FAQs
Begin by powering down the panel and disconnecting sources. Remove the existing release, verify mounting points on the universal NRX frame, and align the IZMX-SR60DC-1 with the PXR-compatible footprint. Securely fasten, connect any required leads per Eaton wiring diagrams, and perform a controlled release test to confirm proper operation before returning the panel to service.
The kit is a 60 V DC spring release assembly rated for 60 V DC with a 50 to 60 Hz frequency range. It is cataloged as Type 60 Vdc Spring Release Assy Kit and carries UL Listed certification, supporting safe operation in standard control circuits and protection schemes within industrial environments.
Yes. IZMX-SR60DC-1 is designed for 60 V DC control circuits and is UL Listed, which helps meet safety and compliance requirements for industrial protection and interlock applications in control panels, robotics cells, and conveyors where reliable spring-release action is critical.
Maintenance considerations include scheduled checks for release reliability, post-trip inspection, and ensuring the universal NRX frame mounting remains secure. The kit’s spring-release design supports repeatable actuation, reducing variability and downtime. Always use Eaton wiring diagrams for field wiring and replace only with IZMX-SR60DC-1 to preserve compatibility and UL compliance.
Upgrading to NRX spring release kits improves trip accuracy, reduces nuisance trips, and shortens maintenance cycles, leading to less downtime and lower service costs. The universal NRX frame compatibility streamlines procurement and retrofit work, while UL Listed certification provides confidence during audits and regulatory reviews for control-system protection in automation environments.
