenarios include:
- High-power water heaters: instantaneous electric water heaters, commercial storage water heaters, electric water faucets

  (commonly 95℃ specification with anti-dry-burning protection);
- Industrial/commercial heating equipment: welding machines, steam generators, industrial heaters (suitable for high current handling requirements);
- Kitchen appliances: commercial fryers, large ovens, sandwich makers (high temperature resistance + high current characteristics);
- Equipment for humid environments: bathroom heaters, steam sterilizers (some models have moisture-proof design);
- Other high-power appliances: electric vehicle battery packs, heaters, large water dispensers (high-power equipment requiring overheat protection).

In short, it is a thermostat designed for high-power, high-temperature, high-load equipment, with a stronger load capacity than the ordinary KSD301.
