High demands are placed on the availability of electrical systems. With Safe Protection Plus, Phoenix Contact is already setting the surge protection standards of the future, today. The VAL-SPP devices combine forward-thinking installation and safety features that ensure the high availability of your system.

Surge protection goes a step further

The advantages of the VAL-SPP product family SPP stands for Safe Protection Plus and that means:

  • Easy and safe installation with forward-thinking handling and safety features 
  • Reliable system protection with maximum performance and endurance
  • Can be used in a wide range of applications due to the optimized design and broad portfolio
  • Simple planning due to comprehensive digital data and selectors

VAL-SPP devices 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 VAL-SPP product family therefore offers forward-thinking advantages that already meet the standards of the future, today.

The VAL-SPP product family provides 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.

VAL-SPP surge protection in harsh environments

VAL-SPP covers applications for AC and PV with various different nominal voltages. Versions for grids with strong voltage fluctuations extend the portfolio. The robust design enables installation in harsh environments and at altitudes up to 5000 m. The option of use without a backup fuse up to 315 A enables space-saving and cost-effective installation.

Modular remote signaling
For many product versions, the Safe Protection Plus product family offers modular remote signaling that can be quickly and easily plugged into the corresponding base element. The remote signaling has reinforced insulation for the main circuit, which further increases electrical safety.
Mechanical status indicator
Each plug has a mechanical status indicator. This enables the identification of overloaded protective plugs directly on site.
Pluggable surge protection
The protection modules can be plugged in separately for each path. Overloaded plugs can thus be replaced quickly and inexpensively.
Reduced tightening torque
The tightening torque has been reduced to 3 Nm. The low tightening torque makes it easier to install the protective devices correctly.
New disconnection
Due to high-performance disconnection, surge protection in the event of an overload and fault is even faster and more reliable.
Miswiring and touch protection
The products are equipped with miswiring and touch protection. This prevents incorrect insertion under the clamping pockets. Touch protection ensures greater safety during operation. Current-carrying parts can no longer be touched once the cables have been connected.
Bi-Connect connection
The products for AC applications are equipped with Bi-Connect connections. This means that you can easily bridge the surge protection to other components, such as miniature circuit breakers.

Due to high-performance disconnection, surge protection in the event of an overload and fault is even faster and more reliable.
Pluggable surge protection
The protection modules can be plugged in separately for each path. Overloaded plugs can thus be replaced quickly and inexpensively.
Remote signaling
Depending on the requirements, surge protective devices for photovoltaic applications are available with or without floating remote indication contact.
Extended screw shafts
The extended screw shafts optimize the air clearances and creepage distances and therefore offer greater safety even in the case of higher DC voltages.
Extended insertion funnels
The insertion funnels are also extended in order to achieve better air clearances and creepage distances. At the same time, the extended insertion shafts provide touch protection and miswiring protection.
Mechanical status indicator
Each plug has a mechanical status indicator. This enables the identification of overloaded protective plugs directly on site.
Type 1 and type 2
The protective devices are designed in a 2+V circuit. They are available both as type 1 lightning current arresters for 1000 V DC or as type 2 surge protection for 600 V DC, 1000 V DC, or 1500 V DC.
