Circuit breaker prices range from under $10 for a standard residential single-pole to over $50,000 for a large low-voltage power breaker. What you actually pay depends on ampere rating, voltage class, frame type, and — critically — which distributors you compare. This guide breaks it down.
| Breaker Type | Typical Range (Part Only) | Where Used |
|---|---|---|
| Residential MCB (1P, 15–30A) | $8 – $30 | Home panels, QO, BR, QP series |
| Commercial MCB (3P, up to 100A) | $30 – $150 | Small commercial panels |
| MCCB 100–250AF (3P) | $150 – $800 | Industrial distribution, MCC |
| MCCB 400–800AF (3P) | $800 – $4,000 | Feeders, main branch |
| MCCB 1200–2500AF (3P) | $3,000 – $15,000 | Main distribution, substations |
| Low-voltage power breaker (1000A–6000A) | $8,000 – $60,000+ | Main switchgear, draw-out |
| GFCI / AFCI specialty breaker | $30 – $120 | Residential/code-required circuits |
This is the single biggest cost driver. A 20A MCCB and a 1200A MCCB in the same frame family can differ in price by 10x or more. Higher ampere ratings require larger contact surfaces, heavier-duty trip mechanisms, and more robust construction.
Standard MCCBs are often rated 18kAIC or 25kAIC. High-interrupting variants (65kAIC, 100kAIC, 200kAIC) can cost 40–80% more than their standard-AIC equivalents in the same frame. If your system requires high AIC, budget accordingly.
Replacing a thermal-magnetic trip unit with an electronic (ETU) version adds $200–$2,000 to the cost depending on frame size and features. ETUs with communications (Modbus, profibus) carry a premium, but offer significant value in monitored systems.
Shunt trips, auxiliary contacts, undervoltage releases, and lockout handles are all add-ons that can add $50–$500 each to the total cost. When ordering a replacement, document all accessories on the existing breaker — they're often forgotten until the new one arrives without them.
Discontinued breakers often trade at a significant premium on the surplus market — or can't be found at all from a single source. A Square D I-Line breaker that listed at $400 new might now cost $600–$900 surplus, and only a handful of distributors will have it in stock.
This is where most procurement teams leave money on the table. For a single MCCB, price quotes from three different distributors on the same part number can easily vary by 20–40%. For larger orders or urgent sourcing, the range is even wider.
The reasons for this variability:
Post your part number and quantity on BreakerQuote. Get competing quotes from verified distributors and see the real market price — not list price.
⚡ Get Competing QuotesIf you're hiring an electrician to install the replacement breaker, typical labor costs in 2026:
For industrial facilities with in-house electrical teams, labor is an internal cost — but the downtime cost is often the real driver of urgency. Every hour a production line is down because a replacement breaker is on backorder can cost thousands of dollars.
For residential and small commercial breakers, always buy new. The part cost is low enough that a reconditioned or surplus breaker isn't worth the traceability and warranty uncertainty.
For large MCCBs and LVPCBs, reconditioned equipment from a certified reconditioning facility is a legitimate option when:
Never use uncertified surplus or "as-is" breakers on critical circuits. The cost of a failure — in downtime, equipment damage, or injury — far exceeds any savings.
Circuit breaker replacement costs range from under $10 to over $50,000 depending on type and size. For most commercial and industrial buyers, the biggest opportunity isn't in the part itself — it's in getting multiple quotes. Distributor pricing varies significantly, and competitive sourcing is the most reliable way to find the best price and fastest delivery on the same part number.
