Frequently Asked Questions
Is 1.9 x 15 mm actually P-5?
Yes. DIN 66399 caps P-5 particles at 30 mm²; 1.9 x 15 mm is 28.5 mm². Note that the imperial figure Kobra prints on the US datasheet, 3/32 x 5/8 in., converts to about 38 mm² and would not qualify — it is a rounded conversion, not the measured particle. The metric dimensions on Kobra's European datasheet are what the rating is based on.
How can it take 31 sheets when the 310 TS CC2 takes only 19 with the same cut?
Motor and drive. The 400 chassis uses a 2.9 HP unit through a heavier chain drive and runs at 30 ft/min; the 310 TS uses 1.5 HP at 17 ft/min. Same particle geometry, roughly twice the power to produce it. That is the whole reason to pay for the larger cabinet if you need P-5 for a busy department.
Can it really shred USB flash drives?
Kobra's US product listing for the 400 C2 includes USB pen drives among the shreddable materials, alongside cards and optical discs. Two practical cautions: shredding hard plastic and metal shortens knife life compared with paper-only use, and the resulting fragments are not evaluated against any electronic-media destruction standard. For routine destruction of flash media at a defined security class, use a purpose-built electronic media shredder rather than a paper machine.
Is this shredder NSA approved?
No. NSA/CSS Specification 02-01 requires a maximum 1 x 5 mm particle and a current entry on the NSA/CSS Evaluated Products List. The 400 C2 meets neither condition. A P-5 rating is a DIN 66399 classification and carries no NSA standing. The EPL-listed machine in this cabinet is the KOBRA 400 HS-6.
What does it cost to keep running?
Two consumables: waste bags (art. SB-35, 50 per box) and shredder oil for the automatic oiler (art. SO-1032, 7 oz). Bag consumption depends on volume; oil consumption is modest but continuous, and running the oiler dry is the fastest way to lose the particle consistency the P-5 rating depends on. Budget for both from day one rather than discovering them later.
Will it fit through a standard doorway and survive an office floor?
The cabinet is 23.5 in. wide and 36.5 in. tall, so it passes a standard 32-inch door on its casters. Weight is the real consideration: 222 lb concentrated on four castors will mark soft flooring and is a two-person move at minimum. Plan the siting before delivery rather than after.
How loud is it?
58–61 dB(A) while cutting, which is conversation level at close range. It is fine in a print room, a copy alcove or a mail room. In a quiet open-plan area it will be heard clearly, and at 30 ft/min it runs for less time per document than a slower machine, which helps more than the decibel figure suggests.
