13/38 ABB MOTOR PROTECTION AND CONTROL

—

DOL and reversing starters protected by overload relays
With AF contactors - Open type version in kit form

Application
Full voltage direct-on-line and reversing 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-speed torque) and a starting current 5.5 to 7 times nominal current.

Coordination Types
The contactor, the short-circuit protection device and the thermal overload relay 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-
1SFC101153V0001 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-
AF140-30-11 + TF140DU stallations and will be able to operate afterwards. The risk of contacts light welding
is acceptable.
