Electrical Power and Control - a Talladega, AL-based specialist electrical component supplier and repair company - releases a new guide to the control components of the Masterpact Square D NW Breaker.
—
The latest guide offers readers a detailed exploration of the control circuit options and identification codes of this crucial electrical device. The piece seeks to give engineers a deeper understanding of how the unit works to promote safer and more efficient operation, highlighting the importance of matching control components with the correct voltage for one's system.

The Masterpact NW Breaker contains four control components, each with an associated code. The shunt trip function - which opens the breaker when triggered by an overload, short circuit, or external signal - is represented by the MX code while the reverse shunt close function is handled by the XS component. Electrical Power and Control explains that these components are complemented by the under-voltage coil (MN), which prevents equipment from being damaged due to inadequate voltage, and the charging motor (MCH) which compresses the spring needed to close the breaker - storing enough force to overcome any friction.
The guide notes that the shunt close and shunt trip components are interchangeable parts despite their opposite functions within the breaker mechanism - the placement of these coils determines whether they unlock the trip or close functions. When used as an MX coil, these components open the breaker contacts, using a magnetic field to pull a designated latch which in turn activates a spring mechanism. The same component installed at a different point (XF) releases the stored energy from the charged spring which forces the contacts back together.
“This clever design offers some flexibility during maintenance or troubleshooting,” the guide states. “A qualified electrician can swap the coil’s location to convert it from a trip to a close function (or vice versa) if necessary.”
The piece highlights that simple missteps in voltage matching can have serious consequences for both human safety and the preservation of connected equipment. For example, using low-voltage coils in high-voltage systems will not generate enough magnetic force to be effective and compromise safety and functionality.
These mistakes can be easily avoided - as the guide says, “determining the correct voltage is straightforward. The voltage rating is typically printed directly on the plastic label of the control component you’re replacing. Additionally, the NW circuit breaker’s technical specifications or user manual will list compatible voltage ratings for its control components.”
The Electrical Power and Control website features a video guide that demonstrates all of these secondary control functions as well as other resources for engineers including a step-by-step guide to replacing worn-out MCH motors.
