Hello,

Below are the applicable standards for APFC panel with definition - 

●●IEC 61921: (Power Capacitors- Low voltage power factor
correction banks) is the international standard applicable for Low
Voltage Power Factor Correction Banks and Automatic Power
Factor Correction (APFC) equipments intended to be used for
power factor correction purposes, equipped with built in switch
gears and control gears. The guidelines for design, installation,
operation and safety of APFC panels are followed based on this
international standard.

●●IEC 60831: Part 1 & 2-Shunt power capacitors of the self healing
type for a.c systems having rated voltage up to and including 1kV.

●●IEC 61439-1: Low voltage switchgear and control gear
assemblies. Particular requirements for low-voltage switchgear
and control gear assemblies intended to be installed in places
where unskilled persons have access for their use-Distribution
boards.

●●IEC 60947: Low Voltage Switchgear
Part 2: Molded Case Circuit Breakers & Air circuit Breakers
Part 4: Power Contactors
Part 4-3: Thyristor Switch

●●IEC 60076-6: Reactors.

●●IEC 60529: Degree of protection provided by enclosure (IP
code).

●●IEC 60664-1 / IEC 61326: Power Factor Controller.

●●IEC 62208: Empty enclosures for low-voltage switchgear and
controlgear assemblies – General requirements.
