RCBO Breakers – Leading OEM/ODM Manufacturer
Need reliable RCBO breakers but standard models don’t fit your market requirements? Sourcing a compliant, high-quality custom breaker from a trusted partner is complex. We manufacture certified RCBO breakers and provide full OEM/ODM services, from custom branding to new product development.
An RCBO (Residual Current Breaker with Overcurrent Protection) is a vital safety device. It combines the functions of an RCCB (earth fault protection) and an MCB (overload/short-circuit protection) in one compact unit. We specialize in manufacturing and customizing these devices to global standards for B2B clients.Explore our complete range of certified RCBO products below, or learn how our custom OEM/ODM solutions can meet your specific project requirements.
Cooperation with Global Brands
We have established partnerships with well-known global brands.

RCBO Breakers Applications & Technical Resources
Understanding RCBO types is critical for compliance and safety, especially with the rise of electronic equipment. Different types are designed to detect different electrical fault “waveforms”.
RCBO Breakers Type Selection Guide
Detects standard AC sinusoidal residual currents.
Suitable for pure AC loads (Resistive Loads).
* Water Heaters
* Incandescent Lighting
* Electric Ovens
Detects AC and pulsating DC residual currents.
Applicable to Class 1 electronic devices.
* Personal computers (PCs)
* LED lighting drivers
* Household appliances (such as washing machines and dishwashers)
High immunity to nuisance trips. Detects mixed-frequency currents.
Suitable for equipment with inverters.
* Modern Air Conditioners
* Heat Pumps
* Variable Speed Tools
Detects AC, pulsating DC, and smooth DC residual currents.
Suitable for complex industrial and commercial equipment.
* Solar/PV Inverters
* Electric Vehicle Charging Stations
* Three-Phase VFDs
RCBO Sensitivity Selection Guide
High-risk wet areas.
* Bathroom sockets
* Medical equipment
Standard choice to prevent electric shock.
* All Sockets (Residential and Commercial)
* Portable Equipment
Suitable for circuits with low risk of personal contact.
* Fixed Equipment
* Sub-distribution
For protection of equipment from the risk of fire due to high leakage current only.

Frequently Asked Questions about RCBO Breakers
Do you have technical, sourcing, or customization questions about RCBOs? Finding clear, reliable answers specific to B2B and OEM/ODM procurement is difficult. We have compiled the 8 most common questions our partners ask to help you source with confidence.
A1: An RCBO (Residual Current Breaker with Overcurrent Protection) is an all-in-one device. It provides 3 types of protection: earth fault (leakage), overload, and short-circuit. An RCCB (Residual Current Circuit Breaker) only provides earth fault protection. It must be paired with an MCB (Miniature Circuit Breaker) to protect against overloads and short circuits.
A2: This is critical for modern electronics. Type AC is designed for standard AC sinusoidal currents (e.g., heaters, incandescent lights). Type A is required for modern loads. It detects both standard AC and pulsating DC fault currents, which are common in electronic devices like PCs, inverters, and LED drivers.
A3: 1P+N stands for "One Pole + Neutral". It is a compact, two-module wide RCBO common in single-phase distribution boards. It provides overcurrent protection on the single phase (live) wire and switches both the phase and neutral wires during a fault, ensuring full isolation of the circuit.
A4: Quality and compliance are our priority. Our RCBO breakers are manufactured to meet major international standards. We hold certifications including CE (Europe), CB (International), TÜV, and SAA (Australia). We can also collaborate with you to secure specific regional certifications for large-scale ODM projects.
A5: Our MOQ is flexible and depends on the project's complexity.
OEM (Your Brand): Simple logo printing and custom packaging have a lower MOQ.
ODM (New Design): Projects requiring new R&D or custom molds will have a higher MOQ.
Please contact our team directly for a specific quote based on your requirements.
6: Lead times vary based on the product type and order volume. Standard products are typically ready within 7-20 days. Custom OEM/ODM orders may take 20-30 days after prototype approval. We provide a precise schedule upon confirmation of your order details.
A7: Yes. This is our core strength. If you have specific technical requirements (e.g., unique size, different tripping characteristics, or special certification needs), our R&D and engineering teams will work with you from concept and design to prototyping, testing, and mass production.
A8: We follow a strict ISO 9001-certified quality control process. Every RCBO undergoes 100% testing on the production line, including calibration of its tripping mechanism (both thermal/magnetic) and its residual current sensitivity. We maintain full traceability of components and test results.
