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.

A shunt trip is a circuit breaker protector that can remotely trip a breaker. 

Our everyday electrical systems are complex networks of breakers, wiring, receptacles, and more. And each component is essential to bring the electricity where we need it and keep production equipment running, like HVAC systems and lighting.

Each component has its place, including shunt trip circuit breakers, which are optional but can be an important component in the system. This particular piece is an accessory to the main breaker, adding extra protection to the system. This article explains shunt trips, how they work, and why they’re important.
