BIS certification for semiconductor controllers and contactors for non-motor loads is mandatory as per IS/IEC 60947-4-3. Manufacturers must ensure full compliance with BIS requirements, including product testing, factory inspection, and adherence to ISI marking guidelines.

In modern industrial applications, reliable switching and control of non-motor electrical loads—such as lighting, heating elements, and resistive loads—is essential. To ensure safety, performance, and compliance with global standards, the Bureau of Indian Standards (BIS) has mandated ISI Mark certification for these products under the standard IS/IEC 60947-4-3: Low-Voltage Switchgear and Controlgear – Part 4/Sec 3.

This certification applies specifically to semiconductor controllers and contactors designed for non-motor loads, ensuring they meet strict safety and quality criteria.

What Are Semiconductor Controllers for Non-Motor Loads?

These are solid-state switching devices used in electrical installations where precision control of non-motor loads is required. Typical applications include:

Industrial ovens and heaters

Lighting systems

Power supplies and UPS systems

Automation and control panels

Unlike motor starters, these devices manage electrical loads without rotating machinery, making their usage and stress conditions unique.

Applicable Indian Standard

Standard Name: IS/IEC 60947-4-3

Title: Low-Voltage Switchgear and Controlgear – Part 4: Contactors and Motor-Starters – Section 3: Semiconductor Controllers and Semiconductor Contactors for Non-Motor Loads (Third Revision)

Type: ISI Mark Certification (Mandatory)

Regulating Authority: Bureau of Indian Standards (BIS)

Compliance Mandate: As per Quality Control Order (QCO) issued by the Government of India

Objective of BIS Certification

The purpose of this certification is to:

Ensure safe operation of semiconductor contactors in non-motor applications

Promote uniform quality standards across domestic and imported products

Prevent use of unsafe or substandard components in industrial setups

Align Indian manufacturing with global electrical standards (IEC)

Major Tests as per IS/IEC 60947-4-3

Testing is conducted in BIS-approved laboratories and includes:

Dielectric Strength and Insulation Resistance

Load Switching Capacity and Endurance

Thermal and Short-Circuit Withstand Tests

Functional Performance Tests

EMC (Electromagnetic Compatibility)

Environmental Tests (Temperature, Humidity)

Electrical and Mechanical Endurance Cycles

BIS Certification Process

The process for obtaining the BIS license under Scheme I – ISI Mark Scheme is as follows:

Online Application via the Manakonline Portal

Document Submission including technical specifications, layout, manufacturing process, etc.

Product Testing in BIS-recognized laboratories

Factory Audit by BIS officials

Grant of License upon successful compliance

Marking Authorization to use the ISI mark

Documents Required

Company Registration and Factory License

Manufacturing Flowchart and Process Details

In-house Testing Capabilities and Equipment List

Technical Data Sheets of the Products

Packaging and ISI Marking Samples

Undertaking of Compliance and Safety

Test Reports (if applicable)

Power of Attorney (for foreign manufacturers)

For Foreign Manufacturers

Overseas entities can apply through the Foreign Manufacturers Certification Scheme (FMCS). An Authorized Indian Representative (AIR) must be appointed to act as a liaison between the manufacturer and BIS.
