Figure 5-30 Example of a Current Terminal with Connection of 2 Single Cables
You can connect solid conductors as well as stranded-wire conductors with ring-type lug or bootlace ferrule.
For each connection, you can install up to 2 single cables of the same type and the same cross-section.
Bridges can be used as an alternative for horizontally arranged clamping points. If bridges are used, only ring-
type lugs may be used.
The following cable cross-sections can be used for the connection of single cables:
Cable cross-section AWG (American Wire Gauge) 14-10
(2.0 mm
2
to 4.0 mm
2
(0.0031 in
2
to 0.0062 in
2
))
Ferrule with plastic shroud L = 10 mm (0.39 in) or L = 12 mm (0.47 in)
Stripped length 15 mm (0.59 in)
For use without ferrule Use solid copper cables only.

NOTE
Always guide the solid conductor or stranded-wire conductor with bootlace from the left- or right-hand side
ferrule into the terminal. Making contact from the center is not permitted.
Mechanical Requirements
The fasteners and their associated components are designed for the following mechanical requirements:
Permissible tightening torque at clamping screw
2.7 Nm
For solid conductors, the max. permissible tightening
torque is 2 Nm.
Permissible tensile force for each connected
conductor
80 N following IEC 60947-1 (VDE 660, part 100)
Connections of Voltage Terminals
Connections of Voltage Terminals with Spring Clips
Fasteners
The fasteners for the voltage connection are part of the voltage terminal (housing side). They are made of a
stress-crack and corrosion-free alloy. The head shape of the clamping screw allows the use of a DIN 4.0 x 0.8
screwdriver or a PZ1 Phillips screwdriver. Siemens recommends a PZ1 Phillips screwdriver.
Connection Elements and Conductor Cross-Sections
The single cable connection type is available for the connection. You can connect solid conductors as well as
stranded-wire conductors with and without bootlace ferrule as single cables. Siemens recommends using twin
bootlace ferrules of series PN 966 144 made by Tyco Electronics for the connection of 2 single cables.
