MIDI® style BF1® Slo-Blo® 32V Automotive Bolt-Down Fuse

This BF1 fuse is rated at 32V and offers a bolt-on fuse for high current wiring protection. Current rating 23A - 200A; with transparent housing for easy detection of blown fuses.

Help	Property	Value
It is established by Littelfuse as a value of current which the fuse, fuseholder, fuse clip or other fuse accessory can carry, based on a controlled set of test conditions. Close Info	Ampere Rating (A)	23
Refers to how rapidly the fuse responds to various current overloads. Fuse characteristics can be classified into three general categories: very fast-acting, fast-acting or Slo-Blo® (time delay)fuse. The distinguishing feature of Slo-Blo fuses is that these fuses have additional thermal inertia (surge withstand) designed to tolerate normal initial or start-up overload pulse. Close Info	Opening	Yes
RMS Surge (Non-repetitive) On-state Fusing Current- Measure of let-through energy in terms of current and time for fusing purposes. Close Info	Nominal Melting I²T (A²sec)	1400
Cold resistance is the resistance obtained using a measuring current of no more than 10% of the fuse's nominal rated current. The factory should be consulted if this parameter is critical to the design in question. Close Info	Nominal Cold Resistance (Ohms)	0.0035
Nominal Voltage Drop (mV) Close Info	Nominal Voltage Drop (mV)	105
Color or Alpha-Numeric code used to define the amp rating of the device for ease-of-maintenance and quality checks. Close Info	Marking Code	Tan
