Phoenix Contact introduces new surge protection devices for 1,500 volts
article originally published in www.sunwindenergy.com, on June 26th, 2015
Large photovoltaic systems are increasingly using a higher operating voltage of 1,500 V, which makes transmitting the electricity to the inverter more cost-effective. Phoenix Contact has now introduced the new VAL-MB product range of type 1/2 lightning / surge arresters for this application area. The devices in this product range are suitable for the higher generator voltage.
The manufacturer emphasises that the devices are specifically designed to fulfil the requirements of DC applications and are certified by the Dutch KEMA (DNV GL). The protection devices feature longer cable insertion funnels and higher protective shafts for the screws to improve protection against arcing. The product range includes type 1/2 lightning/surge arresters as well as simple type 2 surge protection devices for generator voltages of 600, 1,000 and 1,500 V DC. Phoenix Contact supplies the devices with or without remote indication contact. The manufacturer specifies a short-circuit rating of 2000 A for this range of surge arresters, and they can be used at altitudes of up to 6,000 metres above sea level.
