With Safe Protection Plus (SPP), Phoenix Contact is setting new standards in lightning and surge protection. The SPP product family combines top performance with a compact, pluggable design to ensure maximum system availability and optimum protection. With the powerful type 1 lightning current arresters and the versatile type 2 surge protective devices, the family is now complete.
The surge protective devices in the Safe Protection Plus product family provide maximum performance and endurance to deliver reliable protection. Reinforced insulation also ensures additional user and system safety. The direct response behavior protects the backup fuse and installation. Rapid disconnection guarantees a high level of operational safety.
With its wear-free, triggered multi-carbon spark gap, FLT-SPP features very fast response behavior and a low residual voltage. Compared with varistor-based (MOV) lightning current arresters, the load on the end device is significantly reduced, which greatly improves the protective effect for the whole system.
The VAL-SPP surge protective devices feature direct response behavior, effectively protecting the backup fuse and installation. Downstream components are reliably protected against residual surge voltages. The rapid disconnection ensures a high level of operational safety in the event of an overload.
The products in the SPP family are characterized by their simplicity and safety. They boast innovative features such as miswiring and touch protection, plus a reduced tightening torque of just 3 Nm. The SPP product family therefore offers forward-thinking advantages that already meet the standards of the future, today.
The robust protective devices with an overall width of 17.5 mm per position are suitable for demanding environments and allow space-saving installation without a backup fuse up to 315 A and at altitudes up to 5,000 m. Thanks to the triggered multi-carbon spark gap, the FLASHTRAB SPP combined lightning current and surge arresters are able to control multiple pulses and are ideal for lightning-intensive regions and applications in exposed locations, such as wind power and telecommunications. VALVETRAB SPP reliably protects AC and solar applications in various voltage and circuit versions. With the products in the Safe Protection Plus family, you’re sure to find the right surge protection for almost any application.
Comprehensive digital data for ECAD systems makes it easier for you to plan your system. Our online selection guide enables you to quickly and easily find the right product for your application. With the modular accessories, additional functions can also be integrated easily at a later time.
FLT-SPP... combined lightning current and surge arresters with triggered multi-carbon spark gap
The FLT-SPP and FLT-MB lightning current and surge arresters use the triggered multi-carbon spark gap. This technology is particularly powerful. Its multi-pulse capability means that even extremely high and closely spaced lightning pulses are handled reliably. The spark gap operates with no line follow current. Short-circuit currents after the discharge process are prevented, thus maintaining system availability. Thanks to low voltage protection levels and a low residual voltage curve, the load on downstream devices is significantly reduced, which offers noticeably better protection, especially compared to varistor-based surge protective devices. In addition to the requirements for type 1 lightning current arresters, they also meet the requirements for type 2 and 3 surge protective devices.
VAL-SPP surge protection for three-phase power supply systems with separate N and PE conductor
VALVETRAB SPP offers an extensive portfolio of type 2 surge protective devices from the Safe Protection Plus product family. The protective devices are available in different circuit and voltage versions. The portfolio ranges from single-channel versions through to ready-to-install solutions for four- and five-conductor systems.
Further information on the products can be found in the linked product list. The respective product detail pages provide technical data, 3D models, installation notes, and much more.
With the VAL-US-SPP products, Phoenix Contact also offers the described installation and safety features for surge protection for North American supply networks. In addition to the different supply voltages, circuit versions such as split-phase, wye, or delta are available in these networks. The VAL-US-SPP items are Open Type UL Listed. This means that they can be integrated into new and existing systems without further testing.
