Residual Current Operated Circuit-Breakers with Integral Overcurrent Protection (RCBOs) are designed to protect against circuit overloads. In case of current leakage, the circuit breakers switch off the power automatically. They are mostly found in residential and commercial buildings. Such circuit breakers are most appropriate in order to avoid electrical dangers. BIS certification ensures that RCBOs meet strict safety, performance, and reliability requirements.
According to IS 12640 (Part 2): 2016, all specifications related to the construction and testing of RCBOs are provided so that the equipment can be used safely. Manufacturers must ensure compliance through rigorous testing for tripping characteristics, insulation strength, and fault performance. This ensures consistent operation under real-world conditions. Circuit breaker manufacturers must obtain a BIS license to sell the products to Indian customers.
What is IS 12640 (Part 2): 2016?
This is the Indian Standard for Residual Current Operated Circuit-Breakers with Integral Overcurrent Protection used in household appliances. It mentions the criteria to ensure protection against electric shock and overload. As per the BIS (Bureau of Indian Standards), RCBOs are:
- Assessed for insulation resistance
- Verified for electrical endurance
- Checked for short-circuit protection
- Evaluated for safe operation
Eligibility for Overcurrent Protection Device BIS License
BIS authorisation under IS 12640 (Part 2): 2016 is required for businesses involved in manufacturing, importing, or supplying RCBOs for households in India.
Applicable to:
- Manufacturers (India) - Must get BIS approval if the products are covered under QCO.
- Foreign Manufacturers - Need certification to export Circuit Breakers to India.
- Importers/Brand Owners - Must ensure that the products are BIS-certified before sale.
- Sellers/Distributors - Should only sell certified electrical safety devices.
Testing and Inspection Requirements
To ensure the electrical safety of households, the Bureau of Indian Standards outlines the minimum requirements under IS 12640 (Part 2): 2016. This certification ensures that manufacturers meet the safety standards for RCBOs used in residential and similar applications. The BIS testing parameters and quality checks for the circuit breakers are listed below:
| Test Group | What is Tested | Purpose |

| Component Reliability Tests | Screws, terminals, and current-carrying connections | Ensures secure electrical and mechanical connections |
| Protection Against Electric Shock Tests | Safety under direct and indirect contact conditions | Ensures user protection from electrical hazards |
| Electrical Endurance Tests | Repeated switching and operational cycles | Ensures long-term durability and operational reliability |
Steps to get BIS Approval for Electrical Circuit Breakers
The BIS Authorisation process ensures that the Residual Current Circuit Breaker meets the required standards for proper and efficient operation. This process is set by the Bureau of Indian Standards (BIS) and includes the following steps:
- Online Registration: Manufacturers register on the BIS Manak portal by submitting company, factory, and product details. Foreign manufacturers must appoint an Authorized Indian Representative (AIR).
- Testing at BIS-Approved Laboratory: Product samples are tested in BIS-approved laboratories for tripping characteristics, electric strength, insulation resistance, mechanical endurance, and short-circuit performance.
- Application Submission: The application is submitted along with test reports, technical documents, and factory details. Foreign manufacturers must also submit AIR-related documents.
- Factory Inspection: Officials from the Bureau of Indian Standards inspect the manufacturing units to verify the production process, safety measures, and quality control system.
- Grant of BIS License: Upon successful verification of all requirements, BIS grants the certification license under Scheme-I.
- Use of ISI Mark: Once approved, the manufacturer is permitted to use the ISI mark on the product with a CM/L number, confirming that the product meets BIS standards.
