PSE18
In-line connected
(400 V) kW 7.5
IEC, Max. A 18
(440-480 V) hp 10

UL, Max FLA
400 V, 40 ºC
Using MCCB only, type 1
MCCB (35 kA), type
coordination will be achieved
MCCB (50 kA), type
To achieve type 2 coordina-
Fuse protection (85 kA), Semiconductor fuses, Bussmann, type
tion, semi-conductor fuses
must be used 170M1563
Switch fuse, type
Suitable switch fuse for re-
commended semi-conductor
fuses
The line contactor is not Line contactor, type
required for the softstarter
itself but often used to open
if OL trips
Overload protection is used Electronic overload relay, type
to protect the motor from
over heating
The by-pass will reduce the By-pass, type
power loss of the softstarter.
A50 ... A300 might be replaced by AF50 ... AF300
