scope:
The filter consists of a surge arrester, a capacitor in series with charge and discharge resistors upstream and downstream of the capacitor. The use of this filter is to limit voltage surges. Alternative methods are acceptable, subject to agreement between purchaser and supplier. The filter may be requested suitable for outdoor or indoor mounting. The applicable parameters of the protection should be chosen should be chosen by the designer of the protection and approved by the purchaser.
