## Long description

The Eaton 266836 busbar terminal is a high-quality connection component specifically engineered for integration with NZM4 series circuit breakers. This straight-type tunnel terminal ensures a secure and reliable electrical connection, serving as a critical element in industrial power distribution systems and switchgear configurations. Designed for durability and performance, it facilitates efficient power management in demanding electrical environments.
Advantages
This terminal offers exceptional reliability through its robust construction and copper-plated contacts, which provide superior electrical conductivity. The modular design allows for flexible and straightforward installation, making it an ideal choice for complex switchgear setups. By including a dedicated control circuit terminal, it supports precise monitoring and control functions, while the included protective cover ensures safety and compliance with standard operational requirements.
Suitable for
Industrial power distribution panels
Switchgear configurations for NZM4 series circuit breakers
Electrical systems requiring secure and reliable busbar connections
Applications involving 3-pole or 4-pole circuit breakers
This terminal may not be suitable for circuit breakers outside of the specified NZM4 and N(S)4 series. It is also not intended for use without the mandatory protective cover or when using conductor sizes that fall outside the specified range for the control circuit terminal.
Key specifications
Compatibility: NZM4, N(S)4 series circuit breakers
Terminal type: Straight tunnel terminal
Control circuit terminal capacity: 1x0.75-2.5 mm² (18-14 AWG) or 2x0.75-1.5 mm² (18-16 AWG)
Material: Copper-plated contacts
Configuration: Suitable for top or bottom mounting on 3 or 4 pole switches
Installation involves attaching the terminal to the circuit breaker using the provided screw connection points. Ensure that the conductors are properly prepared before insertion. When working with flexible or highly flexible conductors, it is mandatory to use appropriate ferrules to maintain connection integrity. The included protective cover must be installed over the terminal to ensure safe operation.
What to consider before purchase
Verify the compatibility of your specific circuit breaker model (NZM4 or N(S)4).
Ensure the conductor sizes for the control circuit meet your system requirements.
Confirm whether you need terminals for both the top and bottom of the switch, as this kit covers one side.
Always ensure that the power supply is disconnected before performing any installation or maintenance on electrical components. Use ferrules for all flexible conductors to prevent strand damage and ensure a long-lasting, low-resistance connection.
