ATFILTER 32 AC Single phase Surge Protector
ATFILTER 32 device has been conceived with the purpose of providing a highly efficient protection to electronic equipments against overvoltages and high frequency disturbances.
This is achieved by mean of placing gas discharge tubes and supressor diodes beside a high quality low-pass frequency filter, what implies a full protection
against pulses of high amplitude and/or frequency.
Every electric disturbance above 100Hz will be attenuated. Tight protection according to scaled protection recommended in Low Voltage Regulation (RBT2002 ITC23). Class II and III according IEC61643-1, EN61643-11 standards. Suitable for Categorie I, II, III and IV equipment according to RBT2002.
There are several models depending on the nominal current of the line to be protected (IN ). The proper working of the ATFILTER 32 equipments has been certified by official independent laboratories , verifying the proper coordination between SPDs.
INSTALLATION ATFILTER
ATFILTER 32 devices are to be installed in series with the power supply line, that is, cutting the line and connecting the obtained cable ends to the input and output connectors. Please pay attention to these connections since if terminals are wrongly wired, a short circuit may happen.On the other hand, it’s of capital importance a right wiring of input/output terminals. If not, protector components won’t act properly. Linking the earth terminal to ground is a must. The power should be disconnected during the installation of the SPD. The protector is ready to be fitted on the DIN rail of the distribution board, the closest to the equipment to be protected against overvoltages and screened against electromagnetic noise.
Earth connection is a must. Earthing in all the installation must be bonded either directly or by a spark gap and resistance should be lower than 10 Ω. If the indications of this datasheet are not fulfilled during the use or installation of the SPDs, the protection assured by this device could be endangered.
