Surge protector use
Surge is also called surge, as the name implies, it is an instantaneous overvoltage that exceeds the normal operating voltage. Essentially, a surge is a violent pulse that occurs in just a few millionths of a second and can be caused by: heavy equipment, short circuits, power switching, or large engines. Products containing surge blocking devices can effectively absorb large bursts of energy to protect connected equipment from damage.
Surge protector, also known as lightning arrester, is an electronic device that provides safety protection for various electronic equipment, instrumentation, and communication lines. When a surge current or voltage is suddenly generated in an electrical circuit or communication line due to external interference, the surge protector can conduct and shun the current in a very short period of time, thereby avoiding damage to other equipment in the circuit by the surge.
SZ-NPE series surge protector is suitable for TT， TN-S， and other power supply systems of 50/60HZ， 230/400V and below.It is used between neutral line(N) and ground line(PE) to protect the surge caused by indirect lightning and direct lightning or other instantaneous overvoltage.Products comply with GB 18802.1, GB50057andIEC 61643-1 standards.
SZ-NPE by gas discharge tube or air as the main components of discharge gap, in general, went into a state of high resistance between electrodes, when power grid because of thunder and lightning directly or indirectly other transient overvoltage surge, electrodes in a nanosecond time conduction, will surge into the earth, and to protect the equipment on the power grid, when the surge through the NPE disappear, TheN PEis restored to the high resistance state without affecting the normal operation of the power grid
And SZ-SPD series surge protector can be combined into the following solutions：1P+NPE, 3P+NPE and other SPD combination to improve the anti-surge performance.With common mode(MC) and differential mode(MD) protection mode.Adopt 35mm standard guiderail installation, the zero line is connected with 2.5-35mmwire, the grounding wire is connected with more than 6mm double-color multi-strand copper wire, the length is not more than 500mm.
Usually installed in residential distribution boxes, computer centers, information equipment, electronic equipment and control equipment in front of the nearest socket box.
