Eaton NZM1/2-XV6 Shaft Extension for Circuit Breakers

The Eaton NZM1/2-XV6 shaft extension is a precision-engineered accessory designed to facilitate the installation of operating handles for Eaton NZM1 and NZM2 series circuit breakers. This component provides the necessary mechanical link between the circuit breaker mounted inside an electrical cabinet and the external operating handle, allowing for flexible positioning and ergonomic control. It is a vital tool for panel builders and electrical engineers who need to adapt switchgear configurations to specific cabinet depths and layouts.

Advantages

This shaft extension offers exceptional flexibility for electrical installations, allowing the operating handle to be mounted at a distance from the circuit breaker itself. Its robust construction ensures a reliable mechanical connection, which is essential for the safe and consistent operation of switchgear systems. The modular design simplifies the assembly process, making it an efficient solution for complex panel building projects where space and component placement are critical factors.

Suitable for

• Extending the operating handle reach for NZM1 and NZM2 circuit breakers
• Panel building and electrical cabinet assembly
• Customizing switchgear layouts for specific cabinet depths
• Industrial and commercial electrical distribution systems

When it may not be suitable

This shaft extension is specifically designed for the Eaton NZM1 and NZM2 series. It is not compatible with other circuit breaker series or brands. Additionally, it should not be used in applications where the required mounting depth exceeds the maximum limit of 600 mm.

Key specifications

• Maximum mounting depth: 600 mm
• Compatibility: NZM1, PN1, N1, NZM2, PN2, N2 series
• Function: Mechanical shaft extension for operating handles

How to use

To install the shaft extension, first ensure that the circuit breaker is properly mounted within the electrical cabinet. Attach the extension shaft to the operating mechanism of the circuit breaker according to the manufacturer's installation instructions. Adjust the length of the shaft to match the required distance between the breaker and the cabinet door. Secure the operating handle to the end of the shaft on the exterior of the cabinet, ensuring that the connection is firm and that the handle operates the breaker smoothly without binding.

What to consider before purchase

• Verify that your circuit breaker model is within the NZM1 or NZM2 series
• Measure the required mounting depth to ensure it does not exceed 600 mm
• Ensure compatibility with your specific cabinet door handle mechanism

Usage recommendations

Always verify that the mechanical connection is secure and that the circuit breaker toggles correctly before energizing the system. Ensure the shaft is cut to the appropriate length to prevent excessive stress on the operating mechanism.
