220V 380V Power Surge Protection Device Customized Color
Product Description
Power surge protector, also known as the power supply lightning protection, for AC 50/60HZ, rated voltage 220V/380V power supply system, the impact of indirect lightning and direct lightning or other transient overvoltage surge protection, applicable to family homes, the third sector and industrial areas of surge protection requirements, with relative phase, relative to the ground, relative to the center line, the center line to the ground and its combination of protection modes.
Application areas
Power surge protector for AC 50/60Hz, rated operating voltage
220V/380V TT, TN-S, TN-C, IT and other power supply systems and
low-voltage power and control systems in factories, the impact of
indirect lightning and direct lightning or other transient
overvoltage surge protection, mainly for residential, tertiary
industries and industrial and mining enterprises and other areas of
surge protection requirements
Difference with lightning arrester
Lightning arrester
1, lightning arrester has a number of voltage levels, from 0.38KV
low voltage to 500KV ultra-high voltage are available, while the
surge protector is generally only low-voltage products;.
2, lightning arrester more than installed in the primary system to
prevent the direct intrusion of lightning waves, and surge
protectors are mostly installed in the secondary system, is in the
lightning arrester to eliminate the direct intrusion of lightning
waves, or lightning arrester does not eliminate the lightning waves
clean when the supplementary measures;.
3, lightning arrester lightning arrester is to protect electrical
equipment, while the surge protector is mostly for the protection
of electronic instruments or meters;.
4, lightning arrester as a result of connecting to the electrical
primary system, to have sufficient external insulation performance,
the appearance of the size is relatively large, while the surge
protector as a result of connecting to the low voltage, the size of
the production can be very small.
Surge protector
1, frequency control cabinet must be added
2, the use of vacuum circuit breakers must be added to the control
cabinet
3, the power supply system into the line switch must be added
4, other control cabinets can not be added, of course, if the
budget space for insurance purposes can be added
Surge protector is divided into two categories: motor protection
type, power station protection type in the selection must pay
attention to [3] .
