Wacker Neuson 5000128335 12V/40A Relay

The Wacker Neuson 12V/40A Relay is a genuine OEM electrical relay designed for the BFS 2575KLS Floor Saw and DFS 2075HLS Diesel Walk-behind Saw. As a direct factory replacement, this relay is manufactured to the exact voltage and amperage specifications required by the machine's electrical system, ensuring proper circuit switching without the risk of mismatched ratings. Sourcing a genuine OEM component means you're getting the same part that left the factory — no guesswork on compatibility or electrical tolerances. Keep part number on hand as a service item, particularly during scheduled electrical system maintenance or when diagnosing ignition and control circuit faults.

Key Features

• Matched Electrical Rating — Rated at 12V/40A to meet the precise switching demands of the saw's control circuit, preventing over-current faults or relay chatter caused by undersized substitutes.
• Genuine OEM Component — Sourced directly from Wacker Neuson and manufactured to the same specification as the original relay installed at the factory.
• Direct Plug-in Replacement — Designed to seat into the existing relay socket on compatible saws, using the same terminal configuration as the factory-installed unit.
• Confirmed Fitment — Compatible with the BFS 2575KLS Floor Saw and DFS 2075HLS Diesel Walk-behind Saw.
• Electrical System Integrity — A correctly functioning relay ensures clean, reliable switching of high-current circuits; a failed relay can prevent the machine from starting or cause erratic control behavior mid-cut.
• Electrical Safety Compliance — Using a correctly rated OEM relay ensures the switching circuit operates within its designed load limits, reducing the risk of heat buildup or arcing in the relay socket.

A relay is an electrically controlled switch that allows a low-current signal — such as one from a control switch or ignition circuit — to safely activate a higher-current load circuit, like a starter motor or fuel shutoff solenoid. In floor saws like the BFS 2575KLS and DFS 2075HLS, the relay acts as a gatekeeper for critical electrical functions, and a failed or degraded relay can cause hard starting, intermittent shutdowns, or complete loss of machine function. Replacing a faulty relay with the correct OEM-rated unit restores full electrical control and prevents collateral damage to connected components.
