FAQ

What type of fuses should be used with this DF103 holder?

This holder is designed for cylindrical fuses of size 10x38mm. You should use fuses with an appropriate interrupting rating for your application, such as Class aM or gG types, up to a maximum of 32A.

What is the short-circuit withstand rating of this device?

The short-circuit withstand rating depends on the installed fuse. Always pair it with a fuse that has a breaking capacity suitable for the prospective short-circuit current at the point of installation, typically up to 100kA.

Are there any considerations for operating this fuse holder at high ambient temperatures?

Yes, like most electrical components, its current-carrying capacity may need to be derated at ambient temperatures above the manufacturer’s specified reference (usually 40 deg C). Refer to the Schneider Electric technical datasheet for specific derating curves.
