Using MCCB only, type 1
coordination will be achieved.
MCCB (50kA), type
T2S160 T3S250
To achieve a type 2 coordina-
tion, semi-conductor fuses
must be used.
Fuse protection (65kA), Semiconductor fuses, Bussmann, type
170M1566 170M1568 170M1569 170M1570 170M1571 170M1572 170M3819 170M5809
Suitable switch fuse for re-
commended semi-conductor
fuses.

OS32GD03P
OS63GD03P OS125GD03P OS250D03P OS400D03P
The line contactor is not
required for the softstarter
itself but often used to
open if OL trips
Line contactor, type
AF30 AF38 A50 A63 A75 A95 A110 A145
Overload protection is used
to protect the motor from
over heating
Electronic overload relay
Built-in
The by-pass contactor will
reduce the power loss of the
softstarter. All softstarters
can be operated without
by-pass
By-pass contactor, type
AF16 AF26 AF30 A40 A50 A63 A95
A50 ... A300 might be replaced by AF50 ... AF300.
