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)	2
The maximum RMS AC voltage and/or the maximum DC voltage at which the fuse is designed to operate. For example, fuses rated at 600 volts and below may be applied at any voltage less than their rating. There is no rule for applying AC fuses in DC circuits such as applying the fuse at half its AC voltage rating. Fuses used on DC circuits must have DC ratings. Close Info	VDC (V)	450

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	Fast-Acting (F)
Package Size/Form Factor Close Info	Package Size	TE5 (8.9x8.9mm)
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)	0.061
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)	0.094
Close Info	Interrupt Rating	10000A@450VDC
Close Info	Interrupt Rating	300A@450VDC
Close Info	Interrupt Rating	100A@250VAC
Nominal Voltage Drop (mV) Close Info	Nominal Voltage Drop (mV)	273.6
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	E67006
