La differenza tra il collegamento del fusibile termico e l'interruttore di interruzione termica

UN “thermal fuse link (Fusible alloy wire and Organic thermal fuse)” is essentially a one-time fusible cut off, heat-sensitive component that permanently breaks a circuit when it reaches a specific temperature. while a “thermal cutoff switch” is a bimetallic strip device that can potentially cut off itself after reaching a high temperature, allowing the circuit to reconnect once the temperature drops below a set point. both are used as safety mechanisms to protect against overheating, but the key difference is the “fuse link” is designed to only operate once, while the “cutoff switch” can potentially cycle multiple times.

bimetallic strip thermal cutoff switch device For electric Fan heaters

Tipo di fusibile termico e interruttore di interruzione termica

Key points about thermal fuse links:
One-time use: Once activated by excessive heat, the fusible link melts and permanently breaks the circuit, requiring replacement.
Simple design: Typically consists of a low-melting point alloy that melts when heated above a predetermined temperature.
No reset function: Cannot be reset manually after activation.

Key points about bimetallic thermal cutoff switches:
Resettable:
When the temperature drops below the set point, the switch contacts reconnect, allowing current to flow again.
More complex design:
Often uses bimetallic strips that bend or expand when heated, causing the switch to activate.
Potential for multiple cycles:
Can be used in applications where temporary overheating may occur, unlike a thermal fuse link.
