This method has
proved highly effective for decades. ∼18 chromium, ∼10 nickel). soft metal, Weidmüller’s terminal
rails are 2.
If terminal rail used PEN busbar, the following
criteria must observed:
• Only E-Cu aluminium profiles are allowed
• Short-circuit currents and thermal rated currents must be
taken into account
• The terminal rails are insulated contribution to
protective insulation
Stainless steel
Stainless steel collective noun for all kinds steel
(alloys) which are smelted special process and have a
high degree purity.
They can also used protective conductor busbar. this chapter, you will find range terminal
rails and profile rails for component installation, together
with end brackets for holding and isolating the components.
These guarantee firm installation and isolation. However, only after
the use certain consumables which are frequently not
taken into consideration that electrical installation finally
completed.8 1282250000 2012/2013

Plastic
The plastic terminal rail scores two counts: firstly, its
insulating properties, and secondly, its low weight.Terminal rails Introduction
Active and passive components, well intelligent
modules, are mounted terminal rails.
Aluminium
Aluminium second only copper its electrical
conductivity. According VDE 0100 part
540, for conductors with cross-sectional areas exceeding
10 mm2
, both protective and neutral conductors may
be grouped together single category conductors
designated PEN.
Terminal rails are made either steel, stainless steel,
aluminium, copper plastic, depending the area of
application. This
leads its use special applications where, for example,
clearance and creepage distances with respect the
mounting plate cannot achieved with the standard
terminal rails.
Weidmüller earth terminals the W-Series, Z-Series,
I-Series, SAK- and AKZ-Series comply with requirements
stipulated IEC 947-7-2.e. Aluminium
oxidises quickly air; thus passivated, offers excellent
corrosion protection.
Copper
Copper, heavy metal, has the best electrical conductivity
of all metals used. Weidmüller’s stainless steel terminal
rails have the following composition: CrNi 18-10
stainless steel (i.
Among metal DIN rails, has the lowest short-circuit
resistance, similar stainless steel. Stainless steel has much-enhanced
resistance corrosion.3 thick. One advantage its light weight.
Steel
The steel rail the most widely used DIN rail the market.
Weidmüller supplies components which show perfect
functional compatibility
