    How to Replace a Murray Breaker

    Murray breakers were phased out in 2019 by Siemens—one of the largest industrial manufacturing companies in Europe. And while these breakers are no longer available in stores, they do have a handful of other compatible replacements on the market.

    Thankfully, Siemens offers many other breakers that are drop-in replacements for Murray. When the company phased out Murray, they provided a cross-reference list for the various replacement models. Siemens also provides a helpline with experienced technicians who can answer any questions about compatible breakers.
