FAQs
The interlock is designed for DRAWOUT mounting on NF frame NRX drawout circuit breakers. It ships as a mechanical interlock kit and installs alongside the NRX assembly, ensuring the correct sequencing and preventing interchanged breakers. For installation, align with the NRX interlock mounting points, secure the kit to the breaker assembly, and verify the interlock engages with the drawn-out breaker. This minimizes misoperation and streamlines commissioning in control panels.
