FAQs
To install IZMX-AS22-40-1 with NRX frames, begin by confirming panel compatibility and power ratings for the NRX protection circuit. Mount the RF frame and connect the PXR auxiliary switch to the designated control terminals. Use the Long Leads Kit if extending signaling paths to remote locations, then verify integrity with UL-listed wiring practices. Finally, perform a functional check to confirm correct signaling and fault indication under normal and fault conditions. This sequence minimizes wiring errors and expedites commissioning.
The PXR auxiliary switch offers a dedicated contact set for signaling that reduces cross-wiring and improves fault visibility in ICCB configurations. It supports faster diagnostics, shorter troubleshooting times, and safer panel operation by providing a clear, isolated signal path. When combined with the NRX frame, it enhances control reliability in motor protection schemes and contributes to higher overall system uptime.
Yes. IZMX-AS22-40-1 is designed as a PXR auxiliary switch for use with Eaton NRX protection frames and RF frames. It integrates with the NRX family to deliver extended signaling capabilities via the Long Leads Kit option, enabling flexible installation in crowded control cabinets. This compatibility simplifies part replacement and ensures consistent behavior within existing Eaton protection architectures.
IZMX-AS22-40-1 carries UL Listed certification, indicating compliance with recognized safety standards for electrical control components. This certification helps ensure safe operation in industrial panels, reduces risk during maintenance, and supports compliance during audits. While additional certifications may be site-specific, UL Listed status is a robust baseline for reliability in commercial and industrial environments.
The auxiliary switch reduces wiring complexity and accelerates commissioning, leading to lower labor costs during installation and upgrades. Its dedicated signaling path improves fault diagnostics, shortening downtime during maintenance. Over the life of a protection system, this translates to higher asset availability, fewer re-wiring errors, and a lower total cost of ownership when deployed within NRX-based protection schemes.
