Pushmatic 100 Amp Circuit Breaker

Electrical Supplies Unlimited (ESU) buys and sells Pushmatic 100 amp circuit breakers for residential, commercial and industrial electrical applications. Also known as ITE Bulldog breakers, Pushmatic circuit breakers were used in electrical distribution panels and equipment manufactured during an earlier generation of electrical systems. Finding the correct replacement or sourcing an obsolete breaker can be challenging, particularly when the original equipment has been discontinued.

With more than 40 years of experience in the electrical supply industry, ESU specializes in locating new, used, surplus, obsolete and hard-to-find circuit breakers. Whether you need a Pushmatic 100 amp breaker for an existing electrical panel or have surplus Pushmatic equipment to sell, our team can help identify the appropriate product based on its manufacturer markings, model number and electrical specifications.

Pushmatic 100 Amp Breaker Types and Models

Pushmatic 100 amp circuit breakers are available in different configurations. Two important examples are the two-pole UBIP2100 replacement breaker and the three-pole ITE P43100 molded-case circuit breaker. Although both carry a 100 amp rating, they serve different electrical applications and are not interchangeable.

Pushmatic UBIP2100 – 100 Amp 2-Pole Circuit Breaker

The UBIP2100 is a two-pole, 100 amp replacement circuit breaker designed for compatible Pushmatic and Bulldog load centers. Common published specifications for this replacement model include:

• 100 amp current rating
• Two-pole configuration
• 120/240 volt AC rating
• 10,000 amp interrupting capacity (AIC)
• Bolt-on mounting design

The UBIP2100 is a currently manufactured replacement model offered by Connecticut Electric. Its compatibility with a particular Pushmatic panel should still be confirmed before purchase or installation. The model number, panel identification and equipment requirements should be checked rather than relying on amperage alone.

ITE P43100 – 100 Amp 3-Pole Pushmatic Circuit Breaker

The ITE P43100 is a three-pole, 100 amp molded-case circuit breaker associated with the Pushmatic product family. Published product specifications identify this model as a three-phase breaker rated for 240 volts, with a 10 kA interrupting capacity at 240 volts and bolt-on mounting.

This configuration is different from the two-pole UBIP2100 replacement breaker. When sourcing a P43100 or another three-pole Pushmatic breaker, it is important to verify the exact catalog number, voltage rating, interrupting capacity and application of the original equipment.

We buy individual breakers as well as larger quantities of surplus electrical components.

How to Identify the Correct Pushmatic 100 Amp Breaker

Before ordering a Pushmatic 100 amp circuit breaker, identify the existing breaker and electrical panel as accurately as possible. Several details can affect compatibility, and two breakers with the same amperage rating may have different mounting arrangements, pole configurations or electrical characteristics.

• Model or catalog number: Look for the identifying number printed or stamped on the breaker.
• Number of poles: Confirm whether the application requires a two-pole or three-pole breaker.
• Voltage rating: Match the breaker rating to the electrical system and equipment requirements.
• Interrupting capacity: Verify that the breaker has an appropriate AIC rating for the installation.
• Panel compatibility: Confirm the exact panelboard or load center model and approved breaker type.

Providing a photograph of the existing breaker label and panel identification can help narrow down the correct replacement. A qualified electrician should verify the application and compatibility before installation.

Pushmatic and Bulldog Circuit Breakers

Pushmatic and Bulldog are names associated with older ITE electrical distribution equipment. These breakers are recognizable for their distinctive push-button operating mechanism rather than the conventional toggle handle found on many modern circuit breakers. Because many original Pushmatic panels have been in service for decades, locating the correct replacement parts can require additional model and application research.

When working with older electrical equipment, the condition of the panel and breaker should also be evaluated. Age, corrosion, heat damage, worn connections and mechanical operating problems can affect equipment performance. Replacing an individual breaker does not necessarily address problems elsewhere in an aging electrical panel. Have the equipment inspected by a qualified electrician when condition or safe operation is uncertain.

Federal Pacific 100 Amp Circuit Breaker

A Federal Pacific 100 amp circuit breaker is used in electrical distribution equipment to provide overcurrent protection for circuits in commercial, industrial and certain residential applications. Federal Pacific Electric (FPE) manufactured several breaker families over the years, including molded-case circuit breakers and Stab-Lok models. A 100 amp breaker can have different pole configurations, voltage ratings, frame types and interrupting capacities depending on its model. Whether you are maintaining older electrical equipment or searching for a replacement, identifying the exact breaker type and catalog number is essential.

Federal Pacific 100 Amp Breaker Models

Federal Pacific 100 amp circuit breakers were manufactured in different configurations for specific panelboards and electrical distribution systems. Models may include two-pole and three-pole breakers, as well as different frame and mounting styles. Federal Pacific manufactured several families of molded-case circuit breakers for commercial and industrial electrical distribution systems. Available configurations vary by model, including different amperage ratings, pole configurations, voltage ratings and interrupting capacities. Identifying the exact catalog number and equipment application is essential when sourcing a replacement or locating obsolete Federal Pacific electrical equipment, while other FPE molded-case breaker families serve larger commercial and industrial applications. These models are not interchangeable simply because they share the same amperage rating. Always verify the catalog number, voltage, pole count, interrupting rating and equipment compatibility before selecting a replacement.

When searching for a 100 amp FPE circuit breaker, having the information from the breaker identification label can make locating the correct equipment much easier. Useful details include the complete model or part number, manufacturer markings, amp rating, voltage rating and number of poles. Older Federal Pacific breakers can be difficult to identify or replace, particularly when the original equipment has been discontinued. ESU specializes in sourcing obsolete and hard-to-find electrical components and can help locate specific Federal Pacific breakers depending on availability.
