Space-saving terminal blocks
December 2013
Electrical Power & Protection
DEHN’s DEHNconnect SD2 surge arresters are space-saving terminal blocks with a width of 6 mm. Featuring integrated surge protection, they have a modular disconnection function that allows the user to interrupt the signal circuit for maintenance work. An integrated module ejector disconnects the signal circuit from terminal equipment. The disconnection module does not have to be removed, but remains in a parked position in the module slot.
The two-pole surge arresters are designed for signal interfaces of data and information technology systems and for installation in conformity with the lightning protection zone concept at the boundaries from 0B to 2 and higher. Fast and safe conductor connection is achieved thanks to the spring-loaded connection system. The devices have a maximum impulse current carrying capability up to 20 kA (8/20 µs).
Different types of arresters are available and protect two single lines sharing a common reference potential (DCO SD2 ME …) or an unearthed pair (DCO SD MD …). The ATEX and IECEx approved DCO SD2 MD EX 24 arrester can be used for intrinsically safe measuring circuits and bus systems. They are ideal for use in industrial environments at information technology signal interfaces of automation, measuring, control and bus systems.
