KSD302 Snap Disk Thermostat Switch For Electric Welding Machine

250V High Current Snap Disk Thermostat Switch For Electric Welding Machine

Quick Detail:

Description:

KSD302 series Snap Disc Thermal Switch is to bring the double shell fully enclosed metal contact temperature type temperature relay, according to heat bilges cold shrink principle make sheet metal bending, to set off the temperature, temperature drop can be manually reset after, on electric up security role. KSD302 is widely used for electric welding machine, electric water heater, air compressor, heating and ventilation equipment, vending machine, clothes dryer and heating machine, etc.

1. KSD302 large current thermostat’s specification

(1) Function: temperature protection and overheating protection, prevent dry heating

(2) The electrical characteristics: AC250V ~ 400 V / 15 A ~ 60 A

(3) the highest environment temperature: 180 °C

(4) working temperature range: 0 °C ~ 250 °C (optional). Temperature tolerance: ± 5

(5) Normal headscarf insulation resistance: > 100 M Ω

(6) normal contact resistance: more than 100 m Ω

(7) service life: > 50000 times

2. 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.

Competitive Advantages:

1. Small size and expedient installation

2. High temeprature resistance

3. High reliability, Durable

4. Long life cycles

5. ROHS compliant

6. Wide application

Installation and Direction for Use:

Method of earth: By means of the metal cup of thermostat connected in the earthing metal part.
The thermostat should work in environment with humidity not higher than 90%, free of caustic, flammable gas and conducting dust.
When the thermostat is used to sense the temperature of solid items, its cover should be clung to the heating part of such items. Meanwhile, heat-conducting silicon grease, or other heat media of similar nature, should be applied to the cover’s surface.
If the thermostat is used to sense the temperature of liquids or steam, it is strongly recommended to adopt a version with stainless-steeled cup. Moreover, cautious measures should be taken to prevent liquids getting into/onto the thermostat’s insulation parts.
The top of the cup must not be pressed to sink, so as to avoid adverse effect on the thermostat’s temperature sensitivity or its other functions.
Liquids must be kept out of the thermostat’s inner part! The base must avid any force that could lead to crack; it should be kept clear and away from the pollution of electric substance to prevent insulation weakening that leads to short-circuited damages.
The terminals should be bent, or else, the reliability of electric connection will be influenced.
