3. Application of KSD302 large current temperature protector

(1) Electric welding machine, electric

(2) Electric equipment,

(3) Electric products,

(4) Steam heater

(5) High power machinery equipment

(6) Demand Water Heaters

4. Attention of KSD302 large current thermostat

(1) By using the contact temperature type when installed, should make metal cap surface adhere is accused of mounting surface of the appliance.

(2) When installation shall not cover surface pressure deformation, lest affect performance.

(3) To prevent leakage, when using, can't let the fluid infiltration within the thermostat, lest affect electric reliability.

(4) This product for bipolar type wiring way, when using, according to mark symbol, correct connection.

The product should be a headscarf in relative humidity is less than 90%, the environment temperature below 40 ℃ ventilation, clean, dry, no corrosive gas storage in the warehouse.


Thread copper head thermostat / Thread copper head thermal protector

1. Thread copper head thermostat’s Principle and structure

Utilize overseas high-quality dished dual metallic piece as temperature gathering element, will switch installed in water temperature the temperature sensitive parts, dynamic collection the temperature change of the water tank, through the disc in metal temperature deformation, and transient temperature points in beating principle, with institutions in the role of the two contacts quickly switched on, start fan, cooling water of the water, of automobile engine have security role.
