13/22 ABB MOTOR PROTECTION AND CONTROL

—

DOL starters protected by moulded-case circuit-breakers and overload relays
With AF contactors - open type version in kit form

Application
Full voltage direct-on-line (DOL) 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
XT2S 160 + BEA140/XT2 + The contactor and the moulded-case circuit-breaker control and protect motors against
AF140-30-11
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.
