2A / 10A COMPONENT THERMAL FUSES

Professional Grade Thermal Fuses High-Precision Circuit Overheating Protection 

Our collection of thermal fuses (also known as thermal cutoffs) provides essential, non-resettable safety protection for a wide range of household and industrial appliances. Designed to permanently interrupt an electrical circuit when temperatures exceed safe operating limits, these components prevent potential fire hazards and equipment damage caused by overheating.
 

Product Series Overview

We offer three distinct series of thermal fuses categorized by their maximum current rating to suit various applications:

1. Low Power Series (2A Rating)

Ideal for small electronics, transformers, and delicate circuit boards where precision is critical.

• Temperature Range: $125^{\circ}\text$ to $150^{\circ}\text$.

• Available Variants:

125 (C) -ST, 130 (C) -SL, 130 (C) -ST, 135 (C) -SL, 145(C) – ST, 145(C) -SL, 140 (C) -SL, 140 (C) -ST, 150 (C) -SL, 150 (C) -ST,

•  THERMAL FUSE 10A :

80(C), 85(C), 90(C), 92(C), 95(C), 100(C), 103 (C), 105(C), 110(C), 113(C), 115(C), 119 (C), 121(C), 125(C), 126(C), 130(C), 135(C), 140(C), 145(C), 142(C), 144(C), 150 (C), 152(C), 155 (C), 160(C), 165(C), 169 (C), 172 (C), 175(C), 180(C), 185(C), 192 (C), 195(C), 200(C), 210(C), 216(C), 220(C), 225(C), 226 (C), 227 (C), 229 (C), 230 (C), 240(C), 250(C), 280 (C)

•  THERMAL FUSE 20A :
230(C), 185(C), 200(C), 216(C)

2. Standard Appliance Series (10A Rating)

The most versatile range, commonly found in coffee makers, hair dryers, irons, and kitchen appliances.

• Temperature Range: 80(C) to 280(C)

• Key Increments: Available in nearly every 5(C) step to ensure an exact match for your original manufacturer specifications.

• Specialty Ratings: Includes high-precision values such as 119(C), 142(C), 169(C), 192(C), and 229(C).

3. High Capacity Series (20A Rating)

Heavy-duty protection for high-wattage machinery, industrial heaters, and large electric motors.

• Available Temperatures: 185(C), 200(C), 216(C), and 230(C).
   

Key Features

• Non-Resettable Safety: Once the fuse "blows" due to heat, the circuit remains open until the component is replaced, ensuring the underlying fault is addressed.

• Compact Form Factors:

  • Square/Block Style (SL/ST): Compact design with long leads for easy PCB mounting.

  • Cylindrical/Axial Style: Metal-clad body for superior thermal conductivity in direct-contact applications.

• Fast Response Time: Engineered with heat-sensitive organic materials that react instantly to temperature spikes.

• Durable Lead Wires: High-conductivity leads designed for secure soldering or crimping.
   

Technical Specifications

• Current Ratings: 2A, 10A, or 20A (Model Specific).

• Voltage Compatibility: Supports standard AC circuits (typically up to 250V).

• Housing: Flame-retardant ceramic or sealed metal alloy.
   

Top 3 Customer Questions & Concerns ‍

 How do I know which temperature rating to buy?

Always check the text engraved on your original fuse. Replacing a fuse with a higher temperature rating than specified can be dangerous and may lead to a fire.

Should I solder or crimp these into place?

Crimping is highly recommended. Because these fuses are triggered by heat, the high temperature of a soldering iron can accidentally blow the new fuse during installation. If you must solder, use a heat sink (like a pair of pliers) on the lead wire.

 Can I use a 10A fuse to replace a 2A fuse?

While a higher current rating is technically "safer" in terms of capacity, it may not fit physically. It is always best practice to match the exact original specifications.
