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

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.

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 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

LSC 2A • Safe access to compartment • With power flow in busbar and the other units • MV Cables must be earthed

Maintainability of one functional unit allowing normal service of the remaining units of the switchboard (busbar in a separate compartment)

Partition Class I or M • Classification based on electrical field presence in safe access compartment

Partition Class PM Personnel comfort during maintenance

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.

• All partitions and shutters of safe access compartment shall be metallic with some current carrying capacity

Partition Class PI • Partitions or shutters may be partially or totally of Definition insulating material

“Metal enclosed” compliant during maintenance Applicable mainly to withdrawable system

Internal Arc Class IAC • Classification based on consequences of internal arc on personnel safety

Accessibility Types • A : restricted to authorized personnel only. • B : unrestricted, including general public.

IAC classified Personnel safety in case • No projection of parts of internal arc towards accessible sides • No ignition of indicators

Motorpact complies with AFLR type

Safety in case of internal fault during service condition Demonstrated by type tests (completely defined by the standard)

IAC not classified • No tests performed to assess behavior of enclosure under arc conditions

• Enclosure Identification code: F - for Front side • L L - for Lateral side R - for Rear side
