Eaton ES4T4R1B Elevator Control Switch - UL 98 Listed

Feature → Business Impact → Application: The ES4T4R1B employs a 120 VAC coil fire safety interface relay, enabling integrated fire safety interlock operations that minimize risk during emergency shutoffs. This reduces downtime and enhances occupant protection in elevator systems, particularly in facilities requiring rapid response and reliable control signaling in fire events. The 200 A, 600 V rating supports heavy-duty load switching, improving system reliability in high-demand elevator installations and minimizing nuisance trips in demanding commercial environments.Feature → Business Impact → Application: A NEMA 1 enclosure and heavy-gauge terminals with #6-250 kcmil Al/Cu main lug support easy, field-friendly wiring and durable enclosure integrity. This translates to simpler installation, faster commissioning, and lower field wiring costs, especially in retrofits where space and access can be constrained. The design also aligns with standard industry practices for elevator control cabinets and control power transformers, ensuring compatibility with existing panels.Feature → Business Impact → Application: The 1NO/NC main switch configuration provides flexible control logic for start/stop commands and fault signaling, improving safety interlocking and ensuring predictable operation in both new installations and service upgrades. Combined with UL 98 and UL 182262 certification, this supports regulatory compliance and reduces risk during audits, aiding procurement in highly regulated environments.Feature → Business Impact → Application: Class J fuses are not included, allowing system integrators to choose protection schemes that align with site-specific safety strategies, which can reduce inventory and simplify maintenance. With a standard oversize enclosure to mount control transformers and terminal blocks, the ES4T4R1B offers installation efficiency and scalable future upgrades in elevator control rooms.Feature → Business Impact → Application: The device’s compatibility with common low-voltage and control wiring practices makes it suitable for retrofit projects where existing feeders, lugs, and interlocks must be preserved. This reduces project risk and shortens lead times, while ensuring the elevator control switch remains compliant with current electrical codes and industry standards.
