The Husqvarna 578373201 Electronic Box is a genuine OEM component designed for the WS440HF, WS440, WS482, and WS442 wall saws. As an authentic Husqvarna replacement, this part is manufactured to the same specifications as the original, ensuring the saw's electronic control system operates exactly as engineered. DHS Equipment supplies this part to help keep your wall saw running at full capability.
Key Features
- OEM-Matched Control Electronics — Built to Husqvarna's original circuit and output specifications, so the control system responds and communicates with the saw's components exactly as intended from the factory.
- Direct-Fit Replacement — Engineered to mount and connect using the same housing geometry and wiring interface as the original unit, allowing straightforward installation on compatible wall saws.
- Broad Wall Saw Compatibility — Confirmed fitment across the WS440HF, WS440, WS482, and WS442 track-mounted wall saws, covering multiple configurations within the WS series.
- Restored Machine Control — A functioning electronic box is essential for consistent motor speed regulation, blade tracking, and operator command response; replacing a failed unit restores full operational control of the saw.
- Electrical Safety Assurance — Using a genuine OEM electronic box ensures the control circuitry meets Husqvarna's safety and EMC standards, reducing the risk of erratic behavior or electrical faults during high-load cutting operations.
The electronic box is the central control unit that manages power delivery and operational commands on Husqvarna WS series wall saws. It processes input signals from the operator controls and regulates the saw's motor output accordingly, keeping blade speed and cutting performance consistent throughout the cut. When this component fails or becomes damaged, the saw may lose responsiveness, behave erratically, or shut down entirely — making prompt replacement with a correctly specified unit critical to safe and productive operation.
