Document Number: AS5372A
Project Initiation: 02-04-2013
Project Number:
Revision Number: A
Sponsor Name: Susan Rogers
Title
Fuse, Current Limiter Type, Aircraft
Scope
This specification covers the requirements for current limiter type fuses for use in aircraft primary electrical power systems conforming to MIL-STD-704. These limiters are suitable for use in MIL-F-5373 fuse holders for operation at -54 degrees C to 125 degrees C.
Rationale
To update a historical incorrect reference to 200% melting time that does not exist, therefore the 70% cannot be determined. The original curve MS28938 was scaled incorrectly on the "ampere" axis. It is off by a factor of 10 (i.e. 10 should be 1.0). Proper scaling and call out of the 300% in 4.8.10 corrects the error.
