scope:

This specification covers instrument type fuses designed for the protection of electrical, electronic, and communication equipment on direct current (dc) and alternating current (ac) (up to 400 hertz (Hz)) circuits. Statistical process control (SPC) techniques are required in the manufacturing process to minimize variation in production of fuses supplied to the requirements of this specification.

The type designation of fuses shall be in the following form, and as specified (see 3.1 and 6.2).

The style is identified by the letters "FM" followed by a two-digit number, denoting a fuse of a given construction and dimensions.

The characteristic is identified by a one-letter symbol which indicates the relative overload interrupt time (see 6.5) in accordance with table I. TABLE I. Characteristics.

Symbol Relative overload interrupt time ------------------------------------------------ A Normal B Time delay

The voltage rating shall be the maximum direct current (dc) or alternating current (ac) root mean square (rms) voltage for which a fuse is designed (see 3.1). The voltage rating is identified by a numerical value followed by the letter "V".

The current rating is the amount of current a fuse will carry indefinitely without interruption (see 3.1). The current rating in amperes and fractions of an ampere is identified by a numerical value followed by the letter "A".

When specified, a suffix letter shall be added to the type designation covered by selected specification sheets to denote optional finish (see 3.1). Beneficial comments (recommendations, additions, deletions) and any pertinent data which may be of use in improving this document should be addressed to: Commander, Defense Electronics Supply Center, ATTN: DESC-EMM, 1507 Wilmington Pike, Dayton, OH 45444-5283, by using the Standardization Document Improvement Proposal (DD Form 1426) appearing at the end of this document or by letter.

intended Use:

Fuses covered by this specification are intended for use in electronic and low power electrical equipment where relatively low values of short circuit currents are encountered. The fuse primarily... View More
