2 Important Notes
This section includes an overall summary of the most important safety
requirements and notes that are mentioned in each individual section. To protect
your health and prevent damage to devices as well, it is imperative to read and
carefully follow the safety guidelines.
2.1 Legal Bases
2.1.1 Subject to Changes
WAGO Kontakttechnik GmbH & Co. KG reserves the right to provide for any
alterations or modifications. WAGO Kontakttechnik GmbH & Co. KG owns all
rights arising from the granting of patents or from the legal protection of utility
patents. Third-party products are always mentioned without any reference to
patent rights. Thus, the existence of such rights cannot be excluded.
2.1.2 Personnel Qualifications
All sequences implemented on 787 Series devices may only be carried out by
electrical specialists with sufficient knowledge in automation. The specialists must
be familiar with the current norms and guidelines for the devices and automated
environments.
2.1.3 Use of the 787 Series in Compliance with Underlying
Provisions
The 787 Series power supply system provides DC voltage to electric or electronic
devices, such as industrial control systems or display, communication and
measuring devices.
The devices have been developed for use in an environment that meets the IP20

12.5 mm diameter is assured; protection against water damage is not ensured.
Unless otherwise specified, operation of the components in wet or dusty
environments is prohibited.
The devices are designed for installation in an enclosure. Under no
circumstances may they be used in control systems for planes or in nuclear
facilities, as any malfunction in these applications could result in severe injuries
or risk of death.

2.2 Safety Advice (Precautions)
For installing and operating purposes of the relevant device to your system the
following safety precautions shall be observed:
Do not work on devices while energized!
All power sources to the device shall be switched off prior to performing any
installation, repair or maintenance work.
Installation only in appropriate housings, cabinets or in electrical operation
rooms!
Always install devices of the 787 Series in enclosures, cabinets or electrical
equipment rooms which can be closed and locked. Ensure that access to this
equipment/these rooms is possible only by authorized specialists with the
appropriate key or tools.
Do not use these devices in control systems for planes, trains or nuclear
facilities!
Never use these devices in control systems for planes, trains or nuclear facilities,
as any malfunction in these applications can result in severe injuries or risk of
death!
Ensure a standard connection!
To minimize any hazardous situations resulting in personal injury or to avoid
failures in your system, the data and power supply lines shall be installed
according to standards, with careful attention given to ensuring the correct
terminal assignment. Always adhere to the EMC directives applicable to your
application.
Switch off power supply to defective device!
Switch off power supply to the device immediately if the device malfunctions or is
damaged! Control systems connected to the device may also be damaged!
Return the defective device directly to WAGO.

787-1668/0000-0080 Electronic Circuit Breaker
Manual
Version 1.1.0, valid from firmware 2.4.0
Do not plug in or disconnect the female connector while a load is applied!
Only plug in or disconnect the female connectors when the device is not live!
Failure to observe this can result in damage to the contacts due to arcing!
Plug the female connectors all the way into the male connectors!
Always plug the female connectors all the way in to the male connectors. This
ensures proper contact at all times.
Attach the free ends of the conductors using a strain relief device!
Female connectors can be pulled out of the male connectors by high vibration
levels or shock impacts!
Provide appropriate strain relief means to attach and cap any free ends of the
conductors!
Protect the components against materials having seeping and insulating
properties!
The components are not resistant to materials having seeping and insulating
properties such as: aerosols, silicones and triglycerides (found in some hand
creams). If you cannot exclude that such materials will appear in the component
environment, then install the components in an enclosure being resistant to the
above-mentioned materials. Clean tools and materials are imperative for
handling devices/modules.
Clean only with permitted materials!
Clean housing and soiled contacts with propanol.
Do not use any contact spray!
Do not use any contact spray. The spray may impair contact area functionality in
connection with contamination.
Do not reverse the polarity of connection lines!
Avoid reverse polarity of data and power supply lines, as this may damage the
devices involved.

3 Device Description
The 787-1668/0000-0080 electronic circuit breaker reliably protects up to 8 load
circuits against short circuiting and overloading. The 24 VDC input voltage
applied to 8 output channels, each of which can be provided with separate fuse
protection:
Table 3: Channel Fuse Protection
Version
Fuse Protection per Channel
787-1668/0000-0080
1 A, 2 A, 3 A, 4 A, 6 A, 8 A, 10 A
The electronics can accommodate brief current peaks.
The IO-Link interface can be used to set all listed trip currents. The device also
has 8 rotary switches which can be used to set 5 different trip currents.
The actual status of the output channel is indicated by a multi-colored LED.
In the event of a short circuit or overloading, the individual channel is de-
energized after a defined trip time.
Wait for temperature to return to normal!
If a channel has been de-activated due to short-circuiting or overloading, wait
until the temperature returns to its normal range (cooling period) before re-
activating the channel.
The terms “switched ON” and “switched OFF”, as well as “tripped” are used in
this manual. To clearly delineate these terms, they are explained as follows:
Table 4: Definition of Terms
Designation
Definition
Switched ON
The user has activated the electronic circuit breaker
manually from the button or by a corresponding
interface command. The load circuit is closed, the
current flows.
Switched OFF
The user has deactivated the electronic circuit
breaker manually from the button or by a
corresponding interface command. The load circuit
is open, the current flow is interrupted.
Tripped
The electronics of the electronic circuit breaker have
been tripped due to overcurrent, undervoltage or
overvoltage. The load circuit is open, the current
flow is interrupted.
