New Manual Reset Temperature Controller Overheat Protection Thermostat
KSD301 temperature protector's Principle and structure
The main principle of KSD series thermostat is that one function of bimetal discs is snap action under the change of sensing temperature. The snap action of disc can push the action of the contacts through the inside structure, and then caused on of off the circuit finally. The main characteristic are the fixation of working temperature, the reliable snap action, less flashover longer working life and less radio interference.
2. KSD301 thermostat's specification
2.1. Electrical Rating: AC 125V max 15A; AC250V 5A 10A 15A max 16A
2.2. Action Temperature: 0~250 degree
2.3. Recovery and action temperature difference: 10 to 25 degrees, or according to client's request.
2.4. Temperature deviation: ± 3 / ± 5 / ± 10 degree or according to client's request
2.5. Circuit resistance: ≤ 50MΩ (Initial value)
2.6. Insulation resistance: ≥ 100MΩ (DC500V Normal State)
2.7. Dielectric Strength: AC50Hz 1500V / min, no breakdown blinding (Normal State)
Life cycle: ≥ 100000
2.8. Normally closed or open
2.9. Two kinds of mounting bracket: Movable or fixed
2.10. Terminal
A. Terminal type: 187 series of 4.8*0.5mm and 4.8*0.8mm, 250 series of 6.3*0.8mm
B. Terminal Angle: Bending angle: 0~90° C optional
2.11. Two kinds of body: Bakelite or ceramic.
2.12. Two kinds of temperature sensor face: Aluminium cap or copper head.
