Rated normal current and maximum short-time current (1) Functional unit with circuit breaker. 2) Functional unit with safety contactor (3). Functional unit with switch and fuse combination (DI cabinet) (8) Rated current according to installed fuses, see documentation.
No sources of interference due to external influence during operation – In accordance with IEC/EN avoidance of internal arcs has top priority – The IEC/EN Table 102, recommendations include the use of gas-. The operating company is free to choose a switchgear unit with internal arc classification IAC according to the applicable standards.
Functional overview
5 Low voltage auxiliary equipment and protection, monitoring and control units are in a control cabinet which is separate from the medium voltage part. TU 4 control cabinet Low voltage. auxiliary equipment and protection, monitoring and control units are in a control cabinet which is separate from the medium voltage part. Opening the access panel to the medium voltage connections and fuses is possible only when the earthing switches upstream and downstream of the fuses are closed.
The voltage presence indicator is located on the front of the functional unit, integrated into the switch's control panel. For access to the main rails from the front of the switchboard, a removable panel is provided at the bottom of the LV cabinet.

Safety and protection of persons and property
A motorized version of the truck allows the circuit breaker to be inserted and removed remotely. A shunt closing release operates to close the circuit breaker when the voltage at the release terminals is between 85% and 110% of its rated voltage. A shunt opening release opens the circuit breaker when the voltage at the release terminals is between 70% and 110% (in the case of direct current) - or between 85% and 110% (in the case of alternating current) - of its rated voltage.
The second shunt opening release operates to open the circuit breaker when the voltage at the release terminals is between 70% and 110% (in the case of direct current) - or between 85% and 110% (in the case of alternating current) - of the voltage his nominal. The closing of the circuit breaker is possible when the voltage at the release terminals is equal to or exceeds 85% of its rated voltage.
Specific applications according to IEC 62271-100
LF circuit breaker
Mechanical interlock of contactor in open position to prevent winding in or out with closed contacts. These curves show the maximum value of the limited interrupting current Ic (in kA peak) as a function of the value Ip (in kA rms) of the assumed current that would occur in the absence of protection. Latch coils are inserted into the circuit at the end of the contactor stroke.
Movable contact rotation is driven by a quick-acting mechanism that is independent of the operator. To increase the cooling of the arc, a relative motion is created between the arc and the gas.
Voltage Transformers for MCset
In the withdrawable fuse version, the live part is completely encased in an epoxy resin, which provides both electrical insulation and excellent mechanical strength. With one insulated MV terminal, for connection between neutral and phase conductors in 3-phase systems with withdrawable MV fuses. This transformer supplies current to the coil to keep the contactor's magnetic circuit closed.
Schneider Electric has compiled a list of current transformers suitable for use with digital protection devices to facilitate the determination of accuracy characteristics.
The Easergy P3 protection relay concept has been expanded with a number of features that make installing and testing the relays even more efficient and user-friendly, such as the virtual injection test that is accessible with the eSetup Easergy Pro setup software. The Easergy P3 protection relay family is based on proven technology concepts developed in close cooperation with customers. The Easergy P3 feeder manager was developed to meet basic protection needs for OEMs, utilities and industrial applications.
Thanks to its cost-effective and flexible design, the Easergy P3 offers an excellent alternative for various protection applications. Easergy P3 combines further protection functions such as directional earth fault for supply and motor protection.
Easergy P3 standard Universal applications

Setup and download/upload is much faster thanks to the unique eSetup Easergy Pro setup software, which dramatically improves ease of use.
The informative human-machine interface displays the information the user needs with the support of customized explanatory texts.
Protection, monitoring & control
The shorter the operating time of the arc flash protection unit, the smaller the damage caused by the arc fault and the shorter the possible power failure. Limited damage also means limited need for repairs and enables quick restoration of the power supply. Preventive maintenance can be difficult in severe operating conditions also due to limited accessibility and visibility of the contacts.
Thanks to its very compact footprint and its wireless communication, the Easergy TH110 allows an easy and widespread installation at all possible critical points without affecting the performance of the MV Switchgears. Specific monitoring algorithms make it possible to detect drift from the threshold based on the specific installation characteristics, also regarding the variable loads or abnormal behavior coming from phase comparison.
Key benefits
Loose and faulty connections cause an increase in resistance in localized points which will lead to thermal runaway until the complete failure of the connections. Harsh environment due to pollution, condensation and strong temperature shifts is one of the most critical causes of failure due to accelerated aging. Easergy CL110 is connected to the Substation Monitoring Device (SMD) which harvests the data for local signal, data analyzes and nearby display.
Using Zigbee Green Power communication protocol, the Easergy CL110 ensures reliable and robust communication that can be used to create interoperable solutions evolving in the Industrial Internet of Things (IIoT) era. The Easergy CL110 provides accurate temperature monitoring of the metal surface in direct contact with it.
