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, usage count more than 10,000 times
- Moistureproof, dustproof, anti soaking paint
- Superior thermal response, double protection for current & temperature
- Customized based on customers' 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 Fuse?
The BTT Series uses an organic compound that melts at a specific temperature to break the circuit, while the BTA Series uses a fusible alloy that becomes spherical under flux surface tension when it melts. Both are non-recoverable one-time protection devices, but the BTA Series features an environmentally friendly alloy and a plastic case.
Q What temperature range does the BTT Series Thermal Fuse cover?
The BTT Series Thermal Fuse offers a wide temperature band ranging from 73°C to 240°C, making it suitable for a broad range of electrical and thermal protection applications.
Q Can the KSD02 Thermal Protector be reset after it trips?
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 restores to its original state and reconnects the circuit. It is rated for more than 10,000 operating cycles.
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 long service life with up to 100,000 million operating cycles and features a ceramic high-temperature resistant bracket for durability.
Q Are these thermal protection products customizable?
Yes, the KSD02 Thermal Protector Series can be customized based on customer requirements, including case type (PBT, metal, or epoxy seal). Please contact us with your specific application needs for tailored solutions.
Q What types of electrical appliances are these thermal protection devices suitable for?
These thermal fuses and thermal protectors are suitable for a wide range of electrical appliances including motors, transformers, household appliances, heating equipment, and industrial electrical devices where overtemperature protection is required to prevent damage or fire hazards.
