UL, Max FLA
400 V, 40 ºC
MCCB (50kA), type
Using MCCB type 1
coordination will be
achieved
Fuse protection (65kA), Semiconductor fuses, Bussmann, type
To achieve type 2 coordina-
tion semi-conductor fuses
must be used
Switch fuse, type
Suitable switch fuse for
the recommended semi-
OS125GD03P
conductor fuses
Overload protection is used Thermal overload relay, type
to protect the motor from
over heating
Line contactor, type
The line contactor is not
required for the softstarter
itself but often used to
open if OL trips
By-pass contactor, type
The by-pass contactor will
reduce the power loss of
the softstarter. All softstar-
ters can be operated
without by-pass
Current transformers, type
Must be used if current limit
function is required
