Century Motors H841V1 Motor

The Century Motors H841V1 Motor serves as the industry-standard, high-performance direct replacement for H481, engineered specifically for high-demand HVAC belt drive blower systems. This 3/4 HP three-phase motor features a robust M56 frame and an Open Drip Proof (ODP) enclosure, ensuring optimal airflow and cooling in relatively clean environments. Operating at a high-speed 3450 RPM, it utilizes ball bearings for reduced friction and extended duty cycles. The 5/8" x 5/8" keyed shaft and cradle base mounting provide a stable, standard fit for multi-stage commercial blowers and ventilators. With dual voltage 460/200-230Vac capability and a 1.50 service factor, this reversible rotation motor adapts to varied electrical loads without compromising performance. Designed with automatic overload protection and Class B insulation, it remains a reliable choice for technical professionals requiring precision three-phase induction motor specs and NEMA 56 frame compatibility.
