Surge protection for instrumentation, control and automation circuits 

VARITECTOR SPC VARITECTOR SSC EMC Set 

Pluggable surge protection 

For error detection and error 

messages as well as for monitoring 

instrumentation, control and 

automation circuits, Weidmüller 

developed the VARITECTOR SPC, 

its new families of surge protection 

devices. The VARITECTOR SPC, 

the pluggable surge protection, is 

characterised by highest protective 

functions with compact dimensions. 

With the VARITECTOR SPC R modules, 

error detection and error messages 

are realized by internal monitoring. Up 

to ten surge protection modules can 

be combined to transmit a message 

to the evaluation unit VARITECTOR 

SPC Control Unit. The advantage of 

all VARITECTOR SPC modules is that 

they are designed to be removed or 

exchanged during running operation 

- without interrupting the measuring 

circuit. 

The V-TEST unit is used for testing the 

function of the VARITECTOR SPC. It 

ensures that maintenance intervals can 

easily be adhered to, which is required 

by IEC 62305. 

For four binary signals or two analogue 

signals in just 17.8 mm of space are 

needed. The screw-free PE arrestor 

connection reliably enables the 

discharge of impulse currents up to 20 

kA (8/20 μs) and 2.5 kA (10/350 μs) 

via a grounded mounting rail. 

With a width of 6 mm in a compact 

terminal format 

The VARITECTOR SSC family of surge 

protection devices for I&C circuits was 

developed with compact terminal-like 

dimensions (only 6.2 mm wide). 

The VARITECTOR SSC family comprises 

over 100 devices, thus being able 

to offer a fitting solution for any kind 

of surge protection. This protection 

comprises current loops and binary 

signals for 5 V, 12 V, 24 V, 48 V and 

60 V. The terminals are equipped with 

complete integrated surge protection 

units or individual components such as 

varistors. 

Using a slotted-head Torx screw with 

a locking torque of 0.8 to 1.0 Nm, 

conductors ranging from 0.5 to 6 mm2 

are connected providing proection 

against vibration . 

The safe discharge of surges up to 20 

kA (8/20 μs) is realized by a snap-on 

connection to the mounting rail. A 

direct contact with the PE arrestor is 

established and excellent discharge 

properties are guaranteed for years. 

For precise identification, all 

VARITECTOR products are equipped 

with large-scale marking capabilities: 

Connections for equipment or 

individual devices are labelled and the 

various voltage levels are marked by a 

colour code. Due to this, components 

can be quickly identified in a switching 

cabinet, thus simplifying both service 

and commissioning. 

All VARITECTOR SPC and SSC products 

were tested in accordance with the 

latest standards (IEC 61643-21): In 

classes D1, C1 and C2, they fulfil the 

safe short-circuit mode when units fail 

to overload of required. 

The EMC set offers additional 

convenience for connections with 

shielded cables. The EMC set consists 

of the EMC connector, i.e. the shield 

connector, and cable ties with shield 

cover EMC tie. The conductor shield 

can easily be connected to the 

clamping yoke connections of the 

VARITECTOR SPC modules.

PROTECTION OF ANALOGUE SIGNALS 

Protection of analogue signals and 

current loops (CL) 

In practice, the most common signals 

are analogue signals, also called 

current-loop signals. In most cases, 

analogue signals are needed to 

verify limit values (e.g., maximum or 

minimum temperature). Mostly, these 

signals are used for long distances. 

The standard forms are: 

4 – 20 mA 

0 – 20 mA 

0–10 V 

In practice, for example two-wire, 

threewire and four-wire measurements 

without common reference potential 

are carried out. The more wires 

there are, the more precise the 

measurements get with the means 

of protection thus becoming more 

important as well.

Binary Signals 

Grounded Surge Protection 

For binary signals, there are two kinds 

of surge protection components 

available - those with a common 

reference potential and those without. 

Two-wire connections are usually made 

with a common reference potential. 

These signals are for example signals 

from binary sensors, actuators or 

indicators. 

Up to ten VSPC surge protection 

modules can be incorporated into one 

monitoring circuit. Using the V-Control 

unit, also line breaks or interruptions in 

the circuit can be signaled. 

1 

Practical examples include: 

- Limit switches 

- Push buttons 

- Position sensors 

- Photoelectric detectors 

- Contactors 

- Solenoid valves 

- Signal lamps 

The surge protection for floatingground 

(FG) models of binary signals 

is used in all applications, in which 

potential shifts may occur. These are 

mainly signals received in the field 

and transported over long distances. 

With this model, a gas discharge tube 

is introduced in series between the 

PE and the surge protection. This gas 

discharge tube inhibits coupling via PE. 

The surge protection for grounded 

models of binary signals is used 

mainly in those fields, in which all 

signals are laid directly to one star point 

or to one potential. 

7

SIMPLE AND PRECISE ISOLATION 

The integrated disconnect lever 

guarantees that the measurement / 

control circuit can be quickly & precisely 

switched off to test the signal path 

TESTING EASE 

All connections are easily tested utilising 

the integrated test socket (Torx®/slot 

headed scew) and test plug. 

IEC COMPLIANT 

All VARITECTOR products comply with the 

latest IEC 61643-21:2008 requirement 

and with categories D1, C1, C2 and C3 

according to IEC 61643-22.

Accessories 

The V-Test is a compact, portable instrument for the 

Varitector SPC pluggable surge protection (VSPC series) and 

surge protection for power distribution, PUI and II series. 

With this instrument, the Weidmüller surge protection can be 

tested for protective function in accordance with the required 

test periods as stipulated by IEC62305 (DIN VDE 185 Part 3). 

In a backlit display, the measurement result is indicated with 

„ok“ or „not ok“ for each component.
