What breakers are compatible with Murray?

Murray breakers are compatible with a wide variety of other breakers, including trip-breakers and overload protectors. Square D, Elton, Air, and Cutler-Hammer Circuit Breakers are compatible with Murray Circuit Breakers. Ensure your breaker can handle the machine’s power.

Additionally, it is important to ensure that the mounting bracket of the breaker is compatible with the machine you are using. Some breakers come with their mounts, while others require you to purchase a bracket separately. 

Murray is an excellent choice if you’re looking for a reliable and affordable breaker that you can count on. The following is a list of some of the breakers that are compatible with Murray’s products.

The device is also compatible with trip breakers and overload protectors, as well as direct current machines.

Murry mp3 Breakers:

Murray MP3 breakers are compatible with a wide range of machines, including Murray MPT breakers. They can also be used with trip-breakers and overload protectors. However, they aren’t compatible with direct current. 

If your machine has a Murray mp3 breaker, you will need an inverter.

Murray Pcg Breaker:

Murray PCG breakers are heavy-duty circuit breakers designed for industrial applications such as manufacturing and printing. Besides Murray MPT breaker and Murray MPL, it’s compatible with many other types of machines

Murray mp t trip-breakers:

Murray MPT trip-breakers are among the most popular types of breakers. They work with a wide range of machines, including Murray mp t breakers and Air breakers. However, they are not compatible with the direct current like regular Murray MP T breakers.

Murray mp t overload protectors:

For machines that require extra protection against power surges, Murray MP T overload protectors are a great option. These breakers are compatible with Murray and other standard breakers, and they come with their mounting bracket.

What kind of breakers is compatible with Murray panels?

For Murray panels to be adequately protected, you’ll need breakers that are compatible with them. As a result, when the circuit breaker detects a voltage drop due to the electrical load from your panels, it will trip, and you will not be able to add or remove any more electricity. 

The following is a list of breakers that are compatible with Murray panels.

Square D:

A popular choice for industrial applications is Square D breakers, and they are also able to be used with Murray panels as well. There are several different types of breakers available, so you can be sure to find the right one for your machine by looking at the ratings.


The GE breakers are another popular option for industrial applications. They are compatible with a wide range of machines, including Murray panels. These breakers come in a variety of ratings to meet your needs, just like Square D breakers.


It is also a popular choice for industrial applications to use Cutler-Hammer breakers. You can choose from a range of ratings to suit your needs, and they are compatible with Murray panels.


Machines needing extra protection against power surges can benefit from the use of air breakers. Their compatibility with Murray panels makes them a great choice, and they come in a variety of ratings.

7 Factors that determine the compatibility of breakers with Murray

The compatibility of breakers with Murray panels depends on a few factors. Among these is the type of breaker, the voltage rating of your equipment, and the wiring configuration.

Type of Breaker:

The type of breaker you choose will affect its compatibility with your Murray panel. A square D breaker, for instance, is designed specifically for industrial applications and is not compatible with other equipment. 

It is essential to choose a breaker that is designed to work with Murray panels before you make a purchase.

Voltage Rating:

Depending on the type of breaker you use, your equipment will also require a specific voltage rating. Be sure to select the correct voltage rating for your equipment before you make your purchase.

Power Rating:

A breaker’s power rating refers to the amount of power it is capable of handling before it overheats and needs to be replaced. Your equipment might fail due to overheating, so you must select a high-power rating for your installation to prevent this.

Wiring Configuration:

The wiring configuration will also affect compatibility. Neutral wires are required for some breakers to function properly. Ensure that all wires are properly grounded before connecting them to a breaker.

Frequency Range:

There are some breakers with frequency ranges that are incompatible with other equipment. Consult your manual or wiring diagram to verify compatibility and select the correct breaker.

Amperage Rating:

A breaker’s amperage rating indicates how much current it can handle. The rating is important because too much or too little current will damage your equipment, while too little current will not overload the breaker.

Mounting Positions:

Some breakers need to be mounted in a specific position. Depending on the breakers, screws may be required for mounting them. Before buying a breaker, ensure that the mounting location is compatible.

What are the limitations of Murray Circuit Breakers?

There are several limitations to Murray Circuit Breakers that should be considered before purchasing. They are interchangeable with a few other types of breakers. 

Secondly, they may not be compatible with other equipment in your installation due to their limited frequency range.

A third reason for choosing a high-power breaker is that the amperage rating is low compared to the breaker ratings of more popular brands. Murray Circuit Breakers are designed to be mounted in specific positions and cannot usually be attached with screws like other breakers.

Last but not least, some users have reported premature failures of these breakers

What breakers are interchangeable with Murray?

Murray Circuit Breakers are interchangeable with a few breakers. There are two types of circuit breakers: screw-in circuit breakers and surface-mount circuit breakers. 

There are a variety of interchangeable breakers, including Cutler-Hammer and Eaton, Air Circuit Breakers, Siemens, and so on.

Murray Circuit Breakers are limited to a frequency range of 12,000 volts per break, depending on the break. The result of this is that they will not work with other types of equipment in your installation that can operate at higher voltages. 

As a result, they are often used in applications that do not require a high amperage rating but instead are limited by their low-frequency range, as they have a lower output voltage.

Final Thoughts

Therefore, Murray Circuit Breakers are compatible with Cutler-Hammer and Eaton, Air Circuit Breaker, and Siemens. The breakers cannot be fixed with screws. A breaker must be compatible with the following parameters: Power, Voltage, Frequency, Amperage Rating, and Mounting Positions.
