The SIA-B is Dual & Self-powered Overcurrent and Earth Fault Protection Relay, using the operating current through three specific current transformers fitted on the lines. These transformers are also used to obtain current measurements. Besides, SIA-B can be used with an auxiliary power supply (24-230Vac/dc). The relay can be also supplied by a USB cable connected to the laptop, with the USB KITCOM adapter or a standard power bank.
The protection relay offers the advantage in self-powered mode, which starts up from 0.4 times the minimum primary current of the CT (three-phase current).
SIA-B is suitable for RMUs, SF6 insulated, and compact switchgear, in those installations where the space is critical, making the maintenance much more manageable and its lightweight helps the customer to save costs in transport.
The SIA-B is an OC&EF Protection Relay with Self-powered and dual powered (self-powering + auxiliary power) options.
Specific current transformers. The relay is self-powered using the operating current through three specific current transformers fitted on the lines. These transformers are also used to obtain current measurements.
Auxiliary power supply Besides. The SIA-B can be used with an auxiliary power supply (24- 230Vac/dc). The relay can be also supplied by a USB cable connected to the laptop, with the USB KITCOM adapter or a standard power bank.
Internal commissioning battery. Included (Lithium battery: 20 years lifetime), as optional.
Metallic box with a high electromagnetic compatibility level (EMC) and wide range of operating temperatures.
Really low start-up levels. In self-powered mode, SIA-B starts up from 0.4 times the minimum primary current of the CT (three-phase current).
Test menu. Allows the trip circuit to be tested before the transformation centre is powered up.
Bistable magnetic indicator (flag) which indicates the trip condition, maintaining its position even though the relay loses the supply.
Self-diagnosis of the relay status (WATCHDOG) through a LED.
Low power consumption.
Communications Ports. To allow communication, relays are provided with a local micro-USB front port and with an optional remote communication RS485 port (Modbus RTU protocol) on the rear side.
Trip output for a low power coil. The SIA-B is provided with a trip output for a low power coil (24 Vdc – 135 mJ) and depending on the model, 1 external trip input and 2 configurable outputs.
Non-volatile RAM memory. The SIA-B is provided with non-volatile RAM memory in order to store up to 100 events and disturbance fault recording (DFR – 4 fault reports in data format), maintaining date & time thanks to its internal RTC (Real Time Clock) even without power supply.
No external batteries. The installation and subsequent maintenance of external batteries are eliminated. The operating costs of the centre are reduced.
Compact size. Its compact size makes SIA-B easy to install and its lightweight helps the customer to save costs on transport.

Communication Software for all Fanox Protection Relays MV Range
The SICom PC software has been designed and programmed to gain access to all of Fanox relays information, modify the settings and configuration, check states and measurements, and to analyse and save events and fault reports using a graphic-friendly user interface.
SICom software works with the Windows® Windows 7, Windows 8, Windows 8.1, and Windows 10 operating systems.
- General data reading: Complete model, Version, Serial number, etc.
- States reading
- Measurements reading
- Reading and changing settings
- Reading and changing the configuration
- Reading and deleting events
- Reading and deleting fault reports
- Reading and deleting demand current (load data profiling)
- Reading and saving oscillographic records in Comtrade format
- Changing the user passwords
- Saving and Loading settings files
- Saving and Loading configuration files
- Saving events and fault reports
- Saving demand current (load data profiling)
- Date-time synchronization
- Configuring the communication parameters
- Reading and changing counters
- Commands for opening and closing the circuit breaker and block/unblock the recloser
- Configuration of the inputs
- Configuration of the outputs
- Configuration of the causes that start a Fault Report
The update of the software does not require any user´s action; this is, if the computer is connected to the Internet, SICom updates itself when it is started.
It will allow you to prepare all the settings and relay configurations without having the relay connected to the PC (offline mode), reducing engineering and commissioning time.
SICom program uses Modbus protocol, so only the ports with this protocol can be used to establish the communication.
