Eaton ES4T2R1RF1NB Elevator Control Switch - UL 98
Part Number: ES4T2R1RF1NB
Quick Summary
Eaton elevator control switch is a rugged 120 Vac coil interface relay designed for elevator control panels in industrial facilities. Too often, integration stalls due to mismatched ratings, insufficient fire-safety interfaces, or bulky enclosures that slow commissioning. UL Listed to UL 98 and built for indoor NEMA 1 service, this unit combines reliability with fire-safety awareness. In practice, engineers gain faster commissioning, safer interlocks, and simplified maintenance with the integrated neutral lug, red pilot indicator, and robust 200 A main switch. This solution supports scalable elevator installations across facilities while meeting stringent electrical safety requirements.

FAQs
Installing the ES4T2R1RF1NB in elevator control panels involves mounting within a NEMA 1 enclosure, wiring the main switch to support up to 208 V, and connecting #6-250 kcmil aluminum or copper lugs for both line and load. The 1NO/NC configuration allows flexible interlock logic, while the 120 Vac coil interface integrates fire-safety control signals. Ensure appropriate clearances and follow manufacturer wiring diagrams for safe commissioning.
Key ratings include a 200 A amperage rating, 208 V voltage rating on the main switch, and a 120 Vac coil for fire-safety interfacing. The 1NO/NC main switch provides versatile control, while the isolated neutral lug enhances safety and reduces interdependence with other control circuits. These specifications support reliable, high-current elevator control in demanding industrial environments.
Yes. The ES4T2R1RF1NB is designed with a 120 Vac coil fire-safety interface relay and a single-pole fire alarm voltage monitoring relay, plus a red pilot light for status indication. Together, these features enable compliant interlocks and rapid fault indication, supporting safety-critical elevator operations and reducing risk during emergency scenarios.
This unit is UL Listed to UL 98 (E182262), signaling compliance with fire-safety and electrical protection standards. The UL listing, combined with a NEMA 1 indoor enclosure, ensures reliable performance in control rooms and equipment spaces. Certification matters for safety audits, warranty eligibility, and code-compliant installation across facilities.
The Eaton ES4T2R1RF1NB is designed for durability in demanding environments, with a robust enclosure and high-current main switch reducing maintenance frequency. The integrated fire-safety interface and visual indicators shorten diagnostic time, while the one-year warranty (or 18 months from shipment) provides a predictable ROI by minimizing downtime and rework in rehabilitation or new-build projects.
