GERMAN FUZES
(28) A – ELECTRICAL IMPACT FUZE
DATA:
Bombs Used in: H.E. bombs, as for (25) B.
Color: Drak grey; yellow paint on shoulder.
Material: Aluminum.
Possible Actions: (a) Instantaneous. (b) 0.15-sec. delay. (c) 14-sec. delay.
Principal Markings: El.A.Z. (28) A.
Secondary Markings:
AA 1940 cpp 1942.
AB 1940 Rh.S. 1939.
FC 1940.
cpp 1941 Rh.S. 1940.

DESCRIPTION: The circuit of this fuze is similar to that of the (39) althrough the values of the components differ. Three firing circuits are incorporated.

Safety switching is accomplished by depression of either plunger, which switches off the opposite arming circuits. (See fig. 160.)

ARMING TIMES:

Level Flight
(150 v.)

Diving Flight
(240 v.)
Instantaneous: 1.6 - 2.8 sec. 1.0 - 1,5 sec.
0.15-sec. delay: 2.1 - 3.3 sec. 1.4 - 2.2 sec.
15 sec. delay: 0.7 - 1.3 sec. 0.3 - 0.7 sec.
REMARKS: 1. Type 2 construction.
