Berko 3900-2002-506 Motor

The Berko 3900-2002-506 is a specialized 208V 2-speed motor engineered specifically for compatibility with select Berko and QMark electric heater assemblies. Designed for heavy-duty commercial and industrial air handling, this direct drive motor ensures consistent airflow across heating elements to maintain optimal heat exchange and prevent thermal overload cycles. Operating at 208 Volts, this OEM replacement component features a multi-speed configuration, allowing technicians to calibrate system performance based on required CFM and static pressure requirements. The motor's construction focuses on high-temperature resilience and long-term mechanical reliability in demanding environments. When performing a field replacement, verify the shaft diameter and mounting pattern against the existing bracketry to ensure a drop-in fit. Integrating OEM Berko parts like the 3900-2002-506 preserves the original equipment's UL listing and ensures the internal thermostatic controls interface correctly with the motor’s amperage draw.

• Dual-Speed Logic: Provides flexible airflow management for varying heating demands in commercial spaces.
• OEM Precision: Guaranteed electrical compatibility with Marley Engineered Products heating units.
• Industrial Build: Rated for high-cycle operation and engineered to withstand the ambient heat of electric furnace cabinets.
• Standardized Voltage: Specifically wound for 208V single-phase circuits, common in commercial distribution.

Is the Berko 3900-2002-506 compatible with 240V systems?
This specific motor is rated for 208V operation. While some heating equipment is rated 208/240V, always verify the motor nameplate and control circuit requirements before installation.

What are the wiring positions for the 2-speed configuration?
Technicians should refer to the original unit's wiring diagram, as lead colors on the 3900-2002-506 correspond to specific high and low speed taps regulated by the unit’s internal switchgear.

Does this motor include the fan blade or blower wheel?
This item is the motor only. It features a standard shaft design to accept existing hub-mounted fan blades or blowers.
