Self-Powered device
No auxiliary power needed. The WIC1 relays harvest the
required supply energy from the current measurement signals.
Dual-Powered variant
A dual (redundant) powered variant is available in order to enable e.g. communication(#) and early ground (earth) fault detection.
Ultra Fast Boot-uptime
With a start-up time of less than 1 cycle, the WIC1 already protects your equipment whilst other devices are still booting. What if someone is switching onto a fault although the system is still grounded during maintenance? The WIC1 will issue a trip signal almost immediately.
Individual
parameterization
With the WIC1 g2, you have all the options to configure the system according to your individual requirements. Conveniently via the „Smart view“ software (Smart view is the free software by SEG Electronics for easy configuration and evaluation), via DiggiMEC, or traditionally manually via DIP/HEX switches.

parameterization
With the WIC1 g2, you have all the options to configure the system according to your individual requirements. Conveniently via the „Smart view“ software (Smart view is the free software by SEG Electronics for easy configuration and evaluation), via DiggiMEC, or traditionally manually via DIP/HEX switches.
Communication
The WIC1‑4 features the Modbus RTU protocol via RS485 interface, or Modbus TCP via electrical or optical Ethernet.
Retrofit - No Drilling,
no Sawing
The WIC1 has the same form-factor as the predecessor. You can mount it into the cabinet in just a few minutes. No cabinet needs to be redesigned. No drilling, no sawing will be necessary. You can re-use the previously installed WIC1 CTs: Just switch over the connection cables. The first DIP switch blocks (WIC1-2) / HEX switches (WIC1-3) have the same function as the first WIC1 version, so that the settings are quickly copied.

The WIC1 family is a series of self-powered / CT powered protection relays, designed for harshest environments. The WIC relay family does not need auxiliary energy since they are CT powered. A dual/redundant powered variant enables communication options in addition to the power outage safe protection core. The main applications are:
- Protection of Ring Main Units for Power Distribution
- Protection of Step-Up Transformers e.g. for Wind and Solar Power
- Protection of Feeders
- Current based protection when auxiliary power is not available or too costly
- Backup Protection – available in absence of auxiliary power
- Disaster recovery – Blackstart capability after (short or long lasting) outages – reliable protection, when other protection relays fail because of drained battery rooms
More great features
- Super fast and easy mounting
- Super fast and easy setting
- Made for Harsh Environment: It is no problem for the WIC1 if the RMU / Transformer is in an area with harsh climate, for example high humidity all the year, or an average temperature above 50°C.
- Ground Current: The WIC1 offers calculated and measured 1 A ground Current (option).
- Tripping Characteristics: For inverse-time overcurrent protection, you can select out of 12 characteristics (ground overcurrent: 13)
Four variants -
all possibilities.
Four WIC1 g2 device variants are available to meet a wide range of requirements. For example, the device variants with DIP or HEX switches allow for manual configuration.
The optional DiggiMEC® interface device enables configuration of all device variants via the integrated LCD display and switches, providing access to extended setting ranges and additional protection functions. The DiggiMEC® also allows the WIC to be connected to a Windows PC via USB-C, so the SEG configuration and analysis software „Smart view“ can be used to easily and conveniently configure the WIC1 or to transfer measurement and fault data from the WIC1.
A self-powered WIC1 variant is also available, which additionally supports SCADA communication.

System Functional Overview
The WIC1 is a CT-powered protection relay with minimal space requirement (125 x 170 mm), that complies with the highest demands on a digital protection device. Simple but safe wiring, high electromagnetic interference immunity, uncomplicated adjustment and the ability to scale to different power quantities of the switchboard, helping the switchgear manufacturer to
minimize costs. System Overview:
Additional System Components
The WIC1 g2 is optimized for operation with specially designed, highly efficient CTs developed by SEG. If the use of 1 A (or 5 A) standard CTs is mandatory (for technical or historical reasons) it is possible to connect via the SEG PC4 adapter CTs between the 1 A CTs and the WIC1. Below is an overview of the available optional components:
- Optional DiggiMEC® Nano HMI [for more info about the DiggiMEC® click here]
- WIC1 wide range CT [Image: 1]
- PC4 Adapter [Image: 2]
- Flag indicators [SEG offers two mechanical flag indicators – WI1SZ4 and WI1SZ5 – as accessories for the WIC1. With the DiggiMEC®, there are also up to three flag indicators available.]
- SEG configuration and analysis software „Smart view“ [Image: 3]
If the DiggiMEC® user interface is connected to the WIC1, it is also possible to connect a PC to the USB interface of the DiggiMEC®. Via PC you can then simply and conveniently execute the parameterizing and analyzing software „Smart view“ and enable the user to make all settings via this connection, or to save settings to a file on the PC, or retrieve measured values or trip event data.

DiggiMEC® - Nano-HMI with up to three integrated mechanical flag indicators
The DiggiMEC® is an upgrade option to the WIC1 family, It fits into a standard door cutout of 92 mm × 45 mm [DIN IEC 61554]. Its display can visualize measuring values on site. Moreover, the DiggiMEC® provides access to the protection parameters that are always exclusively inside the WIC relay. The Nano-HMI offers integrated Flag Indicators and configurable LEDs and can be mounted in no time and without any drilling.
Software settings (offline created) can be loaded into the WIC1 relays via the USB-C port of the DiggiMEC®. Just connect the DiggiMEC® and WIC1 relay via a standard Ethernet cable.
