Type 1 surge protection (lightning current arrester) constitutes the first stage in the protection concept. It can discharge very high energies, e.g., caused by a lightning strike, to ground. Type 1 surge protective devices (SPDs) are usually installed in the feed-in or main distribution system. For additional energies with lower surge voltage pulses, type 1+2 combined lightning current and surge arresters are required.

FLT-MB type 1+2+3 combined lightning current and surge arresters provide maximum power in a minimum amount of space
The FLT-MB type 1+2+3 lightning current and surge arresters are based on our triggered multi-carbon spark gap technology. The portfolio includes circuit versions for a discharge capacity of 12.5 kA and 25 kA.
The FLT-MB devices with 25 kA protect against lightning currents of lightning protection level I/II. The FLT-MB with 12.5kA discharge capacity satisfies the requirements for installations in lightning protection level III/IV.
What’s special about the type 1+2+3 combined lightning current and surge arresters is that they are capable of handling multiple lightning pulses in an overall width of just 72 mm. The space-saving design of just four HP results in easy installation and flexible installation options in the control cabinet.
Type 1+2 combined lightning current and surge arrester – FLT-SEC-P-T1-3S-350
Every type 1 lightning current arrester fulfills the high requirements in terms of discharge capacity. At the same time, it is also a type 2 surge protective device (SPD). The fact that a type 1 lightning current arrester satisfies test class II is redundant information and does not constitute an additional qualification. Therefore, such protective devices are called combined lightning current and surge arresters (SPD type 1+2). A combined lightning current and surge arrester is a protective device that fulfills both test classes.
Type 1+2 special combined lightning current and surge arrester – FLT-SEC-T1+T2-3S-350
The type 1+2 special combined lightning current and surge arrester differs fundamentally from the type 1+2 version. This is because the type 1+2 special combined lightning current and surge arrester contains two independent protective devices that are connected in parallel in a very small space. The voltage-switching spark gap (SPD type 1+2) works ideally in combination with a voltage-limiting varistor (SPD type 2). In this combination, two autonomous protective devices in one compact block ensure optimum response behavior, optimal system protection, and a long service life for the components.
FLT-SEC-H-T1-1C-264/25-FM – Type 1+2 combined lightning current and surge arresters with integrated backup fuse
The FLT-SEC-HYBRID ensures maximum operational safety in industrial systems directly at the feed-in. The spark gap without line follow current and integrated surge-proof backup fuse enable quick, safe installation without a separate backup fuse. This means that up to 80% less space is required compared to conventional installations with backup fuses. This ensures that the system remains reliably protected even under high loads.
Type 1+2+3 combined lightning current and surge arrester for 40 mm busbar systems
The FLASHTRAB FLT-SEC-ZP2 is the first choice for protecting residential buildings and functional buildings with external lightning protection or a overhead line supply. The device is characterized by its narrow width, which saves space in the mains-side wiring space of the meter box.
Naturally, to take advantage of the simple installation, the FLT-SEC-ZP2 can also be used in buildings without external lightning protection or overhead lines.
• Fast and error-free installation with direct mounting on the 40 mm rail system
• Its flexible overall width of 27 mm means it fits in every distribution board
• Fulfills all requirements of the VDE-AR-N 4100 standard
