Scope and Applicability
CAN CSA E61347-2-3-03 (2018) is the Canadian adoption of the international standard IEC 61347-2-3 for particular safety requirements of a.c. supplied electronic ballasts for fluorescent lamps. This standard applies to electronic ballasts intended for operation on a.c. supplies up to 1000 V at 50 Hz or 60 Hz, with operating frequencies that may deviate from the supply frequency. It covers ballasts for use in built-in, independent, or integral configurations for indoor or outdoor applications.
The standard focuses on electronic ballasts that are used with preheat, rapid start, or instant start fluorescent lamps. It also includes requirements for ballasts equipped with ignitors integrated within the ballast housing. The 2018 edition introduces updated clauses related to insulation coordination, thermal requirements, and marking to align with contemporary safety practices.
This standard is to be used in conjunction with CAN CSA E61347-1 (the general requirements for lamp controlgear). The particular requirements of this part supplement or modify the corresponding clauses in the general standard.
Tip: Manufacturers should verify that their ballasts comply with both Part 1 and Part 2-3 requirements. Testing to the latest edition ensures market access across Canada.
Technical Requirements
The technical requirements of CAN CSA E61347-2-3-03 (2018) are organized into several key areas including electrical, mechanical, thermal, and marking specifications. Below are the critical technical parameters that must be satisfied for compliance.
Electrical Requirements
- Input Voltage and Frequency: The ballast must operate safely over the rated voltage range (±10% typically) and at rated frequency tolerance (±2%).
- Power Factor: A minimum power factor of 0.5 (or higher for high-power-factor types) is required at rated voltage and full load.
- Supply Current Harmonics: Ballasts must comply with limits set by applicable EMC standards (e.g., IEC 61000-3-2).
- Starting Conditions: The ballast must provide adequate preheat current and ignition voltage as specified by lamp manufacturers.
- Abnormal Conditions: The ballast must be designed to withstand open-circuit, short-circuit, and lamp-end-of-life conditions without creating a safety hazard.
Insulation and Clearances
The standard mandates specific creepage distances and clearances based on working voltage, pollution degree, and material group. Table 1 summarizes the minimum values for insulated parts.
| Working Voltage (V) | Pollution Degree | Minimum Creepage (mm) | Minimum Clearance (mm) |
| ≤ 50 | 1 | 0.5 | 0.5 |
| > 50 and ≤ 150 | 2 | 1.5 | 1.0 |
| > 150 and ≤ 300 | 2 | 3.0 | 2.0 |
| > 300 and ≤ 600 | 3 | 6.0 | 4.0 |
Important: The table values are illustrative. Detailed tables with derating factors for altitude, coatings, and material groups must be consulted in the standard text.
Thermal Requirements
Ballasts must withstand normal and abnormal temperature conditions. The maximum case temperature (tc) is specified by the manufacturer and must not be exceeded under any normal or fault condition. A thermal endurance test (e.g., using a thermocouple) verifies that the winding temperature rise complies with limits (typically ≤ 90 K for class B insulation). Protection against excessive temperature under fault conditions (e.g., blocked cooling) is required.
Marking and Instructions
The ballast must be clearly marked with the following information: manufacturer’s name or trademark, model number, rated supply voltage, frequency, rated lamp power, number of lamps, maximum case temperature (tc), and safety certifications. Markings must be durable and legible.
Implementation Highlights
Designing a ballast to meet CAN CSA E61347-2-3-03 (2018) requires careful attention to several implementation aspects:
- Component Selection: Use of capacitors, inductors, and semi-conductors that are rated for the operating voltage and temperature. Electrolytic capacitors must be selected for long life and ripple current capability.
- PCB Design: Proper layout for high-voltage parts, adequate spacing, and use of insulating varnish or conformal coating where required.
- Ignition Circuit: For rapid-start ballasts, ensure consistent preheat current timing and voltage to avoid lamp flicker or cathode damage.
- Fault Protection: Incorporate protection circuits such as overvoltage clamping, overcurrent shutdown, and overtemperature sensors. These features are often mandatory for compliance with abnormal condition tests.
- Thermal Management: Provide adequate heat sinking and ventilation. The ballast must pass the temperature test under worst-case conditions (e.g., enclosed fixture).
Best Practice: Engage an accredited testing laboratory early in the design process. Pre-compliance testing reduces development time and cost.
Compliance and Certification Notes
In Canada, compliance with CAN CSA E61347-2-3-03 (2018) is typically demonstrated through a certification process to obtain a CSA mark or another recognized mark. The standard is referenced by the Canadian Electrical Code (CE Code) for certain installations.
Key compliance points:
- The standard supersedes previous editions such as CAN CSA E61347-2-3-02. Manufacturers with existing certifications should verify transition deadlines.
- For ballasts with integral ignitors, additional tests per Annex A of the standard apply (ignitor durability).
- Ballasts for emergency lighting may have additional requirements under CSA C22.2 No. 141.
- Differences from IEC 61347-2-3:2011+A1:2016 include Canadian deviations for supply voltage tolerances and temperature test conditions.
Important: Non-compliant ballasts may pose fire and shock hazards. Product liability and market entry in Canada effectively require third-party certification, even if not explicitly mandated by law.
As of 2026, this edition of the standard remains current and is referenced in the CE Code and provincial regulations. Manufacturers are advised to check the CSA Group website for latest editions or amendments.
Finally, below are frequently asked questions regarding this standard.
Q: Is CAN CSA E61347-2-3-03 (2018) identical to IEC 61347-2-3?
A: The standard adopts IEC 61347-2-3 with Canadian deviations. Users must refer to the national preface for specific modifications, such as differences in supply voltage ratings and acceptance criteria for some tests.
Q: Does this standard cover ballasts for LEDs?
A: No. This standard is specifically for fluorescent lamp ballasts. LED drivers are covered under CAN CSA E61347-2-13 or similar standards.
Q: Is third-party certification mandatory?
A: While not federally mandated for all products, many provincial electrical codes and utilities require certification (e.g., CSA mark) for installation. Liability concerns strongly encourage certification.
Q: How often is the standard updated?
A: The standard is periodically amended to align with IEC updates or Canadian requirements. The next revision may be triggered by a new IEC edition or via CSA internal review. Check the CSA store for the latest version.
