Circuit Breakers

Circuit breakers are replacement and configuration components for compatible electrical load centers and distribution equipment. Electrical professionals and facility maintenance teams use them when maintaining panel breaker positions, restoring circuit protection, or configuring compatible single-pole, two-pole, bolt-on, and duplex circuit locations.

Use Cases

Maintain compatible load centers

These breakers support replacement and configuration work in compatible electrical panels and distribution equipment. Available options cover single-pole, two-pole, bolt-on, and twin duplex breaker positions.

How to Choose

Match the panel requirements

Confirm the load center accepts the stated breaker type, then match the amperage rating, pole configuration, and mounting format. Select a bolt-on unit only where the panel requires bolt-on installation.

Applications

Support panel replacement work

Representative applications include replacing a specified breaker position, restoring circuit protection in compatible panels, and filling designated panel spaces with the required breaker arrangement.

Planning Guide

Plan the right fit before choosing

Start With Compatibility

Identify the breaker type your load center accepts

The available replacement options are designed for load centers that accept specified breaker types, including RC, QC, QP, QT, Type A, and Type UBIP configurations. Compatibility is the first comparison point because the replacement must match the designated load-center position.

  • Match the breaker type specified for the load center.
  • For bolt-on positions, select a bolt-on breaker format.
  • Check whether the panel position calls for a standard, twin, duplex, or right-clip arrangement.
Match Electrical Configuration

Compare amperage and pole count

The represented selection includes 15A/20A twin duplex, 20A single-pole, 30A single-pole, 30A two-pole, 40A two-pole, 60A two-pole, 70A two-pole, 100A two-pole, and 125A two-pole options. Select the stated amperage and number of poles required for the compatible breaker position.

  • Single-pole options represented include 20A and 30A configurations.
  • Two-pole options represented range from 30A to 125A.
  • A twin 1-pole duplex model provides 15A and 20A circuit protection in one breaker position.
Check Ratings and Physical Details

Review interrupting capacity, listing, and panel-space needs

Many of the represented breakers have a 10,000 AIC rating. Listed options include ETL-listed and UL-listed products. Where applicable, account for physical and installation details such as compact dimensions, 1-inch width, 1/2-inch thickness, a right-hand clip, or a Class CTL rejection clip.

  • Use the stated 10,000 AIC rating when matching application requirements.
  • Review listed status where purchasing or installation documentation calls for it.
  • Confirm special fit details for designated panel-space configurations.
FAQ

Common questions before buying

How do I choose a replacement circuit breaker?

Match the load center's accepted breaker type, the required amperage, pole count, and mounting format. Also review the stated interrupting rating and any fit requirements.

What pole configurations are represented?

The selection includes single-pole and two-pole breakers, plus a twin 1-pole duplex breaker that combines 15A and 20A circuit protection in one position.

When is a bolt-on circuit breaker needed?

A bolt-on breaker is used for a compatible load center designed for bolt-on breaker installation. Confirm that the panel requires this mounting format.

What does 10,000 AIC mean in these product summaries?

It is the stated interrupting-current rating provided for many of the represented circuit breakers and should be matched to application requirements.
