Eaton ES5T2R1GF3 Elevator Control Switch - UL 98
Part Number: ES5T2R1GF3
Quick Summary
Eaton elevator control switch ES5T2R1GF3 is a robust solution for integrating fire-safety monitoring with elevator control in industrial facilities. It combines a 120 Vac coil fire-safety interface relay with a three-pole fire alarm voltage monitor, a green pilot light, and a 400 A main rating in a NEMA 1 enclosure. This design reduces panel complexity by uniting control power, safety interlocks, and status indication. A common challenge is meeting UL 98 requirements while accommodating large conductor sizes in limited space. UL Listed (file E182262) confirms code compliance, and the oversize enclosure supports mounting transformers and terminal blocks. For engineers, the result is reliable operation, straightforward installation, and a clear path to ongoing maintenance.

FAQs
Plan for a NEMA 1 enclosure sized to accommodate a control transformer, the fire safety interface relay, and control terminal blocks as noted in the catalog notes. Use the main lug wiring specification of (2) #1/0-300 kcmil or (1) #1/0-750 kcmil Al/Cu, and note that Class J fuses are not included. The 120 Vac coil and 208 V main rating support 400 A service with UL 98 compliance.
Key specs include a 120 Vac coil, 208 V voltage rating for the main, and a 400 A amperage rating. The main lug wiring accepts (2) #1/0-300 kcmil or (1) #1/0-750 kcmil aluminum or copper conductors. It uses a NEMA 1 enclosure, green pilot light, and UL 98 certification with UL Listed file E182262.
Yes. The ES5T2R1GF3 is UL 98 listed and UL Listed (file E182262), ensuring compliance for elevator control panels and safety interlocks. This certification supports code adherence in commercial and industrial environments when paired with the NEMA 1 enclosure and proper wiring practices.
It integrates a 120 Vac coil fire safety interface relay with a three-pole fire alarm monitor and a green status pilot light, simplifying interlocks between building safety systems and elevator control. The design supports large conductor sizes, is UL certified, and fits in an oversize NEMA 1 enclosure to streamline installation and maintenance.
