FAQs
Yes. The RL1310A277 is designed around frame size 56/56H with a resilient base, enabling straightforward horizontal or vertical mounting. It supports direct-on-line starting and 277 V operation, making it a practical replacement for older 56 frame motors in control panels and ventilation housings, while maintaining alignment with NEMA design standards.
Key specs include 1 phase, 277 V, 60 Hz operation, 1725 rpm synchronous speed, and a rated current of 5.4 A. The motor provides 1 HP output with an insulation class of F and an efficiency of about 70%. These figures support predictable fan performance and stable enclosure cooling under continuous duty.
Ideal for industrial controls, process equipment ventilation, and open-enclosure cooling tasks. Its 1 HP rating and 1725 rpm speed suit moderate airflow requirements in manufacturing lines, data centers, and HVAC housings, where compact form factor and resilient mounting simplify retrofits and new installs alike.
The RL1310A277 carries CSA/UR certification and RoHS compliance, with a NEMA design classification (L). These credentials help meet safety, environmental, and industry-standard requirements for heavy-duty equipment in North American facilities.
With regreasable bearings and a robust 56/56H frame, maintenance intervals can be extended when properly serviced. The motor is stocked at multiple warehouses with 0 day lead time, reducing downtime and improving return on investment by enabling rapid replacements and predictable inventory planning.
