Contactors type AF1350 / AF1650

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

Description
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. auxiliary contacts (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 distinct closing 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
