FVNR base module description Direct stator starting on full voltage
Locked rotor current on starting is around 4 to 7 In depending on motor characteristics Starting time of 1 to 10 seconds depending on the moment of total inertia (motor + machine), motor torque and load torque The network must be able to withstand the starting current without disturbing other loads The machine being driven must be able to withstand the mechanical impact due to the motor torque This mode is very popular (simple, robust, not expensive)

Auto Transformer module description Reduced voltage by auto-transformer
This system is recommended for high power motors. It has the advantage of not dissipating energy. It can be used to obtain, for the same decrease in current, less reduction in torque than with the reactor starter.

Reduced Voltage SoftStart motor starter (RVSS) SoftStart motor starter provides smooth, stepless acceleration and deceleration regardless of the load. This starting method lowers the starting current of the motor, reduces electrical stresses on the network and the motor. It reduces peak starting torque stresses on both the motor and mechanical load components, thereby providing longer service life and less downtime.

Locked rotor current on starting is around 4 to 7 In depending on motor characteristics Starting time of 1 to 10 seconds depending on the moment of total inertia (motor + machine), motor torque and load torque The network must be able to withstand the starting current without disturbing other loads The machine being driven must be able to withstand the mechanical impact due to the motor torque This mode is very popular (simple, robust, not expensive)

Auto Transformer module description Reduced voltage by auto-transformer
This system is recommended for high power motors. It has the advantage of not dissipating energy. It can be used to obtain, for the same decrease in current, less reduction in torque than with the reactor starter.

Reduced Voltage SoftStart motor starter (RVSS) SoftStart motor starter provides smooth, stepless acceleration and deceleration regardless of the load. This starting method lowers the starting current of the motor, reduces electrical stresses on the network and the motor. It reduces peak starting torque stresses on both the motor and mechanical load components, thereby providing longer service life and less downtime.

First stage : C is open A and B are closed B must be closed before A.
Second stage : A remains closed C remains open and B is opened
Third stage : A remains closed B remains open and C is closed
The current path is shown in red. It is obvious that the motor is always supplied even during the second stage, when B is open.
First stage : the motor is starting with reduced voltage. Second stage: the motor is running in series with part of the autotransformer winding. Third stage: the motor runs at full voltage.

Motorpact to IEC 62271-200
Fully enclosed in metal enclosure and having some current carrying capacity
Loss of Service Continuity Class (LSC)
• Architecture based on “safe compartment access”
Several levels of service continuity during maintenance
LSC 2A
• Safe access to compartment • With power flow in busbar and the other units • MV Cables must be earthed
LSC 2B
Maintainability of defined parts with no need of cable disconnection (separate cable compartment) • Safe access to compartment • With power flow in busbar and the other units • MV Cable in separate compartment • Cable of unit under maintenance can remain energized
Maintainability of one functional unit allowing normal service of the remaining units of the switchboard (busbar in a separate compartment)

Motorpact to IEC 62271-200
Fully enclosed in metal enclosure and having some current carrying capacity
Partition Class I or M
• Classification based on electrical field presence in safe access compartment Personnel comfort during maintenance
Partition Class PM
• All partitions and shutters of safe access compartment shall be metallic with some current carrying capacity
“Metal enclosed” compliant during maintenance Applicable mainly to withdrawable system
3.110 Shutter Part of metal-enclosed switchgear and controlgear that can be moved from a position where it permits contacts of a removable part, or moving contact of a disconnector to engage fixed contacts, to a position where it becomes a part of the enclosure or partition shielding the fixed contacts.
Partition Class PI
• Partitions or shutters may be partially or totally of Definition insulating material
Electrical and mechanical safety according to IEC 60466 or 60137

Internal Arc Class IAC
• Classification based on consequences of internal arc on personnel safety
IAC classified Personnel safety in case • No projection of parts of internal arc towards accessible
sides • No ignition of indicators
Safety in case of internal fault during service condition Demonstrated by type tests (completely defined by the standard)
Accessibility Types
• A : restricted to authorized personnel only. • B : unrestricted, including general public. • Enclosure Identification code: F - for Front side • L L - for Lateral side R - for Rear side
Motorpact complies with AFLR type
IAC not classified
• No tests performed to assess behavior of enclosure under arc conditions
