FAQs
IZMX-MIL-3133C-F16-2 is designed for Eaton NRX mechanical interlock installations on NF frame fixed breakers. It supports fixed mounting and integrates with the NRX family, using a 9 in length, 4.5 in width, and 2.25 in height footprint with an 11 lb weight. The UL Listed interlock ensures safe, compliant operation.
Begin by confirming panel compatibility with NF frame fixed breakers. Attach the interlock kit to the breaker using the FIXED mounting method, align the interlock with the breaker handle, and verify positive engagement so the handle cannot move independently. Follow standard Eaton installation practices and consult the accompanying specification sheet for detailed torque and alignment guidance.
This interlock kit is ideal for industrial control panels that require positive interlock action to prevent accidental energizing or de-energizing of NF frame fixed breakers. It is particularly suitable for environments that prioritize safety and reliability within Eaton’s NRX NRX-series lineup, including retrofit projects and new panel builds where consistent interlock behavior is critical.
