ZGGF20-260B(3+1)Modular Power Supply SPD is made by special nonmetal material, adopting design of laminate discharging technology & omniseal, standard installation 35mm lead rail. It is provided with features like large impulse discharge current capacity, low measured limiting voltage, without arc escaping nor leakage current, strong ability of follow current interrupt, convenient connection. It is widely used in 1st class power supply for lightning protection, applying to different power grid systems (TN, TT and IT), so as to protect devices from direct stoke or lightning induction.
Features 1 High impulse current capacity, low residual voltage. 2 Omniseal design, no arc escaping, nor leakage current, strong ability of follow current interrupt. 3 With Failure Indication.
Temperature: -33~70centidegree Relative Humidity: 10%~85%(25centidegree) Sea Level Elevation: Less than 3000m
External structure Outline Dimension: 90mmx90mmx68mm (Width x Height x Depth) Installation Dimension: 35mm DIN Rail installation Flame retardant grade: UL94 VO Protection grade: IP20
Executive standard IEC 61643-1: 2005 UL 1449: 2010 EN61643-11: +A11: 2007 2002/95/EC2005/618/EC
Installation, operation and maintenance
The Modular Power Supply SPD can only be installed by trained professionals, check the SPD before installation, any damage can not be used.
The SPD should be installed after the power supply line fuse or circuit breaker.
To wire in Figure3 according to the mark of the SPD, cable cross-sectional area is no less than 25mm² , the insulated copper wire can resist voltage no less than 500V AC, the length of wire stripping is 13-15mm. The cable should be as short as possible and no more than 0.5m. Reliable ground and meet the requirements of relevant standards.
Operation and Maintenance
1. After the failure of the ZGGF20-260B (1+1) Module SPD, the green indicator on the panel is off, and the protector should be replaced immediately. 2. In normal use, the grounding system of this lightning box should be checked, especially in the thunder season to always maintain a stable ground state. Otherwise, the protective effect of the lightning protection box will be influenced varying degrees, when ground wire opened, the lighting protection box will lose the protective effect.
Warning: L N can not be reversed. To reduce the risk of electric shock, only use indoor. Maintenance required cutting down the power.
Package Transport and Storage
Product packaging with moisture-proof, anti-vibration, A packaged box with one SPD, enclose a instruction, and packaging materials can be re-use.
Products in transit should be canopy, should not be a severe vibration and impact.
Storage temperature-40~80centidegree, the relative humidity is less than 85%. The warehouse needs ventilation, ground dry, non-corrosive gases. The product needs to be re-tested when the storage period excel one year, and can be use after passing.
