Engineering data and characteristics
Approximate Values for three-phase Motors
Motor Full Load Currents
Approximate values of motor F.L.C. and minimum „slow blow“ respectively „gL“ short-circuit fuse
The motor F.L.C. be valid for standard internal and surface cooled three-pole motors with 1500 min-1. The fuses values be valid for the motor F.L.C. shown in the table
and D.O.L.-start: starting current max. 6x motor F.L.C., starting time max. 5s; star-delta-start: starting current max. 2x motor F.L.C., starting time max. 15s. For motors
with higher F.L.C., higher starting current and / or longer starting time, larger short-circuit fuses are required.
The maximum admissible value is dependent on the switchgear respectively thermal overload relay.

Contact Life
For selection of the suitable contactor-type according to supply volt-
age, power rating and application (utilization category AC1, AC3 or
AC4) use contact life characteristic diagram.
For the most common supply voltages four scales of power ratings Pn
are provided for each utilization category.
Select contactor-type according to utilization category AC3 (breaking
current Ia = Ie) using the motor rating scales to the right, according
to utilization category AC4 (breaking current Ia = 6 x Ie) using the
motor rating scales to the left.*1
Select contactor-type according to utilization category AC1 (breaking
current Ia = Ie/AC1) using the breaking current scale.*1
For contactors frequently used under AC3/AC4-mixed service condi-
tions calculate contact life with the formula:
1. Pay attention to the approved rated values of the selected
contactor according to the national approvals

M = Contact life (switching cycles) for AC3/AC4-mixed operations
AC3 = Contact life (switching cycles) for AC3 operations (normal switching

AC4 = Contact life (switching cycles) for AC4 operations (inching).
Breaking current Ia= multiples of rated motor current In.
