Why Choose TIMELEC as Your RCBO Manufacturer?
Partner with trusted RCBO manufacturers and suppliers to obtain reliable residual current circuit breakers conforming to the IEC 61009-1 standard, featuring overcurrent protection and equipped with ELE/ELM mechanisms and AC/A/F/B type options for various markets.
Higher Safety
The function of RCBO is to provide precise and rapid protection against three core risks in low-voltage power distribution: electric shock (leakage), overheating (overload), and instantaneous high current (short circuit) through an integrated device. Suitable for AC 50Hz circuits with rated voltage up to 240V and rated current up to 40A, used for detecting AC leakage current and pulsating DC leakage current.Faster Fault Finding
The RCBO combines the functions of a miniature circuit breaker and a residual current device. It contains an internal zero-sequence current transformer that provides independent circuit protection by passing through both the live and neutral wires.A More Compact Distribution Board
A single RCBO combines the functions of an MCB and an RCD, helping create a more compact and organized distribution-board layout.Lower Overall Installation Cost
By integrating earth-leakage, overload, and short-circuit protection, RCBOs can reduce the number of separate RCDs/RCCBs, MCBs, and connection accessories required, while simplifying wiring and installation.RCBO Technical Data

RCBO Full Form: Residual Current Operated Circuit Breaker
RCBOs combine residual current protection and overcurrent protection in one DIN-rail device for modern low-voltage distribution systems.
What is an RCBO?
An RCBO combines the functions of a residual current device (RCD) and a miniature circuit breaker (MCB). This dual functionality provides comprehensive protection against both earth leakage and overcurrent faults in a single compact module.
TIMELEC RCBOs are engineered for IEC 61009-1 compliance with ELE/ELM mechanisms and Type AC / A / F / B options for different markets.
How does an RCBO work?
The device uses a zero-sequence current transformer to compare live and neutral currents. When an imbalance caused by leakage is detected, the RCBO trips quickly to reduce electric shock risk.
At the same time, built-in overcurrent protection responds to overloads and short circuits, helping prevent overheating and fire hazards in distribution circuits.
RCBO vs. RCCB: Feature Comparison
| Feature | RCBO | RCCB |
|---|---|---|
| Residual current protection | Yes | Yes |
| Overcurrent protection | Yes | No |
| Device type | Single compact unit | Requires separate MCB |
| Applications | Individual circuits (lighting, sockets, appliances) | Broader circuit groups in distribution boards |
| Installation benefit | More compact panel layout | Lower unit cost, more components needed |
RCBO Manufacturer FAQ
Common questions about TIMELEC residual current breakers with overcurrent protection.
What is an RCBO used for?
Suitable for AC 50Hz circuits with rated voltage up to 240V and rated current up to 40A, used for detecting AC leakage current and pulsating DC leakage current.
What do 30mA, 100mA and 300mA RCBO ratings mean?
Because each RCBO provides independent circuit protection, it does not affect other circuits and can be selected for different protection levels:
- 30mA: Protection against electric shock (residential, office, school, etc.)
- 100mA: Equipment protection, fire protection
- 300mA: Line fire protection, industrial power distribution systems
Which standard do TIMELEC RCBO products comply with?
TIMELEC RCBO devices are designed in accordance with IEC 61009-1 and are available with CB, CE, S and UKCA certification support for export markets.
What is the difference between Type AC, A, F and B RCBO?
RCBO types relate to the waveform and frequency of residual fault current. Type AC, A, F and B options are selected according to national standards and load characteristics in different countries and applications.
Which is better, RCBO or MCB?
An RCBO provides both overcurrent and earth-leakage protection in one device. If only an MCB is used, a separate RCCB is required for leakage protection. RCBOs also isolate only the affected circuit, keeping other circuits energized.
Do you offer OEM / ODM as an RCBO manufacturer?
Yes. TIMELEC supports OEM/ODM customization for RCBO products, including ratings, Type AC/A/F/B options, packaging and private-label branding for distributors and panel builders.
