The Low-Voltage Switchgear and Controlgear – Part 4: Contactors and Motor-Starters – Section 3: Semiconductor Controllers and Semiconductor Contactors for Non-Motor Loads (3rd Revision) is a landmark in terms of regulations and is a major step towards India’s changing electrical safety paradigm. The revised standard, issued in conformity with global standards, deepens the technical stipulations concerning the semiconductor-based control devices in the non-motor application area.
As a consultant for UMSPCS compliance, we are very much involved with producers and distributors in terms of compatibility with the latest BIS Certification Quality Control Orders (QCOs) and Indian Standards.
Understanding the Scope of Section 3 (3rd Revision)
This standard is binding only on semiconductor controllers and semiconductor contactors that are intended for non-motor loads, e.g.,
- Electrical heating equipment
- Lighting circuits
- Power resistors and capacitive loads
- Industrial non-motor switching applications
While the motor starters regulated in other parts of IS/IEC 60947-4 are not included in this section, it is about electronic switching devices in which amperage is controlled by semiconductors rather than mechanical contacts.
What’s New in the 3rd Revision?
The 3rd Revision brings into focus technical details more clearly and sets tougher performance standards, among other things:
- Semiconductor controllers: revised definitions and reclassification
- Enhanced thermal performance and endurance test criteria
- Enhanced safety measures against overcurrent, short-circuit, and abnormal operating conditions
- Conformity with the latest IEC requirements for worldwide compatibility
These modifications guarantee increased product dependability, lower risk of failure, and better safety of the device in operation, that is to say, in industrial and commercial installations, where non-motor loads are of prime importance.
BIS QCO Impact and Mandatory Compliance
As the BIS QCO requirements for low-voltage switchgear and controlgear are becoming more stringent, products falling under this category might be required to have a mandatory BIS certification for electronic product before they are allowed to be manufactured, sold or imported in India.
Manufacturers from India and abroad will have to comply with the correct conformity assessment procedures, which might involve:
- product testing at laboratories recognized by BIS
- factory inspection and quality process verification;
- certification under the BIS Scheme or FMCS (Foreign Manufacturers Certification Scheme) for overseas entities.
Non-compliance with the standard and QCO requirements can expose the offender to penalties, supply chain delays, or being barred from the market.
Why Compliance Matters for Industry
Semiconductor contactors for non-motor loads are typically found in automated systems, HVAC units, power distribution panels, and lighting control systems. Products that do not meet the standards expose the users to the risk of overheating, electrical fires, early equipment failure, and consequences from the authorities.
Adhering to the Low-Voltage Switchgear and Controlgear Part 4 Section 3 (3rd Revision) standard guarantees:
- improved safety and performance of the product
- Compliant market access in India
- Increased customer trust and loyalty
- Conformity with worldwide electrical standards

BIS Certification Process for Low-Voltage Switchgear & Controlgear
Part 4 Section 3: Semiconductor Controllers & Contactors for Non-Motor Loads (3rd Revision)
In order to comply with Part 4 Section 3 (3rd Revision) of Low-Voltage Switchgear and Controlgear, it is mandatory for manufacturers and importers who deal with semiconductor controllers and semiconductor contactors for non-motor loads. According to the applicable BIS Quality Control Orders (QCOs), products have to be certified if they are going to be placed on the Indian market.
Being a UMSPCS compliance consultant, we involve clients in the BIS certification process that runs through each stage, thereby ensuring not only the correctness and speed but also the confidence in respect of the regulations.
Step 1: Product Applicability Assessment
The very first and most important step is to find out if your product is covered by Part 4 Section 3. UMSPCS assesses:
- Product type and function
- Whether the semiconductor controller or contactor is used for non-motor loads
- Voltage and current ratings
- End-use applications (lighting, heating, power control, etc.)
This is the step where misclassification is avoided, which is a frequent reason for application rejection or slowdowns.
Step 2: Standard Identification & Compliance Mapping
After the applicability is confirmed, UMSPCS locates the precise Indian Standard conforming to IS/IEC 60947-4 Section 3 (3rd Revision).
Mapping is done by us:
- technical requirements
- safety and performance parameters
- testing clauses and documentation needs
It is an assurance that your product design and specifications are in complete harmony with the requirements of BIS even before the testing phase.
Step 3: Document Preparation
Documentation that is accurate is the main factor that leads to BIS approval. UMSPCS supports in making and checking:
- Product technical datasheets
- Circuit diagrams and control schematics
- Bill of materials (BOM)
- Quality control and manufacturing process documents
- Factory layout and equipment details
For foreign manufacturers, documentation is prepared in accordance with the requirements of the FMCS (Foreign Manufacturers Certification Scheme).
Step 4: Product Testing in BIS-Recognized Laboratory
Samples are sent to a laboratory recognized by BIS for testing according to the 3rd Revision standard. Testing usually involves:
- Electrical performance and endurance tests
- Thermal and overload behaviour
- Short-circuit and abnormal condition tests
- Safety and insulation verification
UMSPCS deals with laboratory bookings, sample logistics, and test report follow-ups to save time.
Step 5: BIS Application Submission
The BIS application is submitted through the BIS portal under the relevant certification scheme after the testing is successful. UMSPCS takes care of:
- Online application filing
- Upload of test reports and documents
- Communication with BIS officers
This step is very important. If there is any inconsistency, it may result in questioning or denial.
Step 6: Factory Inspection & Audit
BIS factory inspections may be aimed at verifying:
- Manufacturing process consistency
- In-house testing facilities
- Quality assurance systems
- Traceability and marking procedures
UMSPCS gets manufacturers ready for inspections by conducting mock audits and performing compliance checks.
Step 7: License Grant & Marking Approval
After a successful review, BIS issues a license to use the mark on products according to the requirements set by law. The manufacturers or importers are legally allowed to:
- Manufacture
- Import
- Sell in the Indian market
UMSPCS also provides clients with the necessary information to ensure proper marking and labelling compliance.
