Thermal Cutoffs (Thermal Fuses)

A thermal cutoff (or thermal fuse) is a device designed to protect against overheating by automatically shutting off power to an appliance or circuit when the temperature exceeds a predetermined level. This type of safeguard is essential for most electric and electronic systems, and are often found in consumer applications such as air conditioners, refrigerators, water heaters, furnaces, and ovens. Thermal cutoffs are also an important component of high-performance systems such as computers, vehicles, aircraft, and manufacturing processes.

SDF DF066S Application Field and Working Principle

The SDF DF066S thermal cutoff is designed to provide reliable thermal protection for heating systems up to 240V AC and temperatures ranging from -40°C to +195°C. The device is frequently used for industrial-scale applications such as HVAC systems, medical equipment, high-end appliances, food processing machinery, and automotive components. It is also suitable for safety applications such as emergency stop circuits and interlocks.

The device is small and compact, measuring just 60x20 mm with a reaction time of 30 minutes or less. It comprises a metal case with two pins, and a thermal element contained inside. The thermal element is normally kept in an open circuit state and the contacts are held closed by a pair of bi-metallic strips. When the temperature rises above the safe limit, the bimetallic strip will expand from the heat and force open the contacts, breaking the circuit and stopping the flow of current.

The SDF DF066S is also available in an adjustable version, which can be calibrated to trip at specific temperatures within a range. This allows the device to be tailored for specific motors or other appliances and devices, ensuring the most reliable and accurate thermal protection. The device is also heat resistant and resistant to shock and vibration, so it can be used in a wide range of industrial environments.

The SDF DF066S thermal cutoff is an easy-to-use and reliable device for providing effective thermal protection for high-performance systems. It is designed for maximum dependability and is available in both manually adjustable and fixed temperature variants, providing thermal protection within a wide temperature range. With its small size and fast reaction time, the SDF DF066S thermal cutoff is an ideal choice for industrial applications where reliable and accurate thermal protection is essential.
