BY1-D Surge Protective Device

Product Description

Installation
1 It adopts 35 mm DIN rail
2 It is linked by 2.5 -- 35 mm? copper wire, and there are 2 wiring methods:
A) From power switch to protective device, then from protective device again to the load end. This way suits to the distribution case which load current is under 100 A. The wire section should be selected by the load current.
B) From the power switch to protective device, also from the power switch to load end. This way suits to the distribution case which load current is over 100 A. The wire section should not be selected by the load current, but it can't be longer than 500 mm.
3 The earth cable should choose the double color wire which is over 4 mm? but not longer than 500 mm.
4 In order to guarantee electrical network's normal operating after protective device losing efficiency, the protective device which linked to the phase line must be connected a 32A fuse box.
5 Figure 5 is the appearance and installation dimension about the device.
