ABB AF52-30-11-12

The AF52 contactors are specifically engineered for managing power circuits with a voltage range of up to 690 V AC and 220 V DC. These contactors are primarily used for controlling three-phase motors, as well as non-inductive or slightly inductive loads. The AF52 series includes an electronic coil interface that accepts a wide control voltage range, from 24 V to 500 V at 50/60 Hz or from 20 V to 500 V DC.

These contactors are designed to handle large variations in control voltage. They offer four coils that cover a wide range of control voltages, making them adaptable for use worldwide without any need for coil changes. The AF52 series also features built-in surge protection, eliminating the requirement for additional surge suppressors.

The 3-pole contactors in this series are of the block type design. They come with three main poles and a side-mounted auxiliary contact block that includes one normally open (N.O.) and one normally closed (N.C.) contact, as well as front-mounted add-on auxiliary contact blocks. These auxiliary contacts comply with Annex L of IEC 60947-5-1 and feature the
