What Does a Circuit Breaker Cost? (2025 Price Guide by Amp & Brand)

Published: 2025-06-03 | 7 min read | Category: Buying Guide

A circuit breaker costs between $5 and $80,000 depending on the type, amperage, and application. Residential single-pole breakers (15-30A) cost $5-$25. Commercial molded case breakers (100-1200A) cost $200-$6,000. Industrial air circuit breakers (800-4000A) cost $8,000-$80,000. Surplus and reconditioned options reduce these prices by 30-70%.

The US circuit breaker market is valued at approximately $8.2 billion annually (Grand View Research, 2024), with residential breakers accounting for the highest unit volume but industrial breakers accounting for the highest dollar volume. Price per unit spans a 16,000x range from the cheapest residential breaker to the most expensive industrial ACB.

Residential Circuit Breakers: $5-$80

Residential breakers are the most affordable category because they're mass-produced, high-volume parts with multiple competing manufacturers.

| Type | Price Range | Examples | |---|---|---| | 15-30A single-pole | $5-$25 | Square D QO120, Eaton BR120, Siemens Q120 | | 15-50A double-pole | $10-$40 | Square D QO230, Eaton BR230, Siemens Q230 | | 100-200A main breaker | $20-$80 | Square D QO2200, Eaton BR2200B | | AFCI combination breaker | $40-$80 | Square D QO120CAFI, Eaton BRCAF120 | | GFCI breaker | $35-$65 | Square D QO120GFI, Siemens QF120A |

**Key takeaway:** For residential breakers, prices are consistent across brands. The main cost driver is special protection features (AFCI/GFCI), which add $25-$55 to the base price of a standard breaker.

Commercial MCCBs: $200-$6,000

Commercial molded case circuit breakers cost 10-100x more than residential breakers because they handle higher fault currents, use more material, and require precision manufacturing.

| Frame / Amperage | New Price | Surplus Price | Savings | |---|---|---|---| | 100A 3-pole (HFD, EDB, FD) | $200-$600 | $80-$250 | 50-60% | | 200-400A 3-pole (HJD, EHD, JD) | $400-$1,500 | $150-$600 | 55-60% | | 600-800A 3-pole (HKD, EKD, KD) | $800-$3,000 | $300-$1,200 | 55-60% | | 1000-1200A 3-pole (HLD, ELD, LD) | $1,500-$6,000 | $600-$2,500 | 55-60% |

**Key takeaway:** Surplus pricing consistently delivers 50-60% savings on commercial MCCBs. For most applications, surplus is the optimal choice — same part, never installed, at half the price.

Industrial Air Circuit Breakers: $8,000-$80,000

Air circuit breakers are the most expensive category, used in main switchgear for large commercial buildings, data centers, and industrial facilities.

| Amperage | New Price | Reconditioned Price | Savings | |---|---|---|---| | 800-1200A ACB | $8,000-$20,000 | $3,000-$9,000 | 55-65% | | 1600-2000A ACB | $15,000-$40,000 | $6,000-$18,000 | 55-60% | | 3000-4000A ACB | $25,000-$80,000 | $10,000-$35,000 | 55-60% |

**Key takeaway:** At this price level, reconditioned breakers offer massive savings ($10,000-$45,000 per unit) while performing identically to new when properly rebuilt to NETA standards.

What Drives Price Up or Down

Obsolescence is the single biggest price driver for industrial breakers — a discontinued breaker with limited remaining supply can cost 2-5x more than its current-production equivalent. Condition (new vs. surplus vs. reconditioned) is the second biggest factor, offering 30-70% savings on the same part.

Frequently Asked Questions

How much does a 200A circuit breaker cost?

A 200A residential main breaker (Square D QO2200, Siemens Q2200) typically costs $30–$80 new. A 200A commercial MCCB (Square D QDL22200, Eaton EHD) runs $150–$600 depending on the frame and interrupting rating.

How much does a 400A circuit breaker cost?

A 400A 3-pole commercial MCCB (Square D I-Line, Eaton PowerDefense, Siemens HFD) typically costs $400–$1,500 new depending on the frame, interrupting rating, and trip type. Surplus stock is often available at 30–50% below new pricing.

Why are some circuit breakers so expensive?

High-amperage breakers, electronic trip units, draw-out construction, and obsolete/discontinued models all drive prices up. A 2000A air circuit breaker with an LSIG electronic trip unit can cost $15,000–$40,000 new because of the precision engineering and low production volumes involved.
