EATON Circuit Breaker Accessories – Expanding Possibilities

The drive shaft extension, dedicated to the NZM series circuit breakers, is a practical solution allowing for flexible mounting and operation of devices. Compatible with NZM1(-4), PN1(-4), N(S)1(-4), NZM2(-4), PN2(-4) and N(S)2(-4) models, it enables adaptation of the circuit breaker to specific installation conditions. Thanks to it, operating the circuit breaker becomes more convenient, especially in hard-to-reach places or when using deeper control cabinets.

Application and compatibility

This drive shaft extension is part of a wide range of EATON accessories, designed to optimize the functionality of LZM/LN and NZM/N circuit breakers. It allows maintaining full electrical efficiency up to a temperature of 50°C. Its main task is to extend the drive shaft, which facilitates operation of the circuit breaker, especially in situations where the standard shaft length is insufficient. The maximum mounting depth using this extension is 400 mm.

Construction and parameters

Made of high-quality materials, the extension is characterized by a solid construction and reliability. Its cross-section with dimensions of 8 mm x 8 mm ensures adequate mechanical strength and stability. The length of 290 mm allows for a significant extension of the drive shaft, giving greater freedom in arranging space in the control cabinet. This solution will be appreciated by both installers and end-users who value functionality and ease of use.
