Safety Testing and Compliance Verification for Switchgear    

The International Electro-technical Commission (IEC) 61439 series of standards provides a frame work to meet the needs of all associated stake-holders in today’s electrical assemblies global supply chain trends (original manufacturer, assembly manufacturer, component manufacturer, installer, specifier and etc.). IEC 61439 series of standards considers a practical approach with multiple design verification options, clearly specifying the safety and performance requirements for reference and use by engineering consultants, manufacturers, planners, system engineers, test lab and end users in order to define the protection objectives for people and plants in electrical installations. This standard has now been widely accepted globally, and member countries have either adopted, or harmonized their national standards with the IEC 61439 series, making it truly internationally accepted certification for assemblies. The IEC 61439 series applies to low-voltage switchgear and control-gear assemblies, for rated voltage up to 1,000V (AC) and 1,500V (DC).

Benefits of UL Type Testing and Certification Services.
• Demonstrates Compliance / Verification to applicable safety standard as required
  by Engineering consultants / specifiers and end users.
• UL Type test certificates (Type Examination Certificate - TEC), Test Reports and UL mark
  certification are well accepted by stakeholders including regulatory organizations,
  manufacturers, specifiers and comes with international recognition.
• Enhances risk and plant safety management for specifiers and Installers.
• Type test flexibility: Specific type tests can be added or updated depending on
   the needs of the specifier / engineering consultant / end user or based on application.
   if additional tests are required later or in case of standards revision in case of UL Selected
   type test programs after UL’s engineering review.

UL mark certification programs to IEC and UL standards consider unique product safety due diligence approach through:
• Detailed product construction review / documentation of product construction,
   ratings, marking and critical components.
• Follow-up verification of products at manufacturer’s facility through un-announced
  inspections for construction compliance to the ones originally evaluated.
• Mitigation of risk of counterfeits via on-line traceability and verification of
   certification at

Who Should Attend

• Government Building/Electrical Officials and Policy Makers
• Engineering Consultants and Practitioners
• Power Switchgear and Control-gear Assembly manufacturers planning
   for ASEAN and Global Market Access
• Operations and maintenance personnel
• Electrical Competent Persons


IEC 61439-1 and IEC 61439-2
This standard applies to all ASSEMBLIES (switchboards and panelboards) whether they are designed, manufactured and verified on a one-off basis or fully standardized and manufactured in quantity.

IEC 61921
This standard applies to low-voltage AC shunt capacitor banks intended to be used for power factor correction purposes, possibly equipped with a built-in switchgear and control-gear apparatus capable of connecting to or disconnecting from the mains part(s) of the bank with the aim to correct its power factor.


Mr. Raghunath Gopalakrishna Rao holds a diploma in Electrical and Electronics Engineering, and an MBA in Marketing and Human Resource Management. Prior to joining UL, he worked for Westinghouse HV Lab, GE Power Controls, Canadian Standard Association (CSA) and Intertek. He was Business and Operation Manager (Asia region) for Intertek for 11 years.

Overall, Mr. Raghunath has 26 years of experience in International Testing and certification, with involvements as:

• Technical advisor for the local utilities (India and Middle East countries).
• NCB Technical reviewer for Low voltage directive and Machinery Directive.
• Approved inspector for various Middle East Authorities with Jurisdiction (AHJs)
   such as ADDC, SEWA, DEWA and SEC.
• 6-sigma Green belt certified holder, and having patent in designing of lighting
   contactor with GE

Mr. Raghunath is currently UL’s Engineering Leader for Middle East, North Africa region, and specializes in LV and MV switchgear and control-gear segments. At UL, he planned and developed state of the art testing facility for low voltage switchgear and control-gear products in Abu Dhabi, UAE. He is also a technical spoke person for the local utilities in UAE, qualified reviewer for the IEC 60947 and IEC 61439 standards, and a motivational speaker for the many OEMS such as ABB and GE.
