HOW TO CHOOSE THE RIGHT RCCB
Choose the Correct Pole Configuration
For a single-phase two-wire system, choose a 2P RCCB to disconnect both the live and neutral conductors. For a three-phase four-wire system, choose a 4P RCCB to disconnect all three phase conductors and the neutral conductor.
Typical selection:
- 2P RCCB: Residential buildings, apartments, shops and single-phase distribution boards
- 4P RCCB: Commercial buildings, industrial panels and three-phase distribution systems
Select the Appropriate Rated Current
The rated current of the RCCB should be equal to or higher than the maximum normal operating current of the circuit. Common rated currents include 16A, 25A, 40A, 63A, 80A and 100A.
The rated current must also be coordinated with the upstream MCB, MCCB or fuse. The upstream protective device should prevent the RCCB from being damaged by overload or short-circuit current.
Example:
For a circuit protected by a 40A MCB, a 40A or 63A RCCB may be selected according to the system design and manufacturer requirements.
Choose the Correct Residual Current Sensitivity
The rated residual operating current determines how sensitive the RCCB is to leakage current. The correct value should be selected according to the required protection purpose.
- 30mA: Commonly used for additional protection against electric shock in residential and final circuits
- 100mA: Suitable for equipment protection or higher-level distribution circuits
- 300mA: Commonly used to reduce electrical fire risks in main or distribution circuits
A lower residual current value provides more sensitive protection, but improper selection may increase nuisance tripping.
Choose Type AC or Type A
Type AC RCCBs detect sinusoidal alternating residual currents and are suitable for simple conventional AC loads. Type A RCCBs detect both sinusoidal AC residual currents and pulsating DC residual currents.
Type AC is commonly used for:
- Electric heaters
- Basic lighting circuits
- Conventional resistive loads
Type A is more suitable for:
- Washing machines
- Air conditioners
- Electronic power supplies
- Frequency-controlled equipment
- Household appliances containing electronic circuits
For modern residential and commercial systems with electronic equipment, Type A is generally a more comprehensive choice.

RELIABLE RCCB PROTECTION FOR SAFER POWER DISTRIBUTION
What is the difference between MCB, RCCB, and RCBO?
These three devices serve different protective functions in an electrical system. Here is a quick breakdown to help you choose:
- MCB (Miniature Circuit Breaker): Protects equipment from Overload and Short Circuits. It does not protect against earth leakage or electric shock.
- RCCB (Residual Current Circuit Breaker): Protects humans from Electric Shock and Earth Leakage. It does not protect against overloads or short circuits (it must be paired with an MCB).
- RCBO (Residual Current Breaker with Overcurrent): An all-in-one device that combines the functions of both MCB and RCCB. It protects against Overload + Short Circuit + Earth Leakage.
| Device | Overload Protection | Short Circuit Protection | Earth Leakage Protection | Primary Protection Target |
| MCB (Miniature Circuit Breaker) | YES | YES | NO | Cable & Equipment |
| RCCB (Residual Current Circuit Breaker) | NO | NO | YES | Human Life & Fire Safety |
| RCBO (Residual Current Breaker with Overcurrent) | YES | YES | YES | Complete System & Human Life |

RCCB FAQ: Everything You Need to Know
What is an RCCB and how does it work?
An RCCB (Residual Current Circuit Breaker) is a vital safety device designed to protect people from dangerous electrical shocks and prevent electrical fires. It constantly monitors the balance of current between the phase (live) and neutral wires. If an imbalance is detected—such as when current leaks to the earth because a person touches a live wire or due to damaged wiring—the RCCB trips and cuts off the power in milliseconds.
Does an RCCB require a neutral connection to operate safely?
Yes, for both 2P and 4P RCCBs, the neutral wire must be connected. The RCCB detects leakage currents by comparing the current flowing through the phase(s) and the neutral. Without a proper neutral connection, the internal sensing circuit cannot function correctly, and the test button will not work.
What is the difference between a 2-Pole (2P) and a 4-Pole (4P) RCCB?
A 2P RCCB is designed for single-phase circuits (Phase + Neutral) and is typically used in residential and light commercial settings. A 4P RCCB is designed for three-phase four-wire systems (Three Phases + Neutral) and is standard in industrial, commercial, and large solar PV installations.
