  • Full protection status control with optional pre-warning function
  • Intelligent locking mechanisms ensure reliable operation even under harsh environmental conditions

Lightning and surge protection VPU I

Class I SPDs for lightning protection and equipotential bonding in energy grids.

Lightning and surge protection VPU I
Vos avantages
  • Tested by IEC/EN 61643-11 up to Iimp 25 kA (10/350µs ) lightning pulse
  • Supports all common energy grids like TNC, TNCS, TNS and TT for 230/400 V or 400/690 V systems
  • Combined varistor/spark gap technology for leakage current free products
  • Space savings of 50 % due to reduced width

VARITECTOR PU ZPA for mounting on 40 mm busbars Product innovation

Class I+II SPDs with 7,5 kA and 12,5 kA for bus bar system

According to the specifications of DIN VDE 0100-443 and -534, surge protection is an obligatory component of every energy supply – especially in building infrastructures. Surge protection, therefore, has to be provided for commercial and private buildings. The series connection of varistor and spark gap guarantees leakage current free protection between the line conductors as well as for the protective earthing conductor.

VARITECTOR PU ZPA for mounting on 40 mm busbars
Vos avantages
  • Tool-free installation in 230/400 V TNC, TNS or TT-Systems
  • Complete status control
  • Innovative, additional voltage tap
  • Versions with remote signalling contact
  • Space-saving design, only 47 mm
  • Fuseless operation up to 315 A backup fuse

Due to its width of only 47 mm, the ZPA module can also be combined with 2 SLS switches. All requirements of the utility companies are met. Tool-free installation increases safety and efficiency.

Our compact Type I/II surge protection modules for 3-phase power supply networks are ideally suited for use in building infrastructures and can be mounted on 40 mm busbars. They enable direct connection of the busbar with a separate PE connection and combine Type I and Type II arresters for lightning and surge protection in a single product on only 47 mm. The optional additional voltage tap and the remote monitoring output increase the added value for many applications.

Product variants with an impulse discharge current of 7.5 and 12.5 kA allow an application oriented selection of products.

An optional additional voltage tap with PUSH IN connection allows devices such as a modem to connect directly, without expanding the 40 mm busbar system.

VPU SERIES: long-lasting, safe, and future-oriented

Our VPU I, II, and III surge protection devices effectively reduce the interference coupling that occurs with transient overvoltages, so that it remains well below the limits specified in EN 60664-3 (DIN VDE 0110-3). The entire system is exposed to fewer malfunctions. The arresters are coordinated by technical means.

Vos avantages

  • No decoupling between Types I, II, and III required
  • Tested according to IEC 61643-11 and DIN EN 61643-11
