When a circuit breaker fails, it’s more than just an inconvenience—it’s a safety hazard. From tripping constantly to failing to cut power during overloads, a faulty breaker puts your property at risk of electrical fires or equipment damage. But how much does circuit breaker replacement cost, and which type do you need? In this guide, we’ll break down prices for common breakers like MCB, MCCB, RCBO, and ACB, compare costs across top brands, and show why CNC Electric’s global lineup of low-voltage products offers 20% savings without sacrificing quality.
Average Circuit Breaker Replacement Costs by Type
Circuit breaker prices vary dramatically based on size, type, and application. Here’s what you can expect to pay for a replacement (including parts only—installation costs vary by electrician):
1. Miniature Circuit Breaker (MCB)
- Use Case: Residential homes, small offices, or retail stores (protects lighting, outlets, and small appliances).
- Current Range: 6A–125A.
- Average Cost: $15–$50 (mainstream brands like Siemens or ABB).
2. Molded Case Circuit Breaker (MCCB)
- Use Case: Commercial buildings, factories, or data centers (handles higher currents for HVAC systems, machinery, or server racks).
- Current Range: 100A–1600A.
- Average Cost: $150–$600 (mainstream brands like Schneider Electric or Eaton).
3. Residual Current Circuit Breaker with Overload Protection (RCBO)
- Use Case: Wet areas (kitchens, bathrooms) or sensitive equipment (medical devices, labs) to prevent electric shock.
- Current Range: 6A–100A.
- Average Cost: $30–$80 (mainstream brands like Legrand or ABB).
4. Automatic Transfer Switch (ATS)
- Use Case: Critical facilities (hospitals, data centers) to switch power from grid to backup generators during outages.
- Current Range: 30A–2500A.
- Average Cost: $500–$2,000+ (mainstream brands like Generac or Cummins).
5. Air Circuit Breaker (ACB)
- Use Case: Industrial plants, power substations, or large manufacturing facilities (manages high-voltage, high-current systems).
- Current Range: 630A–6300A.
- Average Cost: $800–$5,000 (mainstream brands like Siemens or Schneider Electric).
When to Replace Your Circuit Breaker (Signs You Can’t Ignore)
Don’t wait for a fire or outage—replace your breaker if you notice:
- Frequent Tripping: If it trips when you plug in appliances, it’s overloaded or faulty.
- Burning Smell or Heat: A hot breaker or burning odor means internal damage.
- Visible Rust or Damage: Corrosion or cracks compromise safety.
- Outdated Design: Breakers older than 20 years may lack modern safety features (e.g., RCBOs for shock protection).
How to Choose the Right Breaker for Replacement
-
Match the Type to Your Needs:
- Use MCBs for small circuits (lights, outlets).
- Upgrade to RCBOs in wet areas (kitchens, garages).
- For industrial systems, MCCBs or ACBs handle higher currents.
-
Check Current Rating: Never replace a breaker with a higher amp rating than the wiring can handle (e.g., 14-gauge wire = 15A max).
-
Prioritize Certifications: Look for IEC, CE, or UL stamps to ensure safety and compliance.
