The world is becoming more and more digital. Technical infrastructure and plants getting increasingly complex and sensitive. Due to the increasing connections and interactions of components and systems, the protection of individual areas is becoming of decisive importance and surge protection plays a more important role than ever before.
Due to the increasing digitalization and inter-communication of various electronic devices, electronic devices are now much more susceptible to transient and high-energy voltage peaks. With Weidmüller lightning and surge protection for energy, data and signals, you can protect your system and prevent downtimes.
As a long-term, innovative partner, Weidmüller stands for reliable high-quality products for surge protection. In-depth specialist knowledge and hundreds of tailor-made surge protection solutions make us your ideal partner. With our broad and comprehensive VARITECTOR product portfolio we offer surge protection for energy systems, for instrumentation and control, and for data interfaces.
VARITECTOR PU AC S-line
With increasing digitalisation, the infrastructure of intelligent devices and systems is becoming more and more sensitive to interferences. Besides, cost and competition are forcing manufacturers to improve compactness and efficiency of their products. The innovative gas arrester technology of our VARITECTOR PU AC S line enables a particularly space-saving design with only 18 mm width per pole. For excellent surge protection with a slim design and an attractive price/performance ratio.
Space savings of 50 % due to reduced width
Fuseless operation up to 315 A
Energetically coordinated as type I, II and III
More efficient installation
Surge protection for energy systems
In the energy sector, the VARITECTOR portfolio offers lightning and surge protection solutions for voltages from 75 V to 1,500 V for diverse applications in energy supply, renewable energies, water management, and the process industry. The products are tested according the valid product standards EN 61643-11 (AC), EN 50539-11 (PV) and UL 1449 Ed. 4.
The arresters are tested according to product standard IEC/DIN EN 61643-11 and UL 1449 Ed.4
The arresters can be installed in systems according to IEC/DIN 61643-12 and IEC 62305-4
No back-up fuse needed up to 315 A
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)
Weidmüller's broad product range of VARITECTOR SPC for the I&C sector offers products in a 2-piece, pluggable design and VARITECTOR SSC modular terminals for tension clamp or screw connection.
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
