Hello,

Can you provide me the details whether the STEF05P electronic fuse is UL certified or not?

I need to use the component in a device where the safety related components should be UL certified.

Awaiting response.

Best Regards,

Sushant Rajbhar

Please do not confuse the function of an electronic fuse with a classic mechanical fuse.

The STEF05 is an electronic fuse that limits or interrupts the output depending on the current status and its temperature. The authorities normally expect complete separation for safety-relevant circuits.

No, the STEF05 is not UL certified.
