FAQs
The IZMX-MIL-2C-W40-2 mechanical interlock is designed for Eaton NRX series Drawout breakers within RF-frame enclosures, providing reliable interlock function in electrical protection and circuit control applications. It is especially beneficial for control panels and power distribution cabinets where safe, sequential operation is essential, and where Type 2 Cable configurations are standard. Its integration supports safer maintenance practices and quicker retrofit deployments, reducing overall project risk.
Yes, IZMX-MIL-2C-W40-2 is UL Listed. This designation indicates compliance with recognized safety standards for electrical interlocks, simplifying regulatory audits and supplier qualification. For facilities pursuing formal safety compliance and insurance alignment, UL Listed interlocks help mitigate risk during switching and maintenance, ensuring that the interlock installation meets industry safety expectations.
The interlock uses DRAWOUT mounting and is compatible with the RF frame Drawout breakers in NRX panels. For installation, align the interlock with the breaker handle and panel frame, secure per Eaton’s guidelines, and verify correct engagement to prevent energization during withdrawal. This design supports straightforward retrofits and minimizes panel downtime, especially in facilities with frequent maintenance cycles.
A mechanical interlock provides tangible safety gains by physically preventing the breaker from being withdrawn or re-energized while the circuit is open or in a controlled state. This reduces arc flash risk, misoperation potential, and unplanned downtime. For NRX panels, the IZMX-MIL-2C-W40-2 ensures consistent operation with RF-frame equipment, simplifying training and lowering maintenance costs over the asset lifecycle.
This interlock kit carries a one-year factory warranty issued from the date of shipment from Eaton’s repair center, reflecting confidence in its reliability for industrial environments. Technical support and replacement parts are available through Eaton’s channel partners, helping maintain uptime, expedite maintenance tasks, and ensure continued compliance with safety standards.
