Industrial ECP3661T

The Baldor-Reliance ECP3661T is a rugged 3 HP, 1,755 RPM, 3‑phase motor designed for continuous duty in severe environments, featuring a TEFC enclosure and a cast‑iron 182T frame for maximum durability. It operates on 208–230/460 V at 60 Hz, with current draws of about 8.6 A at 208 V, 8.2 A at 230 V, and 4.1 A at 460 V, and it delivers an efficiency of 89.5% at full load with a power factor around 0.77. The motor is built for hazardous locations (Class/Group CLI GP A,B,C,D; Division II) and carries agency approvals including NEMA Premium, UR, CSA EEV, and CSA US. An ambient temperature rating of 40 °C, Polyrex EM bearing grease, and a rigid base contribute to its robust, maintenance‑friendly design; there is no auxiliary box or drip cover. The ECP3661T lists a ship weight of approximately 110 lb and a nominal synchronous speed of 1,800 RPM (running speed typically near 1,755 RPM), aligning with direct‑on‑line starting for this continuous‑duty motor. In performance terms, it provides a break‑down torque around 33.1 LB‑FT, a pull‑up torque near 18.2 LB‑FT, and a locked‑rotor torque of about 20.4 LB‑FT, making it suitable for demanding loads that require reliable torque at start and steady operation.
