Sudden jump thermostat Characteristics :

Stable performance , high accuracy , small size , lightweight , high reliability , long lifespan , less interference to radio

Structure and application :
KI-31 serial products are the temperature controllers taking bimetallic strip as the temperature-sensing unit

. In case of normal operation the electrical appliance , the bimetallic strip is in a free state ; the contact  

point is in a state of close/open . When the temperature reaches the action temperature , the bimetallic

strip performs quick action generates caused by internal stress due to heating ; open / close the contact

point ; disconnect / connect the circuit ; thus , the temperature is in control . When the electrical appliance

is cooled to the recovery temperature , the contact point automatically opens / closes to recover normal

operation state .

Widely used in electrical heating appliances like water dispenser, water heater, sandwich bread baker,

dishwasher, dryer, sterilizing cupboard , micro-wave oven, electric heating coffee pot , electric cooker,

refrigeratory , air-conditioner , laminator , heater of auto seat .

Product Structure:

Precautions :

1.When adopting contact temperature sensing installation, the surface of the metal cover is required to be

securely contacted with the installing surface of the controlled device . For ensuring the temperature

sensing effect , it is required to coat thermal conductive grease or other similar thermal conductive medium

on the surface of temperature sensor .

2.For reliable performance , collapse, loose or distorted top part of the cover is prohibited during

installation .

3.Liquid inleakage into the controller, crackle in the casing and unauthorized change of external terminal

position are prohibited . 

4.When the product is used in the circuit with maximum current of 5A , the cable with copper core at section

0. 5-1mm2 is required for connection ; When the product is used in the circuit with maximum current of 10A

, the cable with copper core at section 0.75-1.5 mm2 is required for connection ; 

5.The product should be kept in a clean , dry and corrosive gas-free warehouse with good ventilation and

at relative humidity below 90% , environment temperature below 40 .
