MIL-PRF-17773C(SH)
6. NOTES
(This section contains information of a general or explanatory nature that may be helpful, but is not mandatory.)
6.1 Intended use. Switches are intended for use in applications as devices that automatically or manually
transfer power supply lines to a connected load. When accomplished automatically, control circuits determine when
and in what manner the transfer will occur.
6.2 Acquisition requirements. Acquisition documents should specify the following:
a.
Title, number, and date of the specification.
b.
PIN (see 1.3).
c.
d.
Instruction sheets (see 3.2.15).
e.
Adjustable configuration settings, if required (see 3.2.16).
f.
Different weight and size requirements (see 3.3).
g.
Special features (see 3.4.1).
h.
Operating voltage (see 3.4.2.3.3).
i.
j.
Timing or time delay, other than as specified (see 3.4.2.3.6).
k.
Operating frequency (see 3.4.2.3.11).
l.
Special frequency variation or time delay requirements for frequency sensing ABTs (see 3.4.2.3.11).
m. Full or single phase protection for ABTs (see 3.4.2.3.12).
n.
In-phase monitoring control circuit for ABT switches (see 3.4.2.3.13).
o.
Setting for inhibiting transfer on overload (see 3.4.2.3.14).
p.
Indicator test feature (see 3.4.5.2.1).
q.
Special auxiliary switch requirements, if necessary (see 3.4.10).
r.
Type switching mechanism for ABTs greater than 600 A (see 3.4.11).
s.
EMI criteria, if required (see 3.4.18).
t.
Source-to-source impedance for operation (see 3.4.30.4).
u.
Source-to-source leakage current for maintenance (see 3.4.30.5).
v.
Active ground fault detection requirement (see 3.4.37).
w. Special endurance and overload requirements, if required (see 3.4.38).
x.
Special short-circuit withstandability test, if required (see 3.4.39).
y.
Degree of enclosure (see 3.4.41).
z.
Airborne noise limits, if required (see 3.5.9).
aa. Structureborne noise limits, if required (see 3.5.10).
bb. Manufacturer provided written warranty.
6.3 Qualification. With respect to products requiring qualification, awards will be made only for products,
which are, at the time of award of contract, qualified for inclusion in Qualified Products List QPL-17773 whether or
not such products have actually been so listed by that date. The attention of the contractors is called to these
requirements, and manufacturers are urged to arrange to have the products that they propose to offer to the Federal
Government tested for qualification in order that they may be eligible to be awarded contracts or orders for the
products covered by this specification. Information pertaining to qualification of products may be obtained from
Commander, Naval Sea Systems Command, ATTN: SEA 05Q, 1333 Isaac Hull Avenue, SE, Stop 5160,
Washington Navy Yard, DC 20376-5160 or emailed to CommandStandards@navy.mil.
