Secondary Controls On a Square D MasterPact NW Breaker

Understanding Control Components of the Masterpact Square D NW Breaker

The Masterpact Square D NW breaker is a crucial electrical device used in various electrical applications. To delve deeper into its functionality, we’ll explore the control circuit options and associated identification codes. In this article, we’ll break down these codes, share a fun fact about the breaker, and emphasize the importance of matching control components with the correct voltage for your system.

Cracking the Masterpact NW Breaker Code:

To better understand the Masterpact NW breaker, let’s decipher the identification codes for its control components:

1. **MX – Shunt Trip:** The MX code represents the shunt trip function. This component plays a role in opening the breaker when needed.

2. **XF – Shunt Close:** The XF code stands for shunt close. Unlike the shunt trip, this component helps close the breaker.

3. **MN – U.V. Under Voltage Coil:** The MN code corresponds to the under-voltage coil, which monitors and responds to voltage changes.

4. **MCH – Charging Motor:** MCH denotes the charging motor, an essential part of the breaker’s operation.

A Fun Fact:

Here’s an interesting tidbit about the Masterpact NW breaker: the shunt trip and shunt close coils are interchangeable parts. What sets them apart is their installation location within the breaker. Depending on where you place the coil, it engages a different paddle in the mechanism, enabling either a trip/open or close function. It’s like flipping a switch to change its role!

A Word of Caution:

When dealing with control components for the Masterpact NW breaker, it’s crucial to exercise caution. Always ensure that you replace control components with the same voltage as your system requirements. These specifications are typically listed on the plastic coil label of the component you’re replacing.

Understanding the control components and identification codes of the Masterpact Square D NW breaker is vital for its proper operation. By decoding these codes, learning about their interchangeability, and adhering to voltage requirements, you can ensure this essential electrical device’s efficient and safe functioning. Whether you’re a seasoned professional or just starting in the field, this knowledge will help you harness the full potential of the NW breaker in your applications.
