Surge protection for instrumentation and control (I&C)

Overvoltage coupling along the conductor path may disturb or destroy sensitive signal inputs. It is important to provide protection in the immediate vicinity of I&C devices. Weidmüller's broad product range for the I&C sector offers products in a 2-piece, pluggable design and modular terminals for tension clamp or screw connection. These products are suitable for both binary and analogue signals. Weidmüller also offers other designs with integrated components such as gas discharge tubes or varistors. VARITECTOR stands for flexible and variable surge protection by Weidmüller, tested according to product standard IEC61643-21. The VARITECTOR series can be used in applications according to IEC 61643-22 / VDE 0845-3 for classes C1, C2, C3 and D1. The VARITECTOR SPC, SSC and MCZ OVP product families optimally combine electrical and mechanical properties. Size and easy handling play an important role. This surge protection is suited for confined spaces in industrical and process automation as well as in building automation applications.

Product group overview

	2-part, pluggable protection, VSPC series Pluggable arresters from the VSPC series Base elements for the VSPC pluggable components Supply and alert unit for VSPC R arresters Accessories for the VSPC series	The VARITECTOR SPC features a pluggable arrester which can be easily replaced or tested without any re-wiring. The V-TEST testing device enables an easy observance of maintenance intervals. The simple snap-on VSPC BASE allows for convenient mounting while simultaneously establishing a PE contact via the mounting rail. Featuring both, simple operation and high packaging density, the VSPC provides high-quality surge protection for all I&C signals. A coloured voltage marking allows maintenance staff to quickly identify the unit in the cabinet. This product line also features a complete range of accessories, such as the V-GROUND for earthing all sensor signals or the V-TEST connector for circuit measurements. A VSPC Locking Clip also fixes the pluggable arrester on the base to withstand even extreme loads. The VSPC R monitoring modules have an integrated message function which is monitored and controlled via the VSPC CONTROL UNIT. The base element with plugged-in arrester has a total height of 69 mm.

	1-level protection with screw connection, in terminal design, VSSC series with varistor (MOV) with gas discharge tubes (GDT) with suppressor circuit (RC combination with MOV) with suppressor diodes (TAZ) Accessories ( end plates)	Overvoltage protection with individual components

	3-, 2- or 1-level surge protection with tension-clamp connection, MCZovp series MCZ OVP 24 V AC/DC MCZ OVP 48 V UC MCZ OVP HF	Slimline surge protection terminals with tension-clamp connections, suitable for use in high-speed signal circuits. Weidmüller MCZ OVP surge protection terminals are characterised by their maximum protective function concentrated in a compact space of 6 mm. The tension clamp connection and direct earthing via the terminal rail contact results in a time-saving during installation. The MCZ OVP terminals are perfectly suited for confined spaces in process, industrial and building services automation.

	Cable Gland VCG SERIES	VARITECTOR Cable Gland (VCG) protects intrinsically safe circuits in IP67 applications Tested in accordance with IEC/EN 61643-21 Suitable for use in EX areas High protection class with IP67 Screw-in housing with different threads HART-compatible
