Tunnel terminals 3-pole 1 for outside NZM1-XKA circuit breaker 266730

Tunnel terminals for NZM circuit breakers – reliable connection and safety

The 3-pole NZM1-XKA tunnel terminal (cat. no. 266730) is a dedicated accessory for the NZM series circuit breakers, providing a solid and safe connection of wires. This is a key element for installers and users who value reliability and ease of installation in electrical systems. Compatible with PN1 and N(S)1 circuit breakers, it offers versatility in various configurations.

Design and installation – simplicity for professionals

The tunnel terminal is designed for quick and intuitive installation. Installation takes place outside the circuit breaker housing, which facilitates access and minimizes the space required to connect the wires. The set includes a control cable with a cross-section of 0.75-2.5mm² (18-14 AWG) or 2x0.75-1.5mm² (18-14 AWG), eliminating the need for additional purchases. An NZM1(-4)-XKSA cover (included) is required, which provides additional safety and aesthetics of the connection. When working with stranded or very flexible wires, it is recommended to use crimp ferrules for optimal connection durability.

Versatility and compatibility – one terminal, many possibilities

This tunnel terminal is part of a wide range of accessories compatible with both LZM/LN and NZM/N series circuit breakers, making it an economical choice for investing in electrical infrastructure. This means that one solution can be used in different projects, reducing storage and spare parts ordering costs. This terminal allows connecting wires to circuit breakers with rated currents up to 160A, providing flexibility in selecting components for specific application needs.
