              Voltage Limiting level B SPD

 

Voltage limiting SPD is usually used in the LPZ1 and LPZ2 zone.It can eliminate The residual voltage on the grid to

 the utmost extent and conduct the 8/20μs analogy lightning impulse current.Level B SPD is generally used to prevent

 the inference to the low voltage.It has Fault detection and remote alarm functions.we can provide the "3+0","4+0"

 and "3+1"protection type according to different power supply system.

 

The indicator switches from red to green when this system malfunctions.

Installation and Maintenance

1.DIN 35MM standard rail installation

2.The product adopt the flame retardant ABS housing,fix the products,connect the power lines and ground lines by 

   the drawing,examine and power up.

3.Grounding is very important to the normal work of SPD.the ground contact area is no less than 25 mm2 and as 

   short as possible.

4.the products don't need special maintenance while it is on position for a long time .So we should assign some 

   people to examine regularly.Especially in The thunderstorm season.Once stuck,check it Immediately.

5.The product is equipped with a fault indicator.when working correctly,the indicator shows green,When this system

    malfunctions,it shows red.

6.The internal components is with alternating current,be careful when the system is working.
