Tender specification sheets
Long specification Surge protection plug
for use in connection
with the base element
VSPC BASE 2CL for two
floating-ground driven
signal cables and ground,
e.g. for bus systems. Two-
stage protection circuit
consisting of coarse
protection, decoupling
resistors and fine
protection between the
signal wires and additional
coarse common mode
voltage protection to earth.
Mechanical identification
of the plug to the base
element according to
the switching type and
rated voltage. Protected
plug with coding pin and
counter-profile for the base
element. It is possible to
mark the plug.
Short specification
Surge protection plug for
base element VSPC BASE
2CL, transverse voltage
coarse and fine protection
for two floating-ground
powered IT signal cables,
coarse common mode
voltage protection to earth.
