B: after disconnection, it can withstand AC800V/ 0.5ma, 3S without breakdown and flicker.

4)Insulation resistance: under normal≥100MΩ 

5)contact resistance: ≤50M Ω

6)shell material is bakelite shell

Working Principle of 60A Big Current KSD308 Thermostat

Bipolar jump thermostat is a bimetal thermostat with a shell. The use of disc-type bimetallic film in the role of the moment under the principle of instantaneous beating, through the role of mechanical structure, so that the two groups of contacts quickly action to achieve the same time to disconnect or turn on the purpose of bipolar circuit.

Usage of Water Heater KSD308 Thermostat

Widely used in a variety of electric appliances, such as hot water heater, fast-type (fast-type) electric water heater, water storage type electric water heater, small water heaters, solar water heaters,with overheating protection.

Instructions for Installation and Use

1. Grounding: The metal cover of the temperature controller is connected to the ground metal parts of the device.
2. The thermostat should work in the general indoor environment where the relative humidity of the air is not greater than 90%, non -corrosive gas, flammable gas and electric conductive dust exist.
3. When the thermostat uses contact with the temperature, the cover should be covered with the heating part of the charged appliance, and the thermal conductivity of the heating silicon grease or other performance should be applied on the cover of the temperature.
4. The top of the cover cannot be crushed or deformed to avoid changing the temperature or other performance.
5. Do not let the liquid penetrate inside the thermostat! The shell must avoid excessive power to prevent cracks; the shell should be kept clean to prevent pollution of conductive substances, so as to avoid short -circuit penetration due to the reduction of insulation performance.
6. The use process cannot bend the wiring terminal, otherwise it will affect the reliability of electrical connection.
