Power supply systems in accordance with North American standards differ significantly from those in accordance with IEC standards. Apart from the supply system configurations and voltages, the technical and normative requirements also differ. Surge protective devices in accordance with IEC do not comply with these requirements. For this reason, specific SPDs are available for North American supply systems. These comply with the North American standards in accordance with UL and CSA.

As part of the Safe Protection Plus family, VAL-US-SPP features surge protective devices for all power supply systems in North America in accordance with the NEMA standard. These UL.-listed SPDs provide robust protection with innovative installation and safety features and are easy to integrate.
Surge protection for North American supply systems – VAL-US
VALVETRAB US-SPP devices are pluggable surge protective devices for installations and systems in accordance with the NEMA standard. The products in the VAL-US-SPP family are UL Listed, making them ideal for use in the American market. The VAL-US-SPP series includes a wide range of circuit configurations. There are corresponding product versions for conventional supply systems such as 120/240 V Split-phase and 277/480 V Wye, but also for special supply network types such as 120/208/240 V High-Leg Delta and Corner-grounded Delta.
Surge protection is mandatory in the USA for safety operating data systems and critical operating data systems. The National Fire Protection Association (NFPA) 79: Electrical Standard for Industrial Machinery, a supplementary document of the National Electrical Code (NEC), describes requirements for the protection of operators, equipment, equipment, and ongoing operations. In order to meet these requirements, UL-listed surge protection has been stipulated since the 2018 edition of NFPA 79. Using the VAL-US-SPP ensures that you meet these requirements and are on the safe side.
