CH vs BR Breakers and Panels: What’s the Difference and Where Are They Used?

When choosing an electrical panel or circuit breaker, Eaton (formerly known as Cutler-Hammer) stands out as one of the most trusted manufacturers in residential, commercial, and light-industrial electrical systems. Among Eaton’s most commonly used product lines are the BR and CH breaker and load center series.

CH and BR breakers are low-voltage circuit breakers designed to protect electrical circuits from overloads and short circuits. Each breaker type is specifically engineered to fit only its corresponding panel, ensuring proper mechanical compatibility, dependable electrical connections, and full compliance with UL and NEC requirements.

Likewise, CH and BR panels are two widely used Eaton load centers. While both perform the same essential function i.e. safely distributing electrical power, their build quality, interrupting ratings, and intended applications differ significantly. Although both systems are UL-listed and NEC-compliant, CH and BR breakers and panels are not interchangeable.

In the following guide, we will explain the difference between CH vs BR breakers, CH vs BR load centers, and identifies where each system is best suited for use.

What is a BR Breaker?

A BR breaker is Eaton’s standard residential circuit breaker line, widely used in homes across North America. BR breakers are cost-effective, reliable, and designed for general residential electrical loads.

BR breakers are 1-inch per pole, 120/240V rated, and fit only BR-type load centers. They are easily identified by their black handle, similar in appearance to many other residential breaker brands.

BR breakers are available in single-pole, double-pole, tandem (two circuits in one slot), and quad configurations. Eaton also offers GFCI, AFCI, and dual-function BR breakers, including Plug-On Neutral (PON) versions for faster installation and reduced panel wiring congestion.

Two-pole BR breakers use an external handle tie or internal common trip, depending on the model, to disconnect both ungrounded conductors during a fault.

BR breakers are primarily intended for residential homes, apartments, and light commercial applications where fault-current levels are moderate.

Good to Know:

BR stands for Bryant, a company that originally manufactured these load centers and circuit breakers before the brand became part of Eaton. Today, BR load centers and breakers are produced under the Eaton name.

Key Features of BR Breakers

Designed exclusively for BR panels
Rated for 120/240V single-phase systems
Available in 10 to 100A (current rating)
Typical interrupting rating of 10 kA
Black handle design
Available in Duplex and Quadplex (CTL & Non CTL) for standard, tandem, GFCI/AFCI, and dual-function versions
Budget-friendly and widely available

What is a CH Breaker?

A CH breaker is Eaton’s premium residential and commercial-grade circuit breaker, originally developed under the Cutler-Hammer brand. These breakers are known for their robust construction, copper bus compatibility, and high fault-current ratings.

CH breakers are ¾-inch per pole, 120/240V rated, and are designed exclusively for CH load centers. A defining feature of CH breakers is their tan-colored handle, which makes them easy to identify in the field.

CH breakers are available in single-pole, double-pole, and triple-pole configurations, along with advanced protection options such as GFCI, AFCI, and dual-function (AFCI + GFCI) breakers. Two-pole and three-pole CH breakers use a common internal trip mechanism, ensuring all phases disconnect simultaneously when a fault occurs on any one phase.

Because of their durability and higher interrupting ratings, CH breakers are commonly used in commercial buildings, premium residential installations, and high fault-current environments.

Good to Know:

CH stands for Cutler-Hammer, another well-known electrical brand that was acquired by Eaton. The CH line continues to be recognized for its higher construction quality and premium performance.

CHF vs. CH: CHF breakers are a subset of the CH line that include a “trip flag” to easily identify a tripped circuit, which standard CH breakers lack.

CHF breakers are designed to be fully interchangeable with older standard CH breakers in Eaton/Cutler-Hammer panels.

Key Features of CH Breakers

Designed exclusively for CH panels
Rated for 120/240V (single-phase and selected three-phase systems)
Current rating is 10-100A
Typical interrupting rating of 10–22 kA
Tan handle for easy identification
Thermal-magnetic trip mechanism
Available in Twin (CHT) for standard, GFCI, AFCI, and dual-function types (in Universal CTL/non-CTL versions)

Key Differences between CH vs BR Breakers

Good to Know:

BR breakers focus on affordability and compatibility with common residential installations.
CH breakers are optimized for long service life, higher reliability, and commercial installations.
CH breakers are often considered commercial-grade, even in residential use.
A CH breaker will not fit in a BR panel, and a BR breaker will not fit in a CH panel.
The latest CHF breakers can be replaced with older CH models and vice versa.
Using the wrong breaker type violates UL listing and NEC 110.3(B).

What is a BR Load Center?

A BR panel is Eaton’s standard residential load center, designed for affordability and ease of installation. BR panels typically use aluminum bus bars and accept 1-inch BR breakers.

These panels are designed for single-phase 120/240V systems, with common main breaker ratings from 100A to 200A (even available in 600A) with max 60 spaces & 42 to 120 circuits. Many modern BR panels support Plug-On Neutral (PON) breakers, reducing wiring time and improving panel organization.

BR panels are widely used in homes, apartments, and small commercial spaces where fault-current levels are relatively low.

Characteristics of BR Panels

Aluminum bus bars
Standard residential short-circuit ratings
Supports tandem and quad breakers
Cost-effective design
NEC and UL compliant

Warning:

CH breakers do not fit BR panels, and BR breakers do not fit CH panels. Only CH and CHD models are interchangable. Forcing mismatched breakers is unsafe and violates manufacturer instructions and NEC requirements.

What is a CH Load Center?

A CH panel is Eaton’s premium load center, designed for higher performance and long-term reliability. CH panels use copper bus bars, which provide superior conductivity, reduced heat buildup, and greater resistance to corrosion compared to aluminum.

CH load centers support ¾-inch CH breakers, allowing more circuits in the same enclosure size. They are also available in Plug-On Neutral (PON) load centers for quicker, easier and cleaner installations. These panels are suitable for single-phase and selected three-phase systems, with main breaker ratings typically ranging from 100A to 400A, depending on configuration such as 120/240V single-phase or three-phase four-wire, 208Y/120V or 240V AC

CH panels are commonly installed in commercial buildings, workshops, industrial facilities, and high-end residential projects in both single-phase and three-phase power supply systems.

Characteristics of CH Panels

Copper bus bars
High short-circuit withstand ratings
Compact breaker footprint
Professional-grade construction
Meets NEC and UL standards

FAQ

Can I use a CH breaker in a BR panel?

No. They are mechanically and electrically incompatible.

Is CH better than BR?

Yes, in terms of durability, fault-current rating, and build quality. BR is better for budget-focused residential projects.

Are CH panels worth the extra cost?

For commercial, industrial, or premium residential installations, yes!. They are premium panels by Eaton.

Can You Use Eaton BR or CH breakers in Square D Homeline or QO Panels?

Caution:

Although an Eaton BR breaker (1-inch) or CH breaker (3/4-inch) may appear to physically fit into a Square D Homeline or QO panel due to similar breaker widths, their use is neither approved nor recommended. Similer is the case for ABB, Leviton, Siemens Breakers i.e. they should not be used in different panels manufactured by different brands. Square D Homeline and QO panels are specifically tested and UL-listed only for use with their corresponding Homeline and QO breakers.

Installing an Eaton BR or CH breaker in these panels can violate NEC and UL listing requirements, void manufacturer warranties, and create potential safety hazards, including overheating or arcing caused by improper bus bar connections.
