IEC 61558 - For Power Transformers, Power Supplies, Reactors, and Similar Products.
AS/NZS IEC EN 61558 is a key safety standard for power transformers, power supplies, reactors, and similar products. This standard ensures that such devices adhere to rigorous safety requirements to protect users from electrical hazards.
These devices are used in a variety of applications, including industrial, commercial, and residential environments. The standard is divided into several parts, each addressing different types of transformers and power supplies, such as safety isolating transformers, control transformers, and general purpose transformer
Key Safety Requirements
The AS/NZS IEC EN 61558 standard specifies several safety requirements to ensure the safe operation of the devices it covers. These requirements include:
- Electrical Insulation: Ensuring adequate insulation to prevent electric shock.
- Temperature Control: Regulating the temperature to avoid overheating and potential fire hazards.
- Mechanical Stability: Ensuring the device can withstand mechanical stresses during normal operation.
- Protection Against Electric Shock: Implementing measures to protect users from electric shock.
- Fire Resistance: Using materials and designs that minimize the risk of fire.

Quick FAQ'S
Power transformers, reactors, power supply units, and similar products intended for general use.
The standard is divided into several parts, each addressing different types of transformers and power supplies, such as general requirements (IEC 61558-1) and particular requirements for specific types of equipment.
It sets requirements for electrical, thermal, and mechanical safety, including insulation, temperature rise, dielectric strength, and protection against overloads.
Insulation is critical for preventing electric shock and ensuring the safe operation of transformers and power supplies under various conditions.
Medical transformers often fall under specific medical standards like IEC 60601, but IEC 61558 can apply if they are not exclusively for medical use.
Manufacturers need to provide detailed documentation including design specifications, test reports, risk assessments, and compliance declarations.
