Eaton ES4T3R2RF1 Elevator Control Switch - UL 98 Listed
Part Number: ES4T3R2RF1
Quick Summary
The Eaton elevator control switch is a critical device for safely coordinating elevator control circuits in commercial and industrial facilities. Engineers often struggle with ensuring reliable fire-safety interfaces and voltage monitoring without complicating installation or increasing downtime. This module carries UL 98 listed safety certification and UL Listed status under E182262, with a rugged NEMA 1 enclosure for harsh environments. In practice, the combination of 24 Vdc coil fire safety interface relay, 200 A at 240 V, and a compact control power transformer supports faster commissioning while maintaining compliance. By reducing wiring complexity and boosting reliability, it lowers maintenance costs and supports safer elevator operations across multiple sites.

FAQs
To install ES4T3R2RF1, ensure a NEMA 1 enclosure is used and the main power wiring accepts #6-250 kcmil Al/Cu lugs. Verify 24 Vdc coil operation and connect the red pilot light for status indication. Confirm compatibility with existing fire-safety interfaces and single-pole fire alarm monitoring relays. Review the oversize enclosure notes to allocate space for the control transformer and terminal blocks, then perform a standard UL 98 compliance check during commissioning.
The 24 Vdc coil fire safety interface relay provides a dedicated, low-voltage control path for fire-related signals, isolating safety logic from higher-power elevator circuits. This separation reduces risk of false trips and electrical interference, improving signal integrity. In practice, engineers can rely on consistent voltage monitoring for fire alarm circuits and predictable actuation of the elevator control switch, which translates to lower downtime and safer operation.
Yes, ES4T3R2RF1 is suitable for high-rise and large-building applications where high current and robust protection are required. Its 200 A at 240 V rating supports substantial elevator loads, while the NEMA 1 enclosure and UL 98 listing ensure safe integration within utility rooms and machine spaces. The unit’s 11.28 in depth and 20.38 in width enable installation in standard control panels without sacrificing spare space for transformers or terminal blocks.
The ES4T3R2RF1 carries UL 98 listing and UL Listed status under file E182262, providing recognized safety validation for elevator control switch assemblies. These certifications matter because they reduce regulatory risk, support audit readiness, and simplify procurement for facilities subject to strict electrical safety standards. The combination of UL certification with a NEMA 1 enclosure further reinforces suitability for demanding building environments.
Maintenance benefits arise from the switch’s straightforward wiring, visible status indicator (red pilot light), and modular enclosure that accommodates control transformers and terminal blocks. ROI is achieved through improved system uptime, reduced wiring errors, and faster commissioning thanks to the oversize enclosure design. Coupled with UL-listed safety and durable construction, the ES4T3R2RF1 helps lower long-term maintenance costs in elevator safety systems.
