Industrial plants and building infrastructures are becoming increasingly complex. This makes them more sensitive to surge damage. In addition, digitalisation is increasing the number of connections and data streams that must not be interrupted. Reliable lightning and surge protection ensures system availability, protects against data loss, and increases added value.

Weidmüller has had standard-compliant lightning and surge protection products in its range for many years and develops customised surge protection solutions with maximum reliability. The proven surge protection devices of the VARITECTOR series are available for power systems, I&C components, and data interfaces.

Surge protection for energy systems

Protects investments. Cares about your expansion.

With our VARITECTOR series we offer you surge protection devices for power distribution systems, electronic devices, and the entire measurement, control, and regulation technology. In addition, there are special protection elements for signal circuits, data interfaces, or telephone systems. The portfolio is supplemented with powerful lightning and surge protection solutions for PV and wind energy systems, transport infrastructure, and the process industry.

Surge protection for energy systems
Your advantages
  • The arresters are tested according to product standard IEC/DIN EN 61643-11 and UL 1449
  • The arresters can be installed in systems according to IEC/DIN 61643-12, IEC 62305-4
  • Fuseless operation up to 315 A backup fuse
  • An integrated locking clip secures the pluggable arrester
  • Visual display now also in yellow as early warning signal

Surge protection for instrumentation and control (I&C)

Protects processes. Secures your effectivity.

The VARITECTOR SPC series was specially developed for I&C applications and can reliably prevent overvoltage-related failures – e.g. in wind turbines. It has a two-part pluggable design. The VARITECTOR SSC series in terminal block design is available as a variant with tension clamp or screw connection technology. Both product series comply with IEC/EN 61643-21 and -22 and are suitable for industrial and process automation as well as for applications in building automation.

Surge protection for instrumentation and control (I&C)
Your advantages
  • The VARITECTOR Series VSPC and VSSC are tested according to product standard IEC/EN 61643-21
  • The VARITECTOR Series VSPC and VSSC can be installed in systems according to IEC/EN 61643-22
  • The VARITECTOR series VSPC and VSSC can be used in applications according to classes C1, C2, C3, and D1
  • A visual and electrical signaling function is available as an option

Surge protection for data interfaces

Protects know-how. Cares about your data.

VARITECTOR surge protection solutions effectively protect network components in low-voltage systems from frequently occurring transients, overvoltages, and voltage spikes. In this way, many errors in data transmission between controllers, computers, converters or sensors/actuators can be avoided just as effectively as data loss on storage media.

Surge protection for data interfaces
Your advantages
  • Protects your standard signals such as RS 485 and RS 232
  • Ethernet CAT.6 Protection with PoE+ function

Protects infrastructures. Secures your power supply.

To avoid failures due to overvoltage damage, you need reliable protection. The broad portfolio of VARITECTOR surge protection devices protects power, signal, and data transmission in all infrastructure systems - from power supply systems, signal boxes, and lock systems to digital control lines. The compact modules increase efficiency and reduce the effort required for maintenance, troubleshooting, and recertification. This alone pays for the investment after less than a year.

With our product wizard you can select the specifications of your desired lightning and surge protection products, and you will be shown an overview of all matching Weidmüller products.
