Weidmuller has introduced 80 VSSC models to its Varitector range of surge protection components, providing customers new high-density options for lightning and other transient protection for control equipment. Recently assigned UL (497B) approvals, the company says the new VSSC range completes its Varitector surge product offering for signaling, which includes hazardous area and SIL options. The new VSSC models feature 4- or 6-pole rugged, compact, terminal-sized housings for din-rail mounting. Intended for measurement, control, and fieldbus applications, typically in water and waste sectors, VSSC is rated for discharge currents up to 20kA (8/20μs). Weidmuller says the new VSSC range complements the existing SPD II range aimed at low-voltage power distribution applications, comprising an extensive Din-rail mounted surge protection offering for industrial installations. Both ranges provide a combination of wire-to-ground and wire-to-wire protection, include high quality terminations for field connections, and make a ground path via the (grounded) 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. They protect analog current and voltage loops, DC and AC status signals, and a wide variety of serial interface and telephone network installations. A status-monitoring option helps ensure continued protection by means of integral LEDs for many VSSC6 (6-pole) models, which show when a replacement module is needed. Other features include colored product marking to help users quickly identify different working voltages between modules mounted together, models for protecting floating signals, and models with integral disconnects to make testing easy.
