Assemble and defend
Series of products applies to equipment fore-end
The protection implement applies to interior installation , installation adds water-proof facilities of dress outside be obliged to
Be obliged to solid and reliable electricity of all connection connection, lightning protection ground connection responds to a magic figure
Agree well with the lightning protection standard request. Ground connection achieves to the full short but straight
May demand to be custom-made according to the customer
Applicable scope
The OBVU9 series electricity wells up the protector (to hereafter refer to as SPD) to be suitable in exchanging 50/60Hz, the voltage 220V single-phase power supply system, uses the electric appliance to the electrical appliances and the similar place, appears the question indirect thunder and lightning and the direct thunder and lightning influence or other instantaneous overvoltage when the line carries on the load two levels of protections.
SPD conforms to GB18802.1-2002/IEC61643-1.1998å’ŒYD/T1235.1-2002.
Installs and uses
1, installs in LPZ2 or the LPZ3 area intersection point, with enters the terminal SPD according to the cascade way arrangement, the connection copper nature wire is 1~4mm2, its length is not bigger than 500mm.
2nd, SPD each must establish the protection - use fuse or the small circuit breaker extremely.
The contour and installs the size
