12/84 ABB MOTOR PROTECTION AND CONTROL

—
Direct-on-line starters protected by manual motor starters

With AS, ASL contactors - open type version in kit form

Application
Full voltage direct-on-line starting for controlling three-phase asynchronous motors is a
simple and economic solution characterised by a high starting torque (1.9 to 2.1 times full-
I >
speed torque) and a starting current 5.5 to 7 times nominal current.

Coordination types
The contactor and the manual motor starter control and protect motors against overload
and short-circuits according to coordination types 1 and 2 (IEC 60947-4-1 / EN 60947-4-1)
defining the anticipated level of service continuity as follow:
Type 1: In short-circuit conditions, the contactor or starter does not endanger persons or in-
stallations and will not be able to then operate without being repaired or having
parts replaced.
Type 2: In short-circuit conditions, the contactor or starter does not endanger persons or in-
stallations and will be able to operate afterwards. The risk of contacts light welding
is acceptable.
