Product Description

Murray offers a wide array of thermal-magnetic circuit breakers that are the key element for overload and short-circuit protection of your home’s electrical system. To provide additional protection Murray offers circuit breakers to protect against severe electrical shock or electrocution, mitigate the risk of electrical fires and protect against damaging surges and voltage spikes. Circuit breakers are intended for switching and protection of your home's wiring from high temperatures caused by excess current higher than the rating of the wire. While thermal-magnetic circuit breakers are the key element for overload and short-circuit protection of your electrical system, there are potentially dangerous conditions that do not involve over current. Murray strongly recommends against the use of "used" breakers. The installation of used breakers in a Murray panel will void the warranty on the panel. Murray does not sell used breakers and has not approved any 3rd party sellers to do so.

From the Manufacturer

Murray plug in circuit breakers are intended for use in Murray load centers or meter combinations. The double pole Murray breakers may be used in 1 or 3-phase load centers and are 240V rated. To ensure the warranty on a Murray panel is not voided, the use of Murray breakers is required.

Works well but was a little nervous digging into the fuse panel myself. Best to hire a professional if you’re needing to replace a fuse/breaker.

Worked for me although looked like it was used. But there is a Siemens Q240 that is the same since Murray circuit breakers are no longer being manufactured.

The picture on the item's page was misleading because it showed a different model number, but this is the correct item and works as expected.

Product came on time and worked perfectly. The price was excellent; my EV now charges in 3 hours. I couldn't be happier.
