EATON NHI-E2-11-PKZ0-PI Front-Mount Auxiliary Contact Module, 1NO/1NC, Push-in Terminals

The EATON NHI-E2-11-PKZ0-PI is a high-quality front-mounted auxiliary contact module specifically engineered for integration with PKZ motor-protective circuit breakers. This compact device provides essential status signaling capabilities, allowing for the monitoring of circuit breaker positions within complex electrical distribution and industrial automation systems. Featuring a robust 1NO/1NC contact configuration, it ensures reliable performance in demanding environments.

Advantages

The primary advantage of this auxiliary contact module is the implementation of advanced push-in terminal technology, which significantly reduces installation time and ensures secure, vibration-resistant connections without the need for specialized tools. Its front-mounting design allows for space-efficient integration directly onto the circuit breaker, maintaining a compact footprint in control panels. The module provides clear and accurate feedback on the operational status of the protective device, facilitating seamless integration into control circuits and automated monitoring systems.

Suitable for

• Industrial automation control panels
• Motor protection and control systems
• Electrical distribution switchgear
• Status signaling and remote monitoring applications

When it may not be suitable

This module is specifically designed for use with compatible EATON PKZ series motor-protective circuit breakers and may not be compatible with other brands or different series of circuit breakers. It is not intended for high-power switching applications, as it is strictly an auxiliary signaling device.

Key specifications

• Contact configuration: 1 Normally Open (NO) and 1 Normally Closed (NC)
• Mounting type: Front-mount
• Connection technology: Push-in terminals
• Compatibility: EATON PKZ motor-protective circuit breakers

How to use

To install the module, ensure that the power supply to the circuit breaker is disconnected. Align the auxiliary contact module with the designated front-mounting interface on the PKZ circuit breaker and snap it into place until it is securely seated. Connect the control wires into the push-in terminals by inserting the stripped conductor ends directly into the terminal ports. Verify that the connections are firm and that the module is correctly aligned before restoring power to the system.

What to consider before purchase

• Verify compatibility with your specific PKZ circuit breaker model
• Ensure the control circuit voltage matches the module ratings
• Confirm available space within the control cabinet for front-mounted accessories

Usage recommendations

Always follow local electrical safety regulations and manufacturer guidelines during installation. Ensure that the conductors used are of the appropriate gauge for the push-in terminals to maintain a reliable electrical connection.
