Choosing between an RCCB (Residual Current Circuit Breaker) and an RCBO (Residual Current Circuit Breaker with Overcurrent Protection) is crucial for electrical safety in homes, offices, and industrial facilities. While both devices protect against electric shocks and faults, their functionalities and costs differ significantly. In this guide, we’ll compare RCCB and RCBO prices, explain their applications, and highlight why CNC delivers certified, cost-effective solutions for modern electrical systems.
RCCB vs RCBO: What’s the Difference?
RCCB (Residual Current Breaker)
Function: Detects residual current (earth leakage) and trips to prevent electric shocks.
Protection Scope: Only guards against earth faults, not overloads/short circuits.
Installation: Requires pairing with an MCB (Miniature Circuit Breaker) for overcurrent protection.
RCBO (Residual Current Breaker with Overcurrent Protection)
Function: Combines earth leakage detection and overcurrent/short-circuit protection in one device.
Protection Scope: All-in-one solution for leakage, overloads, and short circuits.
Installation: Replaces MCB + RCCB setups, saving panel space.
RCCB vs RCBO Price Comparison
| Type | RCCB Price Range | RCBO Price Range |
|---|---|---|
| Budget Brands | $15–$30 | $25–$50 |
| Mid-Tier Brands | $30–$60 | $50–$100 |
| Premium Brands | $60–$150+ | $100–$250+ |
Prices vary based on current rating, poles (1P, 2P, 3P), and certifications. Below are typical price ranges for residential-grade devices (25–63A):
CNC Pricing: CNC’s RCCB and RCBO units are priced 20–30% below premium brands, offering certified quality at mid-tier rates.
Why Choose CNC RCCB/RCBO Solutions?
CNC balances affordability with rigorous safety standards, making it a top choice for residential and commercial projects:
1. Cost Efficiency
RCCB: CNC’s 2P 40A RCCB costs significantly less than Schneider or Siemens equivalents.
RCBO: CNC’s all-in-one RCBO eliminates the need for separate MCBs, cutting installation costs by 40%.
2. Certified Safety
IEC/EN 61009 Compliance: Ensures reliable protection against earth leakage and overcurrents.
10kA Breaking Capacity: Handles high fault currents in industrial environments.
3. Durability
Fire-Resistant Housing: Thermoplastic material withstands heat and corrosion.
10,000 Mechanical Operations: Tested for long-term reliability.
4. Easy Installation
Compact Design: Saves space in electrical panels.
Clear Indicators: Visual trip alerts simplify troubleshooting.
Applications of CNC RCCB/RCBO
Residential Panels: Use RCBOs for kitchens, bathrooms, and outdoor circuits prone to moisture.
Commercial Buildings: Protect office HVAC systems and server rooms with CNC’s 63A RCBOs.
Industrial Facilities: Pair CNC RCCBs with MCCBs (Molded Case Circuit Breakers) for motor protection.
When to Choose RCCB vs RCBO
| Scenario | Choose RCCB | Choose RCBO |
|---|---|---|
| Retrofit Projects | Existing MCBs can be reused | Ideal for new installations |
| Budget Constraints | Lower upfront cost | Higher upfront but long-term savings |
| Space-Limited Panels | Requires extra MCB space | Saves space with all-in-one design |
| High-Risk Areas | Bathrooms, pools, workshops | Critical circuits needing dual protection |
Cost-Saving Tips
Prioritize Critical Circuits: Use RCBOs only for high-risk areas (e.g., wet rooms) and RCCBs elsewhere.
Bulk Purchases: CNC offers discounts for large orders on RCBOs and RCCBs.
Prevent Nuisance Tripping: Ensure proper load calculations to avoid undersizing.
Why Avoid Cheap RCCB/RCBO Units?
False Tripping: Low-quality sensors misfire, disrupting power.
Delayed Response: Fails to detect faults promptly, risking fires or shocks.
Short Lifespan: Poor contacts degrade within 1–2 years.
While RCBOs offer comprehensive protection at a higher price, RCCBs remain a budget-friendly option for simpler systems. CNC bridges the gap by delivering certified RCCB and RCBO units that meet global safety standards without premium branding costs. Whether you’re upgrading a home panel or securing a factory, CNC ensures reliable, affordable circuit protection.
