Over Temperature Fuse

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.

    • ZZ3
    • Name: Btt Series Thermal Fuse
      Product Description: When fuse body and its ambience temperature rises to the melting point of the orgnic 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: 1.Product of organic compound type; 2.Temperature band is rich(73-240C); 3.Accurate action temperature; 4.Not recoverable.
    • Name: 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: 1.Environmentally fusible alloy type; 2.Plastic case; 3.Accurate action temperature; 4.Not recoverable.

    • Name: Ksd02 Thermal Protector Series
      Product Description: Temperature rise: Heat is transferred to bimetallic strip to reach the operating temerature value, and the contacts are disconnected. Temperature drop: Bimetallic strip quickly restored to original state, contact closed and circuit connected.
      Product Characteristics: 1.Small size, easy for installing; 2.PBT case, metal case, epoxy seal; 3.Auto reset bimetallic strip, usage count more than 10000 times; 4.Moistureproof, dustproof, anti soaking paint; 5.Superior thermal response, double protection for current & temperature; 6.Customized base on customers & requirements.
    • Name: 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 temperatuerdrops to the rated reset temperature, the bimetal sheet element automatically restores the circuit to be connected. 
      Product Characteristics: 1.May operation current 16A; 2.100,000 million times long life; 3.Quick action; 4.Superior thermal response; 5.Ceramic high temperature resistant bracket.
