Glass time-delay fuse for low-voltage circuits
The Bussmann MDL-9-R is a cylindrical glass fuse rated at 9 A and 32 V AC with a 1 kA interrupt rating. It suits automotive, marine or generator wiring where a time-delay element prevents nuisance blows from inrush current. The non-rejection body fits standard 1-1/4 inch by 1/4 inch fuse holders. Supplied in a five-piece pack for spares or multiple circuits.
Practical limits of the 32 V AC rating
The 32 V AC rating restricts use to low-voltage DC or AC systems such as battery banks, generator control panels or accessory circuits. It cannot protect mains-voltage equipment or higher-voltage DC lines. The 1 kA interrupt capacity covers typical short-circuit currents in these applications. Time-delay operation tolerates brief overloads but will not sustain continuous current above 9 A.
The 9 A rating decides fit
Select this fuse only when the circuit’s normal operating current is at or below 9 A and the voltage does not exceed 32 V AC. A higher-rated fuse would fail to protect the wiring; a lower-rated fuse would blow in normal service. Verify the holder accepts the 1-1/4 inch by 1/4 inch glass body before installation.

Questions about this item
Should I pick the 5-pack or buy single fuses for my 9 A circuit?
The 5-pack gives you spares for the same 9 A, 32 V AC rating so a blown fuse can be replaced immediately without re-ordering.
What does the 1 kA interrupt rating mean when the fuse is installed?
It means the fuse can safely break a fault current of up to 1 kA at 32 V AC without rupturing the glass body.
Which fuse series does the MDL-9-R cross-reference for a direct swap?
It crosses to Bussmann MDQ, MDV, MDX, Littelfuse 313, 315, Mersen GDL and GDV series.
