Eaton NHI-E2-10-PKZ0-PI Auxiliary Contact Module, 1NO, Front Mount, Push-in Terminal

The Eaton NHI-E2-10-PKZ0-PI is a high-quality auxiliary contact module engineered specifically for integration with PKZ motor protection circuit breakers. This front-mounted device provides a reliable 1 normally open (NO) contact, enabling seamless status signaling and control circuit monitoring within industrial automation and electrical distribution panels. Designed for efficiency, it incorporates advanced push-in terminal technology, which significantly reduces wiring time and ensures a secure, vibration-resistant connection without the need for specialized tools.

Advantages

The primary benefit of this auxiliary contact module is its streamlined installation process facilitated by push-in terminals, which allow for rapid conductor insertion and reliable contact integrity. Its compact, front-mount design ensures that it does not increase the footprint of the motor protection circuit breaker, making it ideal for space-constrained control cabinets. Furthermore, the robust construction ensures long-term operational reliability in demanding industrial environments, providing consistent feedback on the switching status of the main circuit breaker.

Suitable for

• Status signaling of motor protection circuit breakers
• Integration into industrial automation control systems
• Electrical distribution and panel building applications
• Remote monitoring of circuit breaker switching states

When it may not be suitable

This module is specifically designed for use with Eaton PKZ series motor protection circuit breakers and is not compatible with other circuit breaker brands or series. It is also not intended for high-power switching applications, as it is strictly an auxiliary signaling device.

Key specifications

• Contact configuration: 1 normally open (NO)
• Mounting type: Front mount
• Connection type: Push-in terminals
• Compatibility: Eaton PKZ motor protection circuit breakers

How to use

To install the module, ensure that the motor protection circuit breaker is de-energized and disconnected from the power supply. Align the auxiliary contact module with the designated front-mounting interface on the circuit breaker. Press the module firmly until it clicks into place. Once mounted, insert the control circuit wires directly into the push-in terminals until they are securely locked. Verify the connection by gently pulling on the wires. After installation, perform a functional test to ensure the auxiliary contact correctly reflects the status of the main breaker.

What to consider before purchase

• Verify compatibility with your specific PKZ circuit breaker model
• Ensure the control circuit voltage and current requirements match the module specifications
• Confirm that the push-in terminal wire gauge range is suitable for your cabling

Usage recommendations

Always follow local electrical safety regulations and manufacturer guidelines when installing auxiliary components. Ensure that the control circuit is properly fused and that all connections are inspected for integrity before energizing the system.
