FAQs
The ES5T2R1GF3B is designed for a NEMA 1 enclosure and heavy-duty main wiring. It supports (2) #1/0-300 kcmil or (1) #1/0-750 kcmil aluminum or copper conductors and uses a 208 V main circuit with a 120 V coil. Plan room for mounting, allow space for the 400 A capacity, and consider optional neutral lug sizing for balance in specific installations.
Yes. The device is rated for 208 V main circuits and features a 120 V coil control. It also includes a 1NO/NC main switch, enabling flexible control logic and easy integration with existing elevator control schemes, reducing rework during retrofits and facilitating compliant, reliable operation.
The ES5T2R1GF3B carries UL Listed status under E182262 and UL 98, indicating compliance with key safety standards for elevator control equipment. These certifications support code compliance during inspections and help reduce qualification time for new builds and modernization projects.
Main lug connections accommodate (2) #1/0-300 kcmil or (1) #1/0-750 kcmil aluminum or copper conductors, enabling flexible feeder sizing and easier field termination. This reduces inventory complexity and supports efficient panel expansion or upgrades without extensive rewiring.
By combining a fire safety interface relay, a three-pole monitoring relay, and a green pilot light within a UL-listed, NEMA 1 enclosure, the unit enhances safety signaling and fault visibility while reducing downtime. The strong amperage and voltage ratings support reliable operation under load, delivering faster ROI through lower maintenance costs and fewer unscheduled shutdowns.
