10-Pack RF250V 10A 185°C Ceramic Thermal Cutoff Fuse
10-Pack RF250V 10A 185°C Ceramic Thermal Cutoff Fuse
10-Pack RF250V 10A 185°C Ceramic Thermal Cutoff Fuses — Keep Your Appliances Safe
These RF250V ceramic thermal cutoff fuses are essential components for protecting household and commercial appliances from overheating. Rated at 10A / 250V with a 185°C trip temperature, each fuse is engineered for stable, precise one-time operation — automatically interrupting the circuit the moment temperatures exceed the safe threshold. The ceramic pipe construction protects the sealing resin from mechanical stress during lead bending, making installation straightforward and reliable. Made in Mainland China.

Frequently Asked Questions
Q: What does a thermal cutoff fuse do in a rice cooker or appliance?
A: A thermal cutoff fuse (TCO) is a one-time safety device embedded in appliances. When the internal temperature reaches 185°C, the fuse permanently interrupts the electrical circuit, preventing further current flow and protecting the appliance from heat damage. This RF250V 10A fuse is commonly used in rice cookers, kettles, irons, and other household appliances as a built-in safeguard.
Q: Can I replace a blown thermal cutoff fuse myself?
A: Yes — these RF250V ceramic thermal fuses are designed for straightforward replacement. Simply locate the old fuse in your appliance (usually near the heating element), note the specifications (voltage, current, and temperature rating), and solder in the replacement with matching specs. Always ensure the appliance is unplugged and fully cooled before attempting any repair. If you are unsure, consult a qualified technician.
Q: Are these fuses compatible with 220V/240V appliances?
A: Yes. These fuses are rated at 250V, making them suitable for use in both 110–120V (North American) and 220–240V (European/Asian/Australian) appliances, provided the current draw does not exceed 10A. Always verify the original fuse specifications in your appliance before replacing.
Q: Why buy a 10-pack instead of a single fuse?
A: Thermal cutoff fuses are single-use components — once they trip, they must be replaced. Having a 10-pack on hand is ideal for repair technicians, DIY enthusiasts, and anyone who regularly services appliances. It ensures you always have a spare ready and offers better value per unit.
