Eaton AZ-XHI11 Auxiliary Contact for Circuit Breakers

The Eaton AZ-XHI11 auxiliary contact is a precision-engineered component designed specifically for integration with Eaton AZ series circuit breakers. This device serves as a critical interface for monitoring the switching status of electrical protection equipment, providing reliable feedback through its 1NO (normally open) and 1NC (normally closed) contact configuration. Its compact design and universal fitting capability allow for seamless installation in diverse electrical distribution boards, ensuring that system status can be tracked accurately in both industrial and commercial environments.

Advantages

The primary benefit of the Eaton AZ-XHI11 is its ability to provide real-time status signaling, which is essential for maintaining safety and operational oversight in complex electrical systems. Its robust construction ensures consistent performance under standard operating conditions, while the universal mounting design simplifies the installation process for technicians. By offering both normally open and normally closed contacts, it provides versatile signaling options that can be adapted to various control and monitoring requirements without the need for additional complex hardware.

Suitable for

• Monitoring the status of circuit breakers in distribution panels
• Integration into automated control and signaling systems
• Industrial electrical infrastructure management
• Commercial building power distribution monitoring

When it may not be suitable

This auxiliary contact is specifically designed for use with the Eaton AZ series of circuit breakers and may not be compatible with other series or brands. It is not intended for high-power switching applications and should only be used for signal-level monitoring within the specified temperature and environmental parameters.

Key specifications

• Contact configuration: 1NO + 1NC
• Width: 9 mm
• Depth: 65.5 mm
• Height: 90 mm
• Operating temperature range: -5 to 40 °C
• Color: White
• Fitting type: Universal

How to use

Installation should be performed by a qualified electrician in accordance with local safety regulations. Before beginning, ensure that the main power supply to the circuit breaker is disconnected. The auxiliary contact is designed to be attached to the side of the compatible AZ series circuit breaker. Align the device with the mounting interface on the breaker and secure it firmly. Once attached, connect the signaling wires to the appropriate terminals according to your control circuit diagram. After installation, verify the mechanical and electrical operation by toggling the circuit breaker and observing the status change in your monitoring system.

What to consider before purchase

• Verify compatibility with your specific Eaton AZ series circuit breaker model
• Ensure the operating environment remains within the -5 to 40 °C temperature range
• Confirm that the signaling requirements match the 1NO + 1NC contact configuration
• Check available space in the distribution board for the 9 mm wide module

Usage recommendations: Always ensure that the auxiliary contact is securely fastened to the circuit breaker before energizing the system. Regularly inspect the connections to prevent signal loss due to vibration or thermal expansion.
