Serial protection circuit, very low residual voltage, good protection performance
Adopted special thermal disconnect technology, thus stands to prevent from fire risk.
Adopted multiple automatic current equalizing technology for withstanding multiple lightning strikes, thus shall be the first choice particularly for areas liable to lightning
SPD¡¯s status indicated by double colored LED, clearly and directly.
Fault alarm functions (by alarm interface) so as to facilitate remote monitoring.
Convenient installation and easy maintenance.
Applied fine techniques, thus is capable of lasting long time under severe conditions.
JD065K385C30DH3-A1 type SPD for single-phase power supply system is used to
protect 220V A.C. power supply system and electrical equipment against damages caused by lightning current and surges, etc.

Isolation between separate circuits
The remote alarm interface is isolated from the main circuit by reinforced insulation according to EN 60950-1:2001 and with dielectric withstand voltage 3000Vrms.
1¡¢SPD can be installed in power distribute box and so on and mounted by screw. 2¡¢Wiring of SPD is as shown in Chart1.& 2. the input wires to ¡°Lin¡±, ¡°Nin¡± terminals, the output wires to¡°Lout¡±,¡°Nout¡± terminals; lead out earth wires from ground terminal to the earth bus for lightning protection system. Please refer to diag.2. 3¡¢In case of remote alarm, alarm leads are connected to alarm terminals then be plugged into alarm interface. Please refer to Chart3 .
NOTICE
1¡¢Cross section of connected conductor shall meet the technical requirements. 2¡¢No special maintenance needed except for periodic inspection for looseness of connections and normality of indication. 3¡¢Indicator shines green, the mean is the SPD normal, indicator shines red, the mean is SPD fault and should be replaced. 4¡¢When an alarm is given, there may be a damaged component (if indication LED shines red), and the SPD should be replaced.
