Duty Cycle: Why a Shredder Stops Halfway Through the Job

A shredder stopping mid-task is usually not a fault. It is the machine protecting its motor.

Run time and cool-down

Makers publish a continuous run time and a required rest period. Exceed the first and thermal protection trips, and the machine will not restart until it has cooled.

Plan around it

For a large clear-out, work in blocks with breaks rather than pushing until it stops. That is easier on the motor and finishes sooner in practice.

Continuous-duty machines

Some models are built for long runs. If you regularly shred in volume, that specification is worth more than a higher security rating you do not need.

Overfeeding

Pushing more sheets than the rated capacity is the other common cause of stopping. Feed within the rating and jams become rare.
