AC Power Supply Surge Protective Device
(Class II 40kA / Type 2)
1. Product Introduction
DK-40 power series modular surge protective device (SPD) is applied to low-voltage distribution
system. As a lightning surge protection device for various kinds of equipment, it is connected in parallel
type. With beautiful appearance, easy installation and wiring, simple maintenance, module series SPD can
long-term stably work under the circumstance of severe weather.
This power series modular surge protective device has the functional characteristics as below: Large
flow rate, low residual voltage; Built-in over-current, overheating, disconnection device; Remote
defect indication, remote communication alarm interface; Standard 35mm electric rail installation

4. Application Scope
It can be installed in the low voltage power distribution cabinet/box of buildings, to protect all kinds of power equipment in the single (three) phase power distribution system between LPZ1 and LPZ2.
5. Installation Instruction
1) Power series modular surge protective device can be installed in the front end of the protected
equipment. Generally, it is installed in the power distribution cabinet/box, or the the power switch
entrance. It is with the power grid in parallel connection type (Please pay attention to the phase line, null
line and the GND).
2) When installation, please use Kevin Connection Mode as soon as possible, that is, shuck off the
insulating layer from the middle of power distribution power line, then put the power line in the relative
connection terminal and tighten the screw.
3) When using the general parallel connection mode, the conductor sectional area of power SPD much
be more than 4mm2 (the specific conductor size, please choose according to the size of distribution power
line). Grounding wire should be 6~25 mm2 copper conductor. It is better that the length of connecting line
is less than 0.5 meter, and the remote monitoring terminal is less than 1.5 mm2 copper conductor.
4) The sectional area of grounding connection line should be greater than the phase line and null line,
and the distance from grounding wire to assembly grounding unit is less than 1 meter, Resistance to the
Ground≤10Ω.

7. Maintenance
There is an indication window in the SPD. When the SPD is damaged, the indication window turns red.
Under the circumstance, please remove the damaged modular to replace a new one.
