PRODUCT DESCRIPTION:

POWERTEC 25, 60 (R) with a low protection level is a selective, twolevel T1 + T2 (B+C) surge arrester, which combines protection classes I+II in a single device. This means no decoupling elements are required for cable lengths under 10 m. Using hermetically seale spark gaps filled with inert gas means that the requirement of a high discharge capacity is fulfilled while maintaining functional stability. The first level (non-linear resistor type arrester) discharges impact currents (up to 4kA) without causing any mains follow-currents. When a pre-defined impact current (up to 4 kA) has been exceeded, the second level (the hermetically sealed spark gap filled with inert gas) engages for the less common discharge of highenergy transients up to 25 kA / 60 kA (10/350 μs) which may arise during close-up or direct lightning strikes. As an option, a potentialfree relay contact (R) with terminal is included in the enclosure- to aid signalising.

V-wiring can be easily installed using the unlabelled terminal (the one not connected with the L/N terminal in the device) using the optional 2-pole comb-type rail.

RANGE OF APPLICATION

SG50 used in combination with COMBTEC VV, VS, G100 in combination with PROTEC, POWERTEC in 3 + 1 switching operation is used to protect against direct lightning strikes in external overhead lines or external lightning arrester in the TT system. See graphic for application.

PRODUCT DESCRIPTION:

SG 50, G 100 are 1-pole N/PE lightning arresters with protection class I+II+III (B+C+D) for protection against partial lightning currents from entering electrical installations. The device is used for equipotential bonding of lightning protection in the 400/230 VAC TT system, as a N/PE conductor with 3 + 1 switching operation.

It is able to deflect lightning currents up to 50 kA / 100 kA (10/350 μs) with a charge of 50 As, and has a low protection level, Up < 1,5 kV. The use of a hermetically-sealed high-performance spark-gap filled with inert gas makes use of a dangerous blow-out opening superfluous.

INSTALLATION- AND OPERATING NOTES:

A gap need no longer be enforced between neighbouring cables and components to prevent arcing faults. Given that this arrester is required to deflect high lightning currents, we recommend the use of single-wire Cu conductors upwards of 16 mm2. The entire length of the connectiosn must not exceed0.5 m. If this cannot be ensured, install the PE conductor with an extra terminal V-formed where possible.

CAUTION:

The SG 50, G 100 must only be installed by specialist electricians. All valid norms must be observed during mounting and installation. This device must only be used as a N/PE aggregate-lightning arrester in the 3+1 switching operation, appropriate to the lightning protection class.

FAULT DETECTION

When required, this arrester can also be tested using an insulation meter. When Risol 0.5 to 1 M 1 , the arrester must be replaced at the next opportunity, when Risol < 0.5 M1 it must be replaced immediately.
