Contactor 3740073 | JLG Aerial Lift Parts

The 3740073 is a 24 V 200 A contactor (solenoid relay) used in JLG aerial work platforms. It functions as a heavy‑duty relay that switches high‑current power to major electrical loads like the drive motor and other drive‑related circuits. By reliably connecting and disconnecting high electrical currents based on signals from the control system, it helps ensure smooth traction performance and protects the electrical system from overloads.

This contactor is designed for industrial use in mobile elevating work platforms and is typically installed within the machine’s main power distribution panel or electrical control assembly.
