Frequently Asked Questions

Q: What is the 3BA-47-A4170 contactor and what equipment does it fit?
A: The 3BA-47-A4170 is a 24 Volt, 150 Amp DPDT (double-pole double-throw) contactor designed for electric lift truck traction control circuits. This OEM-grade replacement part is compatible with EV100-series electric pallet jacks and sit-down rider forklifts from manufacturers including Crown, Toyota, Raymond, Yale, Hyster, and similar brands that use 24VDC forward/reverse control systems.

Q: What are the electrical specifications of this contactor?
A: Operating voltage is 24VDC. Rated continuous current is 150 amps. The contactor features a continuous-duty coil suitable for repeated duty cycles in lift truck applications. Silver alloy contact tips are 0.290 inch diameter, designed for reliable switching in high-current EV100 traction circuits.

Q: What material are the contact tips and why does that matter?
A: Contact tips are silver alloy, which provides superior arc resistance, conductivity, and durability compared to standard brass tips. This material choice minimizes contact wear during forward/reverse switching cycles and maintains consistent electrical performance over the life of the contactor in continuous-duty material handling applications.

Q: How is this contactor mounted in the truck circuit?
A: The 3BA-47-A4170 features an integral bracket mount, allowing direct installation in standard lift truck electrical enclosures. The mounting design is compatible with OEM backplates and motor control modules found in EV100-series equipment.

Q: Is there a cross-reference or OEM part number for this contactor?
A: This part is referenced as both 3BA-47-A4170 and AC3BA-47-A4170 in manufacturer documentation. Verify the exact part number matches your equipment before ordering to ensure proper fitment and voltage compatibility.
