Overtemperature Fuses - OT-F & OT-S Types from China Suppliers and Factory for Safety Protection
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:
- Product of organic compound type
- Temperature band is rich (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 restored to original state, contact closed and circuit connected.
Product Characteristics:
- Small size, easy for installing
- PBT case, metal case, epoxy seal
- Auto reset bimetallic strip, 10,000+ uses
- Moistureproof, dustproof, anti soaking paint
- Superior thermal response
- Double protection for current & temperature
- Customized per customer 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 operation current 16A
- 100,000 million times long life
- Quick action
- Superior thermal response
- Ceramic high temperature resistant bracket
Frequently Asked Questions
Q
What is the difference between the Btt Series and Bta Series thermal fuses?
The Btt Series uses an organic compound as its fusible element — when the temperature reaches the compound's melting point, it transitions from solid to liquid and a spring mechanism breaks the circuit. The Bta Series uses an environmentally fusible alloy housed in a plastic case; the alloy melts into a sphere under flux surface tension to cut off the circuit. Both are non-recoverable (one-time use) devices.
Q
What temperature range does the Btt Series Thermal Fuse cover?
The Btt Series offers a rich temperature band ranging from 73°C to 240°C, allowing it to be applied across a wide variety of electrical appliances and industrial equipment that require over-temperature protection at different operating levels.
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 automatically returns to its original state, closing the contacts and reconnecting the circuit. It is rated for more than 10,000 operation cycles.
Q
What is the maximum current rating for the Atm Thermal Cut-Out Series?
The Atm Thermal Cut-Out Series supports a maximum operation current of 16A. It is designed for long service life (100,000 million operations), features quick action response, and uses a ceramic high-temperature resistant bracket for enhanced durability in demanding environments.
Q
Are these thermal protection products suitable for customized requirements?
Yes. The Ksd02 Thermal Protector Series specifically supports customization based on customer requirements, including different case materials (PBT, metal, epoxy seal) and operating temperature values. Please contact us with your specific application parameters for a tailored solution.
Q
What types of appliances or equipment are these thermal fuses and protectors used in?
These thermal protection devices are widely used in household appliances (such as hair dryers, electric irons, rice cookers, and coffee makers), industrial motors, transformers, battery packs, and other electrical equipment where over-temperature protection is critical to prevent fire hazards or equipment damage.
