FAQs
The ES4T1R2RNB is designed for standard DIN rail installation. Verify rail type (TS-35 commonly), ensure proper rail alignment for secure snap-in mounting, and leave adequate clearance for wiring and cooling. Confirm compatible enclosure width and ensure the device is seated firmly to prevent micro-movement that can affect contacts over time.
The ES4T1R2RNB provides reliable overcurrent protection with clear status indications to aid quick fault isolation. It supports selective coordination within panel protection schemes, helping reduce nuisance trips and maintain critical machine functions during fault events.
Yes. This model is intended for industrial protection roles in control panels used across packaging and manufacturing lines. Its compact footprint, DIN-rail mounting, and straightforward diagnostics make it well suited for high-density panels and rapid line changes typically required by OEMs and integrators.
The ES4T1R2RNB aligns with common safety and IP-related considerations in industrial installations. In practice, CE safety compliance and appropriate enclosure IP ratings support regulatory adherence and ingress protection for typical factory environments; SIL readiness may apply in safety-related configurations within larger protection schemes.
The device’s robust design and diagnostics reduce unscheduled downtime and simplify fault finding, translating to lower maintenance costs. Its compatibility with existing Eaton components minimizes spare-part diversity, while quick deployment and predictable performance shorten project timelines, delivering measurable total cost of ownership improvements.
