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.

Introduction

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?

Semiconductor controllers for non-motor loads are solid-state devices used to control and regulate electrical loads that do not involve rotating machinery. They are commonly used in industrial heaters, ovens, lighting systems, power supplies, UPS systems, and automation panels. Unlike motor controllers, these devices are designed specifically for non-motor applications and operate under different load and stress conditions.

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
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 with 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:

1. Dielectric Strength and Insulation Resistance

2. Load Switching Capacity and Endurance

3. Thermal and Short-Circuit Withstand Tests

4. Functional Performance Tests

5. EMC (Electromagnetic Compatibility)

6. Environmental Tests (Temperature, Humidity)

7. Electrical and Mechanical Endurance Cycles

BIS Certification Process

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

1. Online Application via the Manakonline Portal

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

3. Product Testing in BIS-recognized laboratories

4. Factory Audit by BIS officials

5. Grant of License upon successful compliance

6. Marking Authorization to use the ISI mark

Documents Required

1. Company Registration and Factory License

2. Manufacturing Flowchart and Process Details

3. In-house Testing Capabilities and Equipment List

4. Technical Data Sheets of the Products

5. Packaging and ISI Marking Samples

6. Undertaking of Compliance and Safety

7. Test Reports (if applicable)

8. 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.
