Eaton ES5T1R1RF3 Elevator Control Switch - UL 98 Listed
Part Number: ES5T1R1RF3
Quick Summary
Eaton elevator control switch is a high-amp control device for elevator installations, delivering reliable control and fire safety integration. Engineers often face space constraints and wiring complexity when integrating fire safety interfaces and monitoring relays in centralized control panels. This unit carries UL 98 listing (UL file E182262) and is housed in a rugged NEMA 1 enclosure, with optional neutral lug and a red pilot light for status visibility. By consolidating control, monitoring, and signaling in one enclosure, it reduces panel footprint and simplifies compliance for building services and industrial facilities.

FAQs
The ES5T1R1RF3 is designed for indoor NEMA 1 enclosures with ample space for a control transformer, fire safety interface relay, and terminal blocks. It supports main lugs sized up to (2) #1/0-300 kcmil or (1) #1/0-750 kcmil copper or aluminum, and offers an optional neutral lug. Ensure the panel footprint can accommodate the 54.63 inch height and 25.21 inch width.
Key specs include a 400 A amperage rating and a 480 V nominal voltage rating, plus a 120 Vac coil for the fire safety interface relay. The unit also includes a three-pole fire alarm monitoring relay and a red pilot light for status indication. Verify conductor sizes, protection devices, and compatible control transformers in your elevator circuit.
Yes. The ES5T1R1RF3 combines a fire safety interface relay with a monitoring relay designed for elevator circuits, backed by UL 98 listing. It’s suited for high-rise and critical facilities where fire safety signaling and reliable control are essential, and where a single enclosure can streamline panel design and maintenance.
The unit carries UL 98 listing and UL Listed status (UL file E182262), ensuring compliance for life-safety electrical gear in building systems. The NEMA 1 enclosure provides indoor protection. These certifications support regulatory acceptance in commercial, industrial, and institutional installations and help simplify commissioning and inspections.
Consolidating control, safety interface, and signaling in one enclosure reduces panel complexity, wiring errors, and maintenance time. The red pilot light accelerates fault diagnosis, while UL and enclosure ratings minimize downtime and rework. Although a one-year warranty applies, the integrated design yields lower lifecycle costs through fewer components and reduced space requirements.
