General ordering data
Order No. 1063940000
Type VSSC4 SL FG 48VAC/DC Ex
Version Surge protection for instrumentation and control
GTIN (EAN) 4032248829361
Qty. 5 pc(s).
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.
