Contactors type AF1350 / AF1650

AF1350/AF1650 3-pole Contactors
a.c./d.c. Operated - Wide voltage range Electronic Coil Interface

The AF1350/AF1650 3-pole contactors are of the block type design. ● Main poles and auxiliary contact blocks – 3 main poles, – 1 N.O. and 1 N.C. auxiliary contacts (1 contact block fitted on the left hand side). – 2 N.O. and 2 N.C. auxiliarycontacts (1 contact block fitted on each side) A maximum of 4 auxiliary contact blocks can be fitted on each contactor. ● Electronic control The contactors are fitted with an electronic coil interface controlled by a specific integrated circuit developed by ABB. Advantages – Wide voltage range, 100...250 V a.c. and d.c. – Can manage large voltage variations – Reduced power consumption – Very distinctclosing and opening – Noise free – Can withstand voltage interruptions or voltage dips in the control supply (≤ 20 ms) ● Control inputs The AF1350/AF1650 contactors are as standard equipped with low voltage inputs for control, for example by a PLC

AF1350/AF1650 3-pole Contactors
a.c./d.c. Operated - Wide voltage range Electronic Coil Interface

● The most compact 1650A contactor ● Modern family design to match other ABB products ● Type 2 coordinated with breakers ● Electronic coil interface ● PLC operation possible ● cULus approved ● Low environmental impact thanks to Life Cycle Assessment

AF1350 and 1650are modern and compact 3-pole contactors designed for heavy duty industrial applications. They are designed for carrying and switching both inductive (AC-3) and resitive (AC-1) loads. High mechanical and electrical endurance make them suitable also for motor applications. Typical applications are as: – Transfer switch or as main isolation contactor in generator sets – Main contactor for staticpower switching – Main or by-pass contactor in windmills – Main or by-pass contactor for frequency drives and softstarters – Y/D starters for example on board ships The coil is electronically controlled with features such as wide coil voltage range, low pull-in value and low power consumption to mention some of the features. It can also be operated with a low voltage signal directly from a PLC. Thesecontactors are fully tested together with ABB breakers to meet type 2 co-ordination. For motor applications there is a three phase electronic overload relay called E1250 DU available.
