High-Quality Over Temperature Fuse Supplier, Factories
Overtemperature fuses are critical safety devices used to protect electrical equipment from overheating. They are primarily categorized into two types: OT-F (one-time fusible temperature fuse) and OT-S (resettable thermal switch). The OT-F fuse is designed to permanently disconnect the circuit when the temperature exceeds a predetermined threshold. This one-time use characteristic makes it ideal for applications where a single failure point is acceptable. Once the OT-F fuse has blown, it must be replaced to restore functionality. This type of fuse is widely used in LED lighting,Transformers,Electronic Components,Large Household Appliances,Small Household Appliances,Electric Heating Appliances,and motors. On the other hand, the OT-S fuse operates differently. It is a resettable thermal switch that interrupts the circuit when the temperature rises above a specified limit. However, once the temperature returns to a safe level, the OT-S automatically resets, allowing the circuit to reconnect without the need for replacement. This feature makes OT-S fuses particularly suitable for applications like LED Lighting, Transformer, Motor,Battery,Hair Dryer,Heater,Oven and charger.Â
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 (73-240C)
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
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 installation
PBT/Metal case, epoxy seal
Auto reset bimetallic strip
10,000+ usage count
Moisture & dustproof
Dual current/temp protection
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, pushing the moving contact to disconnect the circuit. When the temperature drops to the rated reset temperature, the bimetal sheet element automatically restores the circuit connection.
Product Characteristics
Operation current: 16A
100 million times life
Quick action response
High temp ceramic bracket
Frequently Asked Questions
1. How does the Btt Series Thermal Fuse operate?
The Btt Series uses an organic compound that melts when the ambient temperature reaches a specific point. Once liquid, spring elasticity pushes the contacts apart to cut off the electrical current.
2. What is the temperature range for Btt Series Fuses?
The Btt Series offers a rich temperature band ranging from 73°C to 240°C, ensuring accurate action for various thermal protection needs.
3. Is the Ksd02 Thermal Protector recoverable?
Yes, the Ksd02 series features an auto-reset bimetallic strip. Once the temperature drops, the strip restores to its original state, closing the contact and reconnecting the circuit automatically.
4. What makes the Atm Thermal Cut-Out Series durable?
The Atm series is designed for long-term reliability with a lifecycle of up to 100 million operations and features a ceramic high-temperature resistant bracket for superior durability.
5. Can the Ksd02 series be customized?
Yes, the Ksd02 Thermal Protector Series can be customized based on specific customer requirements regarding installation and thermal response needs.
6. What is the main difference between Bta and Btt series?
The Btt series utilizes an organic compound type, while the Bta series uses an environmentally fusible alloy type. Both are non-recoverable and provide accurate action temperatures.
