Key Features
- Genuine OEM Electrical Spec — Matched to the original trip current threshold and button actuation force of the WM900/EC900 motor protection circuit, so it responds exactly as the factory-designed reset should.
- Drop-In Installation — Mounts directly into the existing control panel housing on WM900 series mixers without modification to wiring or mounting hardware.
- Confirmed WM900 Fitment — Verified for WM900 concrete mixer models, eliminating compatibility risk when ordering.
- Restores Full Motor Protection — A properly functioning reset button allows the overload protection circuit to do its job, protecting the mixer motor from damage caused by overloads or thermal events.
- Electrical Safety Compliance — Using the correct OEM reset button ensures the overload circuit operates within its intended parameters, which is critical for operator safety and proper motor cutoff behavior.
The reset button on a WM900 or EC900 concrete mixer is the manual interface for the motor overload protection circuit. When the mixer motor draws excessive current — due to an overloaded drum, stalled rotation, or a thermal event — the overload relay trips and interrupts power to protect the motor from burnout. The reset button allows the operator to manually restore the circuit once the cause of the overload has been resolved. A worn, broken, or incorrect reset button can prevent the circuit from resetting properly or, in some cases, compromise the overload protection function entirely, leaving the motor vulnerable to damage.
