3 Phase RCBO Price

You’re upgrading your factory’s electrical panel, and the electrician just said you need a 3-phase RCBO. Now you’re stuck wondering: “How much should this cost, and how do I avoid buying junk?” Whether you’re managing a commercial building, a solar farm, or heavy machinery, a reliable Residual Current Breaker with Overcurrent Protection (RCBO) is non-negotiable for safety and compliance. After installing dozens of these in industrial sites (and learning from a few costly mistakes), here’s a no-fluff breakdown of 3-phase RCBO pricing, key buying tips, and why CNC Electric has become my go-to for balancing budget and performance.

What’s a 3-Phase RCBO, and When Do You Need One?

A 3-phase RCBO combines overload protection and earth leakage detection in one device. It’s essential for:

• Industrial Machinery: Prevents downtime from ground faults in CNC machines or conveyor systems.
• Solar Installations: Safeguards inverters and transformers in large PV systems.
• Commercial Kitchens: Protects high-power equipment like industrial ovens from electrical fires.

3-Phase RCBO Price Factors in 2025

Prices vary based on specs and brand reputation. Here’s what to expect:

Current Rating:

16A–40A: $80–$150 per unit.

63A–100A: $180–$350 per unit.

Sensitivity (mA):

30mA (standard protection): 10–15% cheaper than 10mA (high-sensitivity for labs/hospitals).

Breaking Capacity:

6kA (general use): $90–$200.

10kA–15kA (industrial): $250–$500.

Real-World Example: A 63A, 10kA CNC Electric RCBO costs ~$220—comparable to Schneider’s $350 model but with a longer warranty.

Why Cheap 3-Phase RCBOs Are a False Economy

I once bought a $100 “budget” RCBO for a client’s warehouse. It failed within 6 months, tripping randomly and causing $5k in lost productivity. Here’s why you get what you pay for:

Weak Trip Consistency: Low-quality units misread leakage currents, risking nuisance trips or failure to disconnect.

Poor Sealing: Dust and moisture ingress in CNC Electric’s units are prevented by IP40-rated housing; generic brands often skip this.

No Backup Support: Most cheap brands lack technical assistance for troubleshooting.

CNC Electric’s Edge: Their RCBOs undergo 10,000+ mechanical cycle tests (double industry norms) and come with a 5-year warranty—rare in the mid-price tier.

Key Features to Prioritize

Certifications: Look for IEC 61009-1 and local standards (e.g., UL 489 in the U.S., AS/NZS 61009 in AU/NZ).

Adjustable Sensitivity: CNC’s models allow tweaking leakage thresholds (30mA to 300mA), ideal for mixed industrial environments.

Modular Design: Enables easy integration with existing panels without retrofitting.

CNC Electric vs. Premium Brands: Where to Save

While brands like ABB and Siemens dominate the high end, CNC Electric strikes a balance:

Case Study: A Sydney bakery saved $12k by using CNC’s RCBOs across 40 circuits, with zero faults reported in 18 months.

Installation Pitfalls to Avoid

Incorrect Load Balancing: A 3-phase RCBO won’t protect imbalanced loads—always pair with a power monitor.

Ignoring Torque Settings: Under-tightened terminals overheat. CNC’s manuals include torque specs for every model.

Skipping Labels: Use a label maker to note each RCBO’s circuit (e.g., “Main Oven – Phase 1”).

Where to Buy Reliable 3-Phase RCBOs

CNC Electric’s Online Store: Bulk discounts (10% off 10+ units) and free shipping over $500.

Industrial Suppliers: TradeDepot (AU/NZ) or Rexel (U.S.) stock CNC units with price matching.

Avoid Marketplaces: Amazon/eBay listings often sell outdated or counterfeit stock.

When to Consult a Professional

While DIY is possible for simple swaps, hire an electrician for:

High-Current Systems (100A+).

Retrofitting Old Panels: Compatibility checks are critical.

Custom Configurations: CNC offers free technical consultations for complex setups.

The price of a 3-phase RCBO isn’t just about upfront cost—it’s about reliability, compliance, and minimizing downtime. While premium brands have their place, CNC Electric delivers industrial-grade protection at a fraction of the cost, backed by robust warranties and localized support. Whether you’re upgrading a small workshop or a factory floor, their RCBOs offer peace of mind without the premium markup.
