Weidmuller Pluggable Surge Protection Varitector SPC are now CSA C1D2 Approved
March 25 2015
Weidmuller’s Varitector range offers low-cost, highdensity surge protection options for lightning and other transient protection in industrial control equipment. UL (497B) and CSA C1D2 approved, Varitector is ideally suited for signaling (I/O) applications such as analog current and voltage loops, DC and AC status signals and a wide variety of serial interface and telephone network installations. Models for hazardous area and SIL options are available. The Varitector range includes two construction formats, VSSC and VSPC. VSSC models feature 4- or 6-pole rugged, compact terminal-sized housings. VSPC models feature a two part, plug-and-base format for easy arrestor replacement without re-wiring. Both formats are DIN-rail mounted, rated for discharge currents up to 20kA (8/20μs), and provide a combination of wire-to-ground and wire-to-wire protection.
All Varitector models include high quality field connections and are grounded via the DIN-rail. A combination of gas discharge tubes, varistors and suppression diodes in single or multi-stage configuration are used to protect nominal voltages between 5 VDC and 230 VAC. Status monitoring options help ensure continued protection. VSPC modules feature local and remote signaling of arrestor status, while many of the VSSC6 models have an option for an integral LED, which signals when module replacement is required. The Varitector range complements the Weidmuller’s SPD II range of surge protectors for low voltage power distribution applications. Taken together, these products provide extensive DIN-rail mounted surge protection capability for industrial installations.
