Using MCCB type 1
coordination will be
achieved
MCCB (50kA), type
T2S160 T3S250 T4S320 T5S400
To achieve type 2 coordina-
tion semi-conductor fuses
must be used
Fuse protection (65kA), Semiconductor fuses, Bussmann, type

Suitable switch fuse for
the recommended semi-
conductor fuses
Switch fuse, type
OS125GD03P OS250D03P OS400D03P OS630D03P
Overload protection is used
to protect the motor from
over heating
Thermal overload relay, type
TA110DU TA200DU TA450DU
The line contactor is not
required for the softstarter
itself but often used to
open if OL trips
Line contactor, type
A95 A110 A145 A185 A260 A300
The by-pass contactor will
reduce the power loss of
the softstarter. All softstar-
ters can be operated
without by-pass
By-pass contactor, type
A50 A63 A95 A145 A210
Must be used if current limit
function is required
