Special features of KSD301 Thermostat

Temperature sensing components consist of bimetallic strip. When the temperature reached the action temperature range, it will jump quickly and the movable disc disconnects. When the temperature declines to a fixed temperature point, the contact point cannot reset until reconnecting the circuit by pushing the reset button. And then the contact points recover , reaching a purpose of connecting or disconnecting the circuit and restarting the circuit by manual reset. (Kindly reminder: 1.This type of manual reset thermostat can reset when the temperature declines 20 ℃ after snap action by pressing the reset button. And 4~6 N will be advisable, please don’t use too much strength. 2. To ensure the normal function, the distance between the reset button and the close cover should not be less than 20.4mm. )

Technical parameters:
1.Electrical parameters: 1)CQC,VDE,UL,CUL AC250V 50~60Hz 5A/10A/15A (Resistance load)

9.Junction method: Constant-closed: the contact point disconnects when temperature rises; and contact            point connects when temperature falls;
  Constant-opened: the contact point connects when temperature rises; and contact point disconnects when temperature falls.
10.Casing protective class: IP00
   Installation method: installed for KI031 series: general moving ring, mini round moving ring, flat moving ring general aluminum cover with mounting hole, extra length aluminum cover with mounting hole.

Precautions:
1.Grounding method: Connection is made between the metal casing of the temperature controller and the metal part of the grounding device.

2. 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.
3. For reliable performance, collapse, loose or distorted top part of the cover is prohibited during installation.
4. Liquid inleakage into the controller, crackle in the casing and unauthorized change of external terminal position are not allowed.
5. 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;
6. 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℃.
7. Do not bend the terminals when installation, otherwise it will affect the reliability of the electrical connection.
