• 【Stable & Accurate Performance】 Precise temperature response with consistent operating characteristics, suitable for safety-critical applications
• 【Wide Application Range】 Ideal for rice cookers, electric kettles, aroma diffusers, humidifiers, power adapters, heating modules, and small home appliances
• 【Quality-Controlled & Traceable】 Manufactured under strict quality control with batch traceability, supporting long-term and stable supply (model dependent)

📦 Product Description

A Thermal Fuse, also known as a Thermal Cutoff (TCO), is a safety device designed to protect electrical equipment from overheating.

When abnormal temperature rise occurs, the fuse activates at the preset temperature and immediately interrupts the power circuit, preventing further heat buildup and potential hazards.

This component is widely used in household appliances and electronic products where thermal safety is essential.
