Overview

The IEC 60947-6-2:1992/AMD2:1998 amendment pertains to the international standard for low-voltage switchgear and controlgear, specifically Part 6-2 which covers multiple function equipment. This amendment revises and updates the section on Control and Protective Switching Devices (CPS). The standard is developed by the International Electrotechnical Commission (IEC), under the technical subcommittee 17B focusing on low-voltage switchgear and controlgear.

The amendment clarifies the operational and testing requirements for CPS devices, emphasizing their capability to provide both control and protective functions for electrical circuits. Notably, these devices are designed to be operated by means other than manual intervention, often remotely or via external energy sources, enhancing automation and safety in electrical installations.

Key Topics

  • Definition and Operation
    CPS devices are described as capable of being operated by non-manual means, aided or unaided by local manual controls. This ensures flexibility in how controlgear can be managed, providing remote or automated operation capabilities.

  • Protection Functions
    These devices combine overload and short-circuit protection. The functions are coordinated to ensure continuity of service under all current conditions up to their rated breaking capacity (Ics), defining their robustness and reliability in fault situations.

  • Manufacturer Responsibilities
    The amendment defines the manufacturer’s role as the party responsible for verifying compliance with this standard and providing necessary product information, including marking, identification, and technical characteristics.

  • Testing and Performance Requirements
    The amendment introduces detailed test sequences and operational performance criteria, including:

    • Tests at rated voltage/current and short-circuit capacities.
    • Procedures for dielectric withstand verification.
    • Overload release function testing.
    • Defined sequences for operational performance before and after short-circuit tests at rated and “r” (conventional test) currents.
  • Short-Circuit Current Ratings
    Updated tables specify the values for prospective conventional test currents (Icr and Ir currents) based on the type and rated current of the device, assuring standardized testing conditions across manufacturers.

  • Operational Sequences
    Amendments to test sequence III outline specific steps for verifying device operation under load and fault conditions, guaranteeing performance and durability in real-world applications.

Applications

  • Industrial and Commercial Electrical Panels
    CPS devices designed according to IEC 60947-6-2:1992/AMD2:1998 are essential components within low-voltage switchgear assemblies used for protecting and controlling power distribution circuits in factories, commercial buildings, and infrastructure projects.

  • Automated Control Systems
    By enabling operation through external energy sources rather than manual handling, these devices are integral to automated and remote control systems, improving responsiveness and safety while reducing manual labor.

  • Continuity of Service
    The coordinated protection features ensure minimal downtime during electrical faults such as overloads and short circuits, making them suitable for critical electrical networks requiring high reliability and service continuity.

  • Safety Compliance and Certification
    Compliance with this amendment assures manufacturers and users alike that the CPS devices meet rigorous international safety and performance requirements, facilitating global market acceptance.

Related Standards

  • IEC 60947-1
    General rules for low-voltage switchgear and controlgear, including definitions, common technical requirements, and testing methods. The amendment references power-factor and time-constant parameters from this standard.

  • IEC 60947-6-1
    Specifies requirements for multiple-function equipment other than CPS, including switching devices coordinated for control and protection.

  • Other IEC Switchgear Standards
    Standards addressing auxiliary devices, low-voltage circuit breakers, and overload relays that complement the CPS functionalities.
