CNL 100A DC48V/AC125V fuse

The CNL 100A is a circuit protector rated for 100 amps at up to 48 volts DC or 125 volts AC. It is built for automotive and low-voltage electrical systems that require reliable overcurrent protection. The RQD-1 designation identifies the specific fuse format for direct replacement.

Suits 100A DC or AC circuits

This fuse suits installers protecting wiring and equipment on 48V DC or 125V AC lines where a 100 amp rating is specified. It is not for circuits that exceed either voltage, for systems needing a different ampere value, or for applications that require a blade or cartridge form factor instead of the CNL series.

100 amp rating decides fit

The single specification that determines compatibility is the 100 amp rating combined with the 48V DC and 125V AC limits. Verify that the circuit design calls for exactly this current and voltage range before fitting the CNL 100A protector.

Questions about this item

Should I choose the CNL 100A rated for DC 48V or AC 125V?

This single CNL 100A unit carries both ratings; it is approved for 100 amps at up to 48 volts DC and 125 volts AC, so one fuse covers either supply.

What does the 100A rating mean once the fuse is installed in a vehicle circuit?

The fuse will carry continuous loads up to 100 amps and will open to protect wiring if current exceeds that value, whether the system is 48 V DC or 125 V AC.

Does the RQD-1 designation limit the fuse to a specific blade or bolt standard?

RQD-1 identifies the CNL series form factor; the fuse fits standard CNL holders and is rated for 48 V DC and 125 V AC at 100 A.
