The 4-pole AF09 contactors represent a compact series with AC/DC control and very wide coil voltage ranges. They switch power circuits with slightly inductive or non-inductive loads. Only 4 coils cover control voltages from 20 to 500 VDC and from 24 to 500 VAC. They feature integrated overvoltage protection and do not require additional suppression components. All integrated or retrofittable normally open auxiliary contacts are designed as mirror contacts according to IEC60947-5-1 Annex L. Additional accessories such as time delay relays, wiring aids, and interlocking components complete the range.
