Eaton NZMN1-A20 NZM complete MCCB - UL Listed

With a 20 A amperage rating and a voltage window of 690 Vac / 500 Vdc, the NZMN1-A20 covers both AC and DC distribution networks. This versatility reduces the need for multiple device variants, simplifying procurement, stocking, and future expansion across mixed-panel environments. Designed around the NZM1 frame, the breaker integrates cleanly into standard distribution panels, motor control centers, and switchgear housings. The compact form supports tighter layouts without compromising protection reliability, which is a meaningful savings during retrofits. A 50 kAIC short-circuit breaking capacity paired with a thermal-magnetic T268 trip ensures rapid fault isolation and limited arc energy. Users benefit from higher equipment availability and reduced risk of collateral damage in upstream gear. In practice, this performance is valuable in manufacturing lines, pumps stations, and data-center enclosures where uptime is critical. The device's three-pole construction reinforces coordinated protection across three phases, enabling safer startup sequences. Front-frame clamp connections simplify mounting and allow quick, secure field installation with minimal hardware. A rocker-lever operator supports fast manual operation and straightforward maintenance in busy control rooms. The adjustable setting range of 15-20 A gives precise overload protection tuned to each load. These features together reduce wiring complexity and improve consistency during panel commissioning. UL Listed certification confirms compliance with recognized safety standards, helping to streamline audits and approvals. Eaton's standard warranty provides one year from installation or eighteen months from shipment, whichever comes first. Region-specific requirements, such as CE or other market marks, should be confirmed with Eaton for your installation. This proactive support minimizes risk and supports a predictable maintenance plan. Across legacy upgrades and new-build projects, the NZMN1-A20 delivers consistent protection for mixed voltages and varying loads. Its reliability, installation efficiency, and documented performance translate into measurable ROI through reduced downtime. Industry teams value the standardized Eaton design for faster integration with existing panels and spare-part availability. Together, these factors support lower total cost of ownership and longer asset life in critical facilities.
