Siemens Circuit Breakers in Chicago, IL: Where to Buy
Published: 2026-07-04 | 6 min read | Category: Buying Guide
Chicago has one of the largest concentrations of Siemens electrical equipment in the United States. The city's iconic high-rises, massive industrial base, and dense commercial districts all rely heavily on Siemens breakers — from QP residential breakers in Wrigleyville two-flats to Sentron MCCBs in Loop skyscrapers. The legacy ITE (Imperial Type E) brand, which Siemens acquired in 1983, means many older Chicago buildings have Siemens-compatible panels requiring exact replacement breakers.
Why Siemens is Common in Chicago
- **ITE legacy:** ITE was headquartered in Philadelphia but had massive market share in the Midwest. Thousands of Chicago buildings have ITE/Siemens panels.
- **High-rise market:** Siemens Sentron and VL breakers are popular in Chicago's high-rise construction
- **Industrial base:** Chicago's manufacturing corridor (south side, suburbs) uses Siemens motor protection
- **City of Chicago code:** Chicago has its own electrical code (more stringent than NEC in some areas), and Siemens equipment is well-established with Chicago inspectors

Chicago-Specific Applications
Loop & River North High-Rises
Chicago's downtown high-rises have demanding electrical requirements: - Siemens BQD bolt-on breakers in floor panelboards - Sentron 3VA MCCBs for riser distribution (LSIG for coordination) - VL power circuit breakers in basement switchgear - Ground-fault protection of equipment (GFPE) on main service - High KAIC ratings (65kA+) due to large utility transformers - Selective coordination for emergency systems (Chicago requires this for all high-rises)
Residential (Wrigleyville, Lincoln Park, Oak Park, Evanston)
Chicago's housing stock includes many older buildings: - QP breakers for existing Siemens/ITE panels - AFCI breakers for bedroom circuits (required on renovation) - GFCI breakers for kitchens, bathrooms, basements - Tandem breakers (QT) for panel space limitations in older panels - 2-flat and 3-flat buildings often have multiple Siemens panels
Industrial (South Side, Cicero, Elk Grove Village)
- Sentron 3VA for motor control centers
- 3RV motor protection breakers
- High-KAIC breakers for large manufacturing transformers
- Motor circuit protectors for CNC and press equipment
- Legacy ITE breakers for maintenance replacements
Healthcare (Northwestern, Rush, UChicago Medicine)
- Sentron 3VA with LSIG for NEC 517 selective coordination
- High-KAIC for large hospital services
- Coordinated breaker systems for essential electrical systems
- Isolated power panel breakers for operating rooms
ITE to Siemens Crossover Guide
Many Chicago buildings still have ITE labels on their panels:
| ITE Product | Siemens Equivalent | Notes | |------------|-------------------|-------| | ITE EQ load center | Siemens EQ | Same panel, same breakers | | ITE BL breaker | Siemens BL | Direct replacement | | ITE QP breaker | Siemens QP | Direct replacement | | ITE Sentron | Siemens Sentron | Same catalog numbers | | ITE HB/HBQ | Siemens HBQ | Legacy, limited availability | | ITE FXD | Siemens FXD | Legacy frame |
City of Chicago Electrical Code Differences
Chicago has its own electrical code (not NEC directly):
| Requirement | Chicago Code | NEC | |------------|-------------|-----| | Conduit | EMT or rigid required everywhere | Romex allowed in residential | | AFCI | Follows NEC 210.12 | Same | | GFCI | Follows NEC 210.8 | Same | | Permits | Required for all electrical work | Varies by jurisdiction | | Inspections | City of Chicago inspectors | AHJ inspectors |
The conduit requirement means Chicago electricians work with breakers in metallic panels more often than in other cities. This affects breaker selection for grounding and bonding.
Common Chicago Replacement Scenarios
Condo Renovation Chicago condo renovations often require: - Matching existing Siemens QP or BQD breakers - Adding AFCI for bedroom circuits - Adding GFCI for kitchen/bathroom - Panel space is often limited in older buildings
High-Rise Maintenance - Replacing failed BQD breakers in floor panels - Upgrading to LSIG for coordination compliance - Emergency system breaker replacement - Exact match required for UL listing compliance
Two-Flat/Three-Flat Upgrade - Upgrading from 100A to 200A service - Adding circuits for modern loads (AC, EV, kitchen) - Often requires new panel with more spaces

What Siemens breakers do Chicago high-rises use?
Chicago high-rises typically use Siemens BQD bolt-on breakers in panelboards, Sentron 3VA MCCBs for distribution, and VL power circuit breakers in main switchgear. The high-rise application requires high KAIC ratings (42-65kA minimum), LSIG electronic trip for selective coordination, and ground-fault protection of equipment (GFPE) on services over 1,000A. Many older Chicago high-rises have ITE panels (now Siemens) requiring exact replacement breakers.
Are ITE breakers the same as Siemens?
Yes. Siemens acquired ITE (Imperial Type E) in 1983. All ITE circuit breakers are now manufactured under the Siemens brand with the same catalog numbers and specifications. If your Chicago building has an ITE panel, the Siemens equivalent is a direct replacement. Common ITE/Siemens crossovers include the EQ load center (now Siemens EQ), BL breakers, and Sentron series MCCBs.
