Eaton Specification Sheet - ES4T3R1RF3B
Selling Policy 25-000 - Distribution and Control Products and Services
High-current capability meets 200 A at 240 V, reducing panel wiring complexity and potential contact fatigue while enabling direct control of elevator main circuits; this cuts installation time and long-term maintenance costs in large facilities. The 120 Vac coil fire-safety interface relay improves interoperability with building safety systems, delivering faster, safer responses during emergencies and simplifying overall system integration. A three-pole fire alarm voltage monitoring relay provides robust fault signaling with reduced false trips, supporting reliable operation in high-rise installations. A red pilot light offers immediate status visibility, accelerating troubleshooting and minimizing downtime in critical elevator bays. The enclosure is a rugged NEMA 1, with main lug wires sized up to #6-250 kcmil Al/Cu, enabling straightforward retrofits and scalable wiring for transformer connections. UL 98 certification and UL Listed status confirm compliance, lowering validation risk and speeding code approvals for commercial projects. Catalog notes indicate the system is designed for standard oversize installations and transformer terminations, with an optional neutral lug to match line and load needs.

FAQs
The ES4T3R1RF3B is designed for direct integration in standard elevator control panels with a 200 A, 240 V main circuit and 1NO/NC main switch. It uses a NEMA 1 enclosure and accepts #6-250 kcmil aluminum or copper conductors for main lugs, simplifying retrofits while preserving existing control architectures and safety interlocks.
This Eaton switch carries UL 98 certification and UL Listed status (file E182262), confirming compliance with recognized safety standards for elevator equipment. These certifications help shorten validation time with authorities having jurisdiction, reduce risk in regulated environments, and reassure building owners and maintenance teams about performance under normal and fault conditions.
Plan for a NEMA 1 enclosure sized to house the control transformer, fire-safety interface relay, and terminal blocks. The device supports mains up to 200 A at 240 V, with main lug wiring up to #6-250 kcmil Al/Cu. Dimension references (approx. 11.28 in L, 32.63 in H, 20.38 in W) and a weight of about 76 lb should be accounted for in panel layouts and mounting considerations.
The unit includes a 120 Vac coil fire-safety interface relay and a three-pole fire alarm voltage monitoring relay, enabling integrated signaling to fire-safety systems and redundant fault detection. This reduces external wiring, speeds deployment, and lowers the risk of miscommunication between elevator controls and building safety networks in critical environments.
Eaton offers a one-year limited warranty from installation or eighteen months from shipment, whichever occurs first, as per policy 25-000. In addition to the warranty, you gain access to Eaton's technical support and service resources, ensuring assistance during commissioning, maintenance planning, and any required safety audits for elevator applications.
