Overtemperature Fuses: China Factory Suppliers of OT-F and OT-S Thermal Switches for Electrical Safety
Btt Series Thermal Fuse
Product Description
When fuse body and its ambience temperature rises to the melting point of the organic compound, the compound changes from solid state to liquid state. Under the action of spring elasticity, the contact is pushed off to cut off the current.
Product Characteristics
- ✔ Organic compound type
- ✔ Temperature band 73–240°C
- ✔ Accurate action temperature
- ✔ Not recoverable
Bta Series Thermal Fuse
Product Description
When fuse body and its ambience temperature rises to the melting point of Thermal fuse, the alloy is spherical fused under the surface tension of flux, cutting off the circuit and playing a protective role.
Product Characteristics
- ✔ Environmentally fusible alloy type
- ✔ Plastic case
- ✔ Accurate action temperature
- ✔ Not recoverable
Ksd02 Thermal Protector Series
Product Description
Temperature Rise: Heat is transferred to bimetallic strip to reach the operating temperature value, and the contacts are disconnected. Temperature Drop: Bimetallic strip quickly restores to original state, contact closed and circuit connected.
Product Characteristics
- ✔ Small size, easy to install
- ✔ PBT case / Metal case / Epoxy seal
- ✔ Auto reset — 10,000+ cycles
- ✔ Moistureproof & dustproof
- ✔ Superior thermal response
- ✔ Customizable per requirements
Atm Thermal Cut-Out Series
Product Description
When the temperature of the protected electrical apparatus rises, the heat generated is transferred to the bimetal sheet element, and when the predetermined operating temperature is reached, the bimetal sheet element acts quickly, pushing the moving contact to disconnect the contact, thereby cutting off the circuit; when the temperature drops to the rated reset temperature, the bimetal sheet element automatically restores the circuit to be connected.
Product Characteristics
- ✔ Max operating current 16A
- ✔ 100,000 million cycle long life
- ✔ Quick action
- ✔ Superior thermal response
- ✔ Ceramic high-temp resistant bracket
Frequently Asked Questions
Q What is the difference between the Btt Series and Bta Series Thermal Fuse?
The Btt Series uses an organic compound as its fusible element — when the ambient temperature reaches the compound's melting point, it transitions from solid to liquid and the spring-loaded contact opens. The Bta Series uses an environmentally friendly fusible alloy housed in a plastic case; the alloy melts spherically under surface tension to cut off the circuit. Both are non-resettable (one-time use) devices.
Q What temperature range does the Btt Series Thermal Fuse cover?
The Btt Series offers a wide and rich temperature band ranging from 73°C to 240°C, allowing it to be used across a broad variety of appliances and industrial applications that require precise over-temperature protection.
Q Can the Ksd02 Thermal Protector automatically reset after tripping?
Yes. The Ksd02 Thermal Protector Series features an auto-reset bimetallic strip. Once the temperature drops back to a safe level, the bimetallic strip returns to its original shape and reconnects the circuit automatically. The device is rated for more than 10,000 operation cycles, making it suitable for long-term use.
Q What is the maximum operating current for the Atm Thermal Cut-Out Series?
The Atm Thermal Cut-Out Series supports a maximum operating current of 16A. It is designed for quick action with superior thermal response and uses a ceramic high-temperature resistant bracket to ensure reliable performance even under demanding conditions.
Q Are these thermal protection products customizable for specific application requirements?
Yes. The Ksd02 Thermal Protector Series specifically supports customization based on customers' requirements, including case material options such as PBT, metal case, or epoxy seal. For other series, please contact us directly to discuss your specific operating temperature, current rating, or housing needs.
Q What types of equipment are these thermal fuses and protectors typically used in?
These thermal protection components are widely used in household appliances (such as hair dryers, electric irons, rice cookers, and coffee makers), electric motors, transformers, battery packs, and other electrical equipment where over-temperature protection is critical to prevent fire hazards or component damage.
