What this fuse protects
This OEM Industries CNN 125A fast blow fuse provides circuit protection for automotive and generator electrical systems. It is designed for installers and technicians who need a reliable over-current device rated for both DC and AC voltages. The component interrupts fault current quickly to protect downstream wiring and equipment.
The rating that decides fit
The fuse carries a 125 ampere rating with a maximum voltage of 48 volts DC and 125 volts AC. Verify that the circuit’s normal current and prospective fault current stay within these limits before specifying this part. Using the fuse outside these ratings can cause nuisance blowing or failure to interrupt.
Installation notes
The fuse installs in a compatible CNN series holder or block; no special tools are required beyond standard hand tools for the mounting hardware. Ensure the holder is rated for the same voltage and current class. A common error is re-using a holder with corroded contacts, which adds resistance and causes premature opening.
