10A 250V 135 Celsius Normal Closed Ceramic Thermostat KSD301 KSD302 For Microwave Oven

 KSD301 Description

KSD301 , thermal protector is a kind heating protector with an open structure. It is ideal protectors for pet drier, industrial heating gun, and heaters, etc, for its prompt snap action and accurate cutout temperature.

At the heart of the device is a bimetal snap-action disc. When the temperature of this disc reaches its pre-calibrated temperature, it snaps open, resulting in an open circuit. This temperature is reached during a fault condition caused by an increase in ambient temperature. After the device breaks the circuit, the system cools and automatically resets allowing power to be restored to the circuit.

Contact capacity:

20A /24VDC 20A /125VAC 12A /250VAC

Temperature specification:

Open temperature: 50~150±5℃; one gear every 5℃.

ON-OFF differential >10℃

Cycles: 6000 cycles @ rated current and voltage.

The principle of this button like thermal protector is that ,the bimetal which is key component of this device

sensed the temperature of the corresponding machine, when the temperature it sensed increased to the

rated action temperature, the bi-metal will snap action in very short mment. When bimetal snap action ,it will

push the active contact point to take action ,in this way, the circuit is on or off .

• Installation Introduction : When we apply this device to target elctric equipment, make sure the holder 
• cling closely to the equipment heating part. To make sure superior temperature sensitivity , thermally
• conductivesilicone or other similar heat conducting medium should be coated on the thermal conducting surface .

 

  

 

• When installing, the cap should not be crushed ,loose ,out of shape.

 

• Liquid should be avoid from permeate into the inside of thermal protector .

 

• When the product hereof is applied in circuit where current is not over 5A , the copper core section of the electric cable is 0.5 - 1mm2 ; when applied in circuit where current is not over 10A , the copper core of the elctric cable is 0.75-1.5mm2 .
