Eaton Specification Sheet - ES4T2R1WF3
UL Listed and UL 98 certified construction delivers safety compliance and code readiness across facilities. The ES4T2R1WF3’s UL E182262/UL 98 certifications provide traceable safety performance for fire-safety interfaces and voltage monitoring relays. In practice, engineers can specify this unit with confidence, knowing it aligns with established standards while supporting fast procurement. With a 200 A amperage rating and a 208 V voltage rating, the switch handles demanding elevator circuits without overheating or nuisance tripping. This capacity translates to fewer control-device upgrades during system expansions and improved reliability in peak-load scenarios. The 120 VAC coil fire-safety interface relay paired with a three-pole fire alarm voltage monitoring relay streamlines integration with existing fire alarm and safety networks. White pilot light provides at-a-glance status in control rooms, while the no-neutral-lug option reduces installation complexity in legacy wiring schemes. Designed for interior use in a standard oversize enclosure, the unit accommodates control power transformers and terminal blocks within a single, rugged NEMA 1 cabinet. The enclosure and layout support straightforward mounting of #6-250 kcmil aluminum or copper conductors, easing field wiring and future modifications. Compatibility with large conductor sizes and clear catalog notes help avoid last-minute substitutions during commissioning, saving time and labor costs. By consolidating fire-safety interface, voltage monitoring, and elevator control in one device, maintenance teams experience lower spares inventory and faster fault diagnosis.

FAQs
For retrofits, plan a NEMA 1 enclosure with sufficient space for the fire-safety interface relay and control terminal blocks. Use #6-250 kcmil Al/Cu conductors and verify the oversize enclosure allowance noted in the catalog. Align wiring with the 120 VAC coil and 208 V main supply to minimize field rewiring and reduce installation risk.
Designers can size feeders and protective devices around the 200 A ampacity and 208 V system voltage, ensuring the elevator control switch handles peak loads without nuisance trips. The 120 VAC coil facilitates integration with standard fire-safety circuits, while maintaining margin for future expansion. This helps avoid costly rewiring and supports reliable operation in high-demand environments.
Yes. The ES4T2R1WF3 is UL Listed (E182262) and UL 98 compliant, providing documented safety certification for fire-safety interface and enclosure performance. Supporting datasheets and catalog notes are available, including the Eaton specification sheet and UL/CSA cross-reference, to aid qualification and audit readiness. Ask for the official UL listing report and the E182262 certificate package for compliance reviews.
Yes, it supports main lug sizes up to #6-250 kcmil Al/Cu, enabling robust power connections for heavy elevator loads. The catalog notes also indicate an optional neutral lug size equal to line and load, which can simplify integration when a neutral path is required. This reduces field changes and supports flexible wiring schemes in new-build and retrofit projects.
Routine inspection of the NEMA 1 enclosure and pilot light feedback, plus periodic verification of the fire-safety interface relay operation and voltage monitoring relay, keeps fault signaling reliable. ROI comes from reduced downtime, faster commissioning, and fewer substitutions during upgrades due to the integrated design and high-load capacity. This translates to measurable savings over the system life cycle.
