SEFUSE SM-A One Shot Thermal Fuses

Our SEFUSE SM-A thermal fuse is a general purpose, one-time temperature fuse which uses a fusible solder alloy (held inside its ceramic case) as its temperature sensing element.  Once it reaches its precise melting point, the solder alloy melts and thus interrupts the electrical circuit.

These small bodied fuses can be readily incorporated in batteries or motor, transformer and solenoid coils to help provide ultimate over-temperature protection.  When correctly applied, the SM-A thermal fuse can help to prevent domestic, automotive and industrial electrical equipment from catching fire.
