FAQs
The NZMN1-AF25-NA fits within standard three-pole MCCB footprints on the NZM1 frame, with dimensions of 2.68 in depth, 3.75 in height, and 3.54 in width. Its 25 A rating and 50 kAIC interrupt capacity support dense panel layouts while maintaining adequate clearance for wiring. Use the rocker lever for ergonomic operation and ensure torque specs meet Eaton mounting guidelines to maintain performance and clearance for future maintenance.
This device is a three-pole molded case circuit breaker with a 25 A rating, designed for 690 Vac and 500 Vdc. It employs a thermal-magnetic trip (T268) and provides a 50 kAIC interrupt rating. The NZMN1 frame and NZM1 series design support distribution protection, making it suitable for reliable protection of three-phase circuits in industrial environments.
Yes. The NZMN1-AF25-NA is UL Listed, IEC Rated, and CSA Certified, which supports regulatory compliance across major markets. This combination helps simplify audits and ensures that the device can be sourced and deployed in multinational projects without compromising safety or performance standards.
A 50 kAIC interrupt rating means the breaker can safely interrupt high fault currents without internal damage, reducing the risk of collateral equipment damage and expensive downtime. For design, this rating supports coordination with upstream devices and ensures rapid fault clearance in industrial power distributions, particularly where fault currents can surge during startup or switching events.
Using the NZMN1-AF25-NA delivers dependable protection, standardization with Eaton’s NZM1 family, and broad certifications for global deployment. The compact form factor saves panel space, while the 25 A rating and 690 Vac / 500 Vdc capability align with common manufacturing workloads. This translates to lower maintenance costs, reduced downtime, and streamlined procurement through a familiar, supported protection platform.
