What brand of breaker is used for Murray load centers?
However, for an optimal use of the original Murray Load Centers, the best breaker brand substitute is Siemens. Not only is Siemens known for their quality products, but they are also the UL-listed brand for Murray.
Why does my Murray breaker fail?
Failures among Murray breakers aren’t uncommon. They are usually caused by too much flow of current , leaving the bimetal exposed to extreme heat. Over time, the metal strips weaken under the effects of electrical currents, making the breaker less likely to trip.
What is Murray panel?
The Murray panel is a classic — that’s why many own a breaker box of its kind. Since the release of circuit breakers in the market, electrical panels replaced the outdated fuse boxes, and this brand is very innovative, being one of the best panel upgrades available.

What Breakers Are a Plausible Replacement for Murray Circuit Breakers?
There are several types of circuit breakers on the market that can replace a Murray .
What Are the Features of a Murray Circuit Breaker?
These breakers consist of two alternate switching mechanisms: a bimetal switch and an electromagnet.
Why are circuit breakers important?
They act as automatic electrical switches to protect an electrical circuit from damage, due to excess current caused by an overload or short-circuit. Circuit Breakers exhibit this function by inhibiting current flow once a fault is present.
How long does it take for a Murray breaker to extinguish?
Murray breakers have the advantage of exhibiting rapid excess current control, extinguishing the arc between breaker contacts in as little as 4 msec.
How does a circuit breaker work?
The idea is simple: A circuit breaker is a device that automatically disconnects an electric circuit when the current levels become too high. By interrupting the circuit, the breaker prevents overloads and the resultant risk of fire or explosion.
Why are Murray circuit breakers weak?
Susceptible to Wear and Tear: The metal strips within the Murray circuit breakers become weaker as the strips are exposed to an electrical current. This affects the breakers ability to trip and exposes the circuit to overload.
What was the first circuit breaker?
Murray circuit breakers were among the first circuit breakers to appear on the market. The first type of breakers available were thermal-magnetic circuit breakers, utilizing thermal and magnetic features to control excess current during a fault.
What does specified breakers mean?
Specified breakers mean the manufacturer has tested the breakers in the panel and listed them to be used in that panel. You have probably noticed “UL Classified” and interchangeable circuit breakers around the market.
Is Square D a code violation?
Square D insists that this is a code violation which will result in their warranty void. They went as far as to say that you may lose your license. However, Eaton and the Underwriters Laboratory (UL) would disagree.
Can you use UL classified breakers in panelboard?
Otherwise, just replace the same type of existing breakers in the box. Manufacturers would want to specify their own breakers for use in their panelboards for obvious financial reasons. However, remember you have options with UL Classified breakers like the chart above. Some electricians use Classified breakers for obvious reasons, whether for price, availability, or convenience. But which ever circuit breakers you go with, make sure to install them safely.
Is using breakers not listed or labeled a violation of the electrical code?
They site the National Electrical Code (NEC) Section 110-3 (b), which states that using breakers not listed or labeled is a code violation. Their argument is for public safety drawing evidence from past accidents due to the use of Classified breakers in their panel.
Can UL Classified breakers be used for panels?
These breakers meet UL and NEC code regulations. UL has stated that people must adhere to all manufacturer supplied instructions. Moreover, UL also stated that Classified breakers can be used for their approved panels. ( Source: UL Marking and Application Guide Panelboards ). On the note of warranty void, manufacturers cannot void their warranty if the replacement part has proven to be safe by a third-party, for instance UL (Magnusson-Moss Warranty Act).
