Meba lightning arresters MBD1-D20
Product Description
Meba lightning arresters MBD1-D20 is suitably used in the IT, TT, TN-C, TN-S, TN-C-S and etc power supply system of AC 50/60Hz, rated voltage up to 380V, to protect from direct and indirect lightning impulse and other transient over voltage. As per the conditions of IEC61643-1:1998-02 standard, Class III surge protective device, it is category D surge protective device.SPD has two protection modes: MC and MD SPD is in compliance with GB18802.1/IEC61643-1 standardsMeba lightning arresters MBD1-D20
Operation Elements
SPD as only one side of terminals, able to prevent from being electric touching, indoor fixedly mounted, limiting voltage. SPD has built-in disconnector, when SPD is invalid due to overheating or breakdown, the disconnector can automatically separate SPD from the network, meanwhile send an indication signal. The visible window show white color in normal service, if to be separated from network, it will show red color. 1P+N, 2P +N, 3P+N SPD consist of 1P 2P 3P SPD and NPE neutral and earthing protection modules, used in the power supply system of TN-S , TN-C-S and etc.
Installation
– To be mounted between LPZ1 or LPZ2 zone and LPZ3 zone, adopts 35mm standard mounting rail. The cross sectional area of multi-strand s oft copper conductor : 2.5 – 35 mm2.
– Every pole of MBD shall be protected by fuse or mini circuit breaker.
– It is mounted in distribution boxes of living house, computer center, communication equipment, electronic equipment and control equipment or nearest socket box.
