Mains filter
A mains filter is a mains choke and RFI filter combination in
a housing. Mains filters offer the same advantages as a mains
choke and are also used to comply with interference voltage
categories according to European standard EN 61800-3. A
distinction is made in this legislation between category C1
and category C2.
Category C1
is used in public networks (residential areas). In
terms of limit values category C1 corresponds to class B as
laid down in EN 55011.
Category C2
is used in industrial premises, but also in resid-
ential areas if deemed appropriate by the user. In terms of
Mains filters A and B
limit values category C2 corresponds to class A as laid down
in EN 55011.
Mains filter A, mains filter B and other mains filters are
available for 9300vector inverters for compliance with inter-
ference voltage categories.
As well as reducing the cable-linked interference voltage, a
mains filter achieves the efficiency of a mains choke which
The choice of components depends on the motor cable length
and interference voltage category required.
also reduces the r.m.s. value of the mains current.Mains

Mains filters are available in a power range of 0.37 … 90kW.
Mains filter A, C2 up to 5m
Mains filter A is used to operate 9300 inverters in industrial
areas, e.g. on industrial networks. With mains filter A, EN
