The Eaton 271457 is a high-quality straight tubular connector engineered for secure and reliable electrical terminations. Constructed from durable metallic materials, this component ensures excellent conductivity and robust performance in demanding electrical environments. It is specifically designed as an essential accessory for the NZM2 circuit breaker series, facilitating stable power distribution in both industrial and commercial settings. The modular design allows for flexible installation, supporting both 3-pole and 4-pole switch configurations.
Advantages
This tubular connector offers exceptional mechanical strength and electrical integrity due to its high-grade metallic build. Its design simplifies the installation process for circuit breakers, allowing for efficient integration into complex power systems. The inclusion of a control circuit terminal provides added versatility for monitoring and management tasks. Furthermore, the modular nature of the component ensures compatibility across a wide range of Eaton switchgear, making it a reliable choice for standardized electrical infrastructure.
Suitable for
- Industrial power distribution systems
- Commercial electrical installations
- 3-pole and 4-pole circuit breaker configurations
- Applications requiring secure copper conductor termination
When it may not be suitable
This connector is specifically engineered for the NZM2, PN2, and N(S)2 series of circuit breakers. It is not intended for use with incompatible switchgear models or for applications outside of the specified electrical parameters. Attempting to use this component with non-matching hardware may result in improper fitment or electrical failure.
Key specifications
- Material: Durable metallic construction
- Compatibility: NZM2, PN2, N(S)2 circuit breakers
- Control circuit terminal capacity: 1x0.75-2.5 mm² (18-14 AWG) or 2x0.75-1.5 mm² (18-16 AWG)
- Configuration: Straight tubular design
- Pole compatibility: 3 or 4 pole switches
How to use
The connector is designed for installation at either the top or bottom terminal of the circuit breaker. Ensure the power supply is disconnected before beginning the installation. Insert the copper conductors into the terminal, ensuring they are properly seated. When using flexible or highly flexible conductors outside the switch housing, it is mandatory to use ferrules to maintain connection integrity. The provided cover must be installed over the terminal to ensure safety and compliance with standard operating procedures.
What to consider before purchase
- Verify compatibility with your specific circuit breaker model (NZM2, PN2, or N(S)2).
- Ensure the conductor cross-section matches the terminal specifications.
- Confirm whether you require a 3-pole or 4-pole configuration.
- Check that the mandatory terminal cover is included and properly fitted during installation.
Usage recommendations
Always adhere to local electrical codes and safety regulations when installing circuit breaker accessories. Ensure that the maximum cross-section limits are respected, especially when using flexible conductors without ferrules, to prevent overheating or connection failure.
