Surge protection with greater coordination:
OBO Coordinated-LightningController MCD 50-B and MCD 125-B/NPE
When combined with surge arresters connected in series immediately downstream, the new OBO lightning arresters MCD 50-B and MCD 125-B/NPE ensure a coordinated response, without the need for additional decoupling elements. The fundamental advantages of the innovative multi-carbon technology of OBO LightningControllers are fully preserved. The low protection level (≤ 1.3 kV) makes it unnecessary to install decoupling inductances or to provide additional lengths of conductor between lightning arresters (requirement class B) and surge arresters (requirement class C). This results in a space saving on installation of up to 45 per cent, a great advantage where compact EMC concepts are concerned. In addition, the separate NPE spark gap at the surge arrester (requirement class C) with compact TT and TN-S systems can be omitted.
Preferred fields of application for the new OBO devices are compact surge protection concepts in separate housings and the installation of arresters of requirement classes B and C in a distribution board. Typical applications: compact mobile phone installations.
