The Futaba FUAS0036 is a direct 50A replacement designed for the MC510C electronic speed controller in RC cars. It acts as a sacrificial safety device, interrupting current flow during excessive draw to protect the ESC.
Sold as a maintenance spare without retail packaging, this part restores factory-level overcurrent protection after a blown fuse and is intended for models that call for the MC510C fuse specification.
Fitment involves disconnecting battery power, removing the blown element, and installing the FUAS0036 into the matching inline or panel holder. After installation, run the system at low throttle to confirm correct operation.
