IMPORTANT INFORMATION
NOTICE: Read these instructions carefully, and look at the equipment to become familiar
with the device before trying to install, operate, or maintain it. The following
special messages may appear throughout this documentation or on the equipment
to warn of potential hazards or to call attention to information that clarifies or
simplifies a procedure.
The addition of this symbol to a Danger or Warning safety label indicates that an
electrical hazard exists, which will result in death or serious injury if the
instructions are not followed.
This is the safety alert symbol. It is used to alert you to a potential personal injury
hazard. Obey all safety messages that follow this symbol to avoid possible injury or
death.
DANGER
DANGER indicates an imminently hazardous situation which, if not avoided,
will result in death or serious injury.
WARNING
WARNING indicates a potentially hazardous situation which, if not avoided,
can result in death or serious injury.
CAUTION
CAUTION indicates a potentially hazardous situation which, if not avoided,
can result in minor or moderate injury with or without equipment damage.
NOTICE
NOTICE, used without safety alert symbol, indicates a potentially hazardous
situation which, if not avoided, can result in equipment damage.
When electrical equipment is in operation, dangerous voltage will be present in
certain parts of the equipment.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
⚫Only qualified personnel, trained, authorized and familiar with the device
and all the safety instructions in the general Safety Guide (SFTY/5LM/L11
or later version) and appropriate Chapter 5, Chapter 10, Chapter 11,
Chapter 12 and Chapter 13 of this manual, shall work on installation,
connection, commissioning, maintenance or servicing of this device.
Failure to follow these instructions will result in death or serious
injury.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
⚫Switch off the auxiliary power supply before any work in the terminal strip
area.
⚫Switch off all the power supplies in connection to the equipment before
any work in the terminal strip area to isolate the device.
⚫Do not touch the terminal strip area when equipment is in operation.
⚫Do not remove or add wires in the terminal strip area when equipment is
in operation.
⚫Short-circuit the system current transformers before disconnecting wires
to the transformer board (valid only for pin terminals, not required for ring
terminals which have a shortening block).
⚫A protective conductor (ground/earth) of at least 1.5 mm2 must be
connected to the protective conductor terminal on the power supply board
and on the main relay case.
⚫Do never remove the protective conductor connection to the device casing
as long as other wires are connected to it.
⚫Where stranded conductors are used, insulated crimped wire end ferrules
must be employed.
Failure to follow these instructions will result in death or serious
injury.
Note: Regarding the appropriate wiring connections of the equipment refer to the
document Px3x_Grounding_Application_Guide_EN_h.pdf.
WARNING
HAZARD OF UNSAFE OPERATION
⚫Only qualified personnel, trained, authorized and familiar with the device
and all the safety instructions in the general Safety Guide (SFTY/5LM/L11
or later version) and appropriate Chapter 5, Chapter 10, Chapter 11,
Chapter 12 and Chapter 13 of this manual, shall work on installation,
connection, commissioning, maintenance or servicing of this device.
⚫Proper and safe operation of this device depends on appropriate shipping
and handling, proper storage, installation and commissioning, and on
careful operation, maintenance and servicing. For this reason only
qualified personnel shall work on or operate this device.
⚫Any modifications to this device must be in accordance with the manual. If
any other modification is made without the express permission of
Schneider Electric, it will invalidate the warranty, and may render the
product unsafe.
Failure to follow these instructions can result in unintended
equipment operation.
The signals MAIN: Blocked/faulty and SFMON: Warning (LED) are
permanently assigned to the LEDs labeled OUT OF SERVICE and ALARM and can
be assigned to output relays to indicate the health of the device.
It is recommended that the signals MAIN: Blocked/faulty and
SFMON: Warning (LED) are communicated to the substation automation
system for alarm purposes, using hardwiring via output relays or the
communication interface.

1 Application and Scope
1.1 Overview
The P638 differential protection device is designed for fast and selective short
circuit protection, ground fault protection, and overload protection of
transformers in railway applications (two-winding arrangement) in railway
substations with nominal frequencies of 16.7, 25, 50 or 60 Hz (settable).
This protection device may be installed in standard-gauge railway substations
operating on any normal frequency and voltage level.
The selection of protection functions has been optimised for transformer
protection in a wide range of substations, and at the same time they offer back-
up protection for both incoming and outgoing feeders.

Fig. 1-3: P638 in a 84 TE sized case with text display.
Fig. 1-4: P638 in a 84 TE sized case with graphic display.
The control functions are designed for the control of up to ten electrically
operated switchgear units equipped with plant status signaling and located in the
bay of a railway substation.
The number of external auxiliary devices required is largely minimized by the
integration of binary signal inputs operating from any auxiliary voltage, and
versatile relay output contacts, by the direct connection option for current and
voltage transformers, and by the comprehensive interlocking capabilities. This
simplifies the handling of switch protection and control technology from planning
to commission.
During operation, the user-friendly interface makes it easy to set the device
parameters and allows safe operation of the substation by preventing
nonpermissible switching operations.
All main functions are individually configurable. The user can adapt the device
flexibly to the scope of protection and control required in each particular
application.
