Weidmüller VARITECTOR Lightning & Surge Protection

Weidmüller VARITECTOR provides lightning and surge protection solutions for electrical and electronic systems exposed to transient overvoltages. The portfolio covers several application areas, allowing protection concepts to be developed for power distribution, industrial control equipment and communication interfaces.

For energy systems, the VARITECTOR range includes Type I, Type II and Type III surge protection devices depending on the required stage of protection and selected product. Different devices can therefore be considered for incoming supply protection, downstream distribution and equipment-level surge protection.

In addition to power circuits, VARITECTOR includes solutions for instrumentation and control circuits as well as data interfaces. This allows surge protection to be coordinated across power, signal and communication systems within the same industrial installation.

Installation options include DIN-rail mounting and selected busbar-system configurations depending on product family. Applicable product ranges reference the IEC/EN 61643 series according to the selected device and application.

Typical uses include building infrastructure, industrial plants, process systems and power-system installations. Sea Star International can assist with selection based on network type, nominal voltage, protection class, installation position and the type of circuit or interface being protected.
