3 Siemens AG 2010 Overvoltage Protection Devices Lightning arresters, type 1 Overview Lightning arresters type 1 protect low-voltage systems against any overvoltage or high impulse currents that may be triggered by a direct or indirect lightning strike. The protection level is lowered to 1.5 kv by the lightning arrester. The lightning arresters are enclosed and are suitable for installation in the precounter area. All spark gaps are tripped. For this reason, decoupling reactors are no longer required for the installation of overvoltage protection devices. The lightning arresters are tested using a wave-shaped 25 ka to 100 ka lightning impulse current with waveform 10/350 µs. Benefits The rated arrester voltage is a uniform 350 V AC. This increases safety in systems with extended voltage overshoots. All lightning arresters are fitted with a mechanical fault indication, which does not require an extra power supply. This means they can be installed in the precounter area, where electrical plants can be protected particularly effectively. The protective modules are plug-in versions. No dismantling of electrical wires required when replacing the protective modules. When taking insulation measurements, the protective modules are simply removed in order to ensure disconnection from the power supply. All lightning arresters have a remote signaling contact, which signals if the device fails.

5 Siemens AG 2010 Overvoltage Protection Devices Combination surge arresters, type 1 and type 2 Overview Combination surge arresters type 1 and type 2 protect lowvoltage systems against the overvoltages and high currents triggered by direct lightning strikes. They are tested by waveshaped lightning impulse, 25 KA to 100 ka with waveform 10/350 µs. The protection level is lowered to 1.5 kv by the combination surge arresters. A thermal isolating arrester disconnector offers a high degree of protection against overload. All spark gaps are tripped. For this reason, decoupling reactors are no longer required for the installation of overvoltage protection devices. Benefits The rated arrester voltage is a uniform 350 V AC. This increases safety in systems with extended voltage overshoots. All combination surge arresters are fitted with a mechanical fault indication, which does not require an extra power supply. The protective modules are plug-in versions. No dismantling of electrical wires required when replacing the protective modules. When taking insulation measurements, the protective modules are simply removed in order to ensure disconnection from the power supply. The same type 2 overvoltage protective modules are used as for the slim version of the surge arresters (5SD7 42.). This simplifies stock-keeping. All combination surge arresters have a remote signaling contact, which signals if the device fails.

7 Siemens AG 2010 Overvoltage Protection Devices Overview Surge arresters type 2 are used downstream of lightning arresters type 1 in main distribution boards or sub-distribution boards. They protect low-voltage systems against transient overvoltages. The type 2 surge arrester lowers the protection level to 1.4 / 1.5 kv. A remote signaling contact signals whether a protective module has been disconnected from the network by the thermal arrester disconnector or whether it is just not plugged in. All spark gaps are tripped. For this reason, decoupling reactors are no longer required for the installation of overvoltage protection devices. To ensure fault-free operation of photovoltaic systems, it is essential to have standardized protection against lightning and overvoltages. SPDs (5SD ) on the DC side protect the photovoltaic generator and the inverter against overvoltages. The SPDs 5SD and 5SD are especially available for protecting IT systems. Benefits The rated arrester voltage is a uniform 350 V AC. This increases safety in systems with extended voltage overshoots. All type 2 surge arresters are fitted with a mechanical fault indication, which does not require an extra power supply. A thermal isolating arrester installed in each device offers a high degree of protection. In the event of overload, the surge arrester is disconnected from the mains - the plant continues running The protective modules are plug-in versions. No dismantling of electrical wires required when replacing the protective modules. When taking insulation measurements, the protective modules are simply removed in order to ensure disconnection from the power supply. All surge arresters are available with a remote signaling contact, which signals if the device fails.

16 Overvoltage Protection Devices Siemens AG 2010 Surge arresters for measuring and control technology Overview The surge arresters for measuring and control technology are overvoltage protection modules that comprise two parts, a basic element and a plug-in part. Their application area is the protection of signal circuits. The cable shields of basic elements can be either directly or indirectly grounded. The mounting width of the new surge arrester is 1 MW. Through the number of integrated paths, it is possible to protect up to four signal cores or two double cores against overvoltages. Benefits The two-component design offers users maximum maintenance convenience. The basic element is always a fixed integral part of the installation. There are therefore no laborious access problems during repair work, etc. The benefits: - Two-part design comprising plug-in part and basic element - Interruption-free and impedance neutral plugging in and pulling out of the plug-in part - Reverse polarity protection through mechanical encoding - An electric surge voltage resistant connection is made automatically when it is snapped onto the standard mounting rail no laborious wiring of ground. The arrangement of suppressor diodes between signal cores achieves a fine protection in connection with a fast response. The low-limiting coupling of the suppressor diodes to the signal cores supports fast data transmission rates. The use of gas-filled surge arresters ensures a high discharge capacity.
