This fuze has a spring loaded striker with a chemical release.
It is produced in two sizes; the larger is 12.7 centimeters (5.0 inches) long and 3.4 centimeters (1.3 inches) in diameter, and the smaller is 5.0 centimeters (1.9 inches) long and 1.5 centimeters (6.0 inches) in diameter.
Both fuzes are primarily used in mines or charges as a safety delay element in an electric detonating circuit.
The smaller fuze has a delay of 10 minutes to four hours while the larger has a delay up to four months.
The delay is affected slightly by temperature; a low temperature increases the delay while high temperatures decrease it.
Electrolysis begins when the fuze is connected into an electric detonating circuit.
After a time lapse, the striker retaining wire is eroded to the point where it breaks, releasing the striker, which closes the cicuit and fires the detonator.
The EKhP is enclosed in a cylindrical tar impregnatedcardboard container.
