Conventional Overload protection is not at all suitable for Blower / Fans due to their starting characteristic. Diligent Unique Protector for Blower / Fan is really unique. It allows normal blower start up successfully; however, if blower motor draws more current than set limit, it immediately trips the motor. This is very useful as blower / fan is most ignored equipment in most of the industries and they suffer consequential catastrophic failure due to this negligence. Diligent Protector will trip the blower even at the onset of faults such as starving for lubrication, impeller unbalance, excessive vibration, interference due to broken parts, etc.
