ABB OA7G10 Auxiliary Contact 1NO for Switches up to 125A

The ABB OA7G10 is a high-quality auxiliary contact engineered for seamless integration with ABB switches rated up to 125A. This component features a 1NO (normally open) configuration and is specifically designed for left-side mounting, providing reliable signal feedback for various industrial and commercial electrical switching applications. Its compact design ensures it fits efficiently within your electrical control panels while maintaining precise monitoring capabilities.

Advantages

This auxiliary contact offers exceptional reliability and durability, consistent with ABB's high manufacturing standards. Its 1NO configuration allows for straightforward integration into existing control circuits, facilitating effective status monitoring of the main switch. The compact dimensions ensure that it does not occupy excessive space, making it an ideal choice for installations where panel real estate is limited. The grey finish provides a professional appearance that matches standard industrial electrical equipment.

Suitable for

• Industrial electrical control systems
• Commercial power distribution panels
• Status monitoring of switches up to 125A
• Automation and signaling circuits

When it may not be suitable

This auxiliary contact is specifically designed for left-side mounting on compatible ABB switches. It may not be suitable for applications requiring right-side mounting or for use with switchgear brands other than ABB. Additionally, it is not intended for high-current power switching, as it is strictly a signal-level auxiliary component.

Key specifications

• Configuration: 1NO (Normally Open)
• Compatibility: ABB switches up to 125A
• Mounting position: Left side
• Colour: Grey
• Width: 11 mm
• Depth: 21 mm
• Height: 37 mm

How to use

To install the ABB OA7G10, ensure that the main switch is completely disconnected from the power supply to prevent electrical hazards. Align the auxiliary contact with the designated mounting interface on the left side of the compatible ABB switch. Secure the component firmly according to the switch manufacturer's installation guidelines. Once mounted, connect the signal wires to the terminals to integrate the contact into your monitoring or control circuit. Verify the connection by testing the signal feedback before restoring power to the system.

What to consider before purchase

• Verify that your specific ABB switch model supports left-side auxiliary contact mounting.
• Ensure the switch current rating does not exceed 125A.
• Confirm that the 1NO configuration meets your circuit requirements.
• Check available space in your enclosure to accommodate the 11 mm width of the contact.

Usage recommendations

Always perform installation and maintenance by a qualified electrician to ensure safety and compliance with local electrical regulations. Regularly inspect the connection points to ensure they remain secure and free from oxidation.
