Rexel Momentum Extra jam free paper shredders are ideal for destroying confidential documents in the office. The XP520+ shredder machine shreds up to 20 sheets of A4 paper (80gsm) in one go through the manual feed slot into P-5 (2x15mm) cross-cut pieces. Active sensing technology measures the number of sheets being fed in real-time to stop paper jams and misfeeds; indicated by a red LED on the control panel. This paper shredder will not operate until the number of sheets is reduced below or at the maximum sheet capacity. This cross-cut shredder is designed for moderate to heavy use with its high sheet capacity, large 120L bin size and continuous run time. There's no need to manually feed paper, or remove staples and paper clips first; this Rexel shredder also safely shreds CDs, DVDs and credit cards through a separate feed slot.
