INT69 Motor Overheat Protector

Duwan Environmental Protection Motor Overheat Protector

INT69 AV220V 5A thermal protector

INT69 AC220V 5A

Jiangsu Du'an Environmental ProtectionThe INT69 motor overheating protector is specifically designed for monitoring the temperature of the stator winding inside a submersible pump. When abnormal temperature conditions occur in the stator of the pump, the control relay emits the corresponding control signal to allow staff to handle the water pump. The controller incorporates a series of anti-interference measures in its circuit design, enabling reliable operation in environments with severe electromagnetic interference.

Cautionary Notes

When using contact type temperature sensing installation, the product should be tightly pressed against the installation surface of the controlled device.

2. Do not crush or deform the plastic or metal housing during installation to avoid affecting performance.

3. Metal housing products with added insulating sleeves must not have the external insulating sleeve removed or damaged during installation, to prevent leakage and ensure safe operation.

4. When used in circuits with currents not exceeding 5A, the wire should be connected with a copper core cross-section of 0.4-0.75 mm².

5. Products should be stored in a well-ventilated, clean, dry environment with a relative humidity below 90% and a temperature below 40℃ to prevent corrosion.

Cardboard packaging, including product manual, certificate of conformity, and product circuit diagram.
