Cylindrical aluminum case
Also available in high-grade, freon-resistant
steel case upon request
Coaxial winding design with internal
low-inductance circuitry
Mounting bolt M12

q
Screw terminals M6 … M12
Mounting parts
q
If the vibration stress is
≤
5
g
and the capacitors are
≤
60 mm
in diameter and
≤
160 mm in height, the bolt is used for mounting.
refer to chapter “Mounting parts”.
q
In case of a vibration stress > 5
g
as well as for larger-sized capacitors
Grounding
q
Mounting bolt for grounding in accordance with VDE 0100
q
Grounding identification in accordance with DIN 40 011
Overpressure disconnector (mechanical)
When the overpressure disconnector responds,
the capacitor extends by up to 12 mm.
So leave sufficient space above the terminals when mounting the capacitor.
Individual data sheets
Individual capacitors of this series are specified in detail
(incl. thermal data)
on pages 222 … 261.
Upon request, these data sheets are available for each capacitor type.
