10Pcs Ceramic Thermal Cutoff Fuse 10/15/20A 250V 185°C 230°C
10Pcs Ceramic Thermal Cutoff Fuse 10/15/20A 250V 185°C 230°C
10Pcs Ceramic Thermal Cutoff Fuse — 10/15/20A, 250V, 185°C & 230°C
Keep your home appliances and low-voltage circuits safe with this pack of 10 ceramic thermal cutoff fuses. Engineered with a high-purity ceramic housing and a precision thermal-sensitive alloy core, these fuses deliver reliable overheat protection for everyday household devices like electric kettles, rice cookers, space heaters, and more. Made in Mainland China.
Key Features
- Superior Heat Insulation: High-purity ceramic housing provides exceptional high-temperature resistance, electrical insulation, and impact resistance — protecting internal sensing components from external damage and electrical leakage for a long service life.
- Precise Overheat Cutoff: The thermal-sensitive alloy core triggers an immediate circuit cutoff exactly when the preset temperature (185°C or 230°C) is reached. No false triggers under normal operating conditions — helping prevent appliance burnout and potential fire hazards.
- Stable High-Voltage Conduction: Fiberglass braided insulated lead wires offer excellent anti-aging and heat-resistant performance, maintaining stable conductivity under a 250V rated load — ensuring continuous, reliable current transmission without insulation breakdown or short-circuit faults during long-term use.
- Sealed Corrosion-Resistant Structure: High-density hermetic sealing paired with the ceramic shell blocks moisture, dust, and corrosive substances from reaching internal components — maintaining stable performance even in humid, dusty, or mildly corrosive environments.
- Compact Universal-Fit Design: The thickened mini ceramic body fits most small-to-medium electrical appliance installation spaces and supports convenient soldering assembly, making installation and maintenance straightforward.

Frequently Asked Questions
Q: What is a ceramic thermal cutoff fuse and how does it work?
A: A ceramic thermal cutoff fuse is a one-time-use safety device built into electrical appliances. Its thermal-sensitive alloy core melts and permanently opens the circuit when the surrounding temperature reaches the fuse's rated cutoff point (e.g. 185°C or 230°C), instantly stopping current flow and preventing the appliance from overheating or catching fire.
Q: Can these fuses be used in multiple appliances?
A: Yes. The compact, universal-fit ceramic body is compatible with a wide range of small and medium household appliances — including electric kettles, rice cookers, hair dryers, space heaters, and low-voltage power supply circuits — as long as the voltage and current ratings match your device's specifications.
Q: Are these thermal fuses resettable after they trip?
A: No. Thermal cutoff fuses are single-use components. Once the cutoff temperature is reached and the circuit opens, the fuse must be replaced. This is a deliberate safety design to ensure the appliance cannot be inadvertently restarted without a proper inspection and fuse replacement.
Q: How do I choose between the 185°C and 230°C versions?
A: Choose based on your appliance's maximum safe operating temperature. Check the original fuse markings or the appliance service manual for the correct cutoff temperature. Using a fuse with too high a cutoff temperature may leave the appliance unprotected, while too low a rating may cause nuisance trips during normal operation.
