ABB AFS Contactors For Safety Applications

Help Make Your System Safer

Some regular contactors meet the minimum requirements to make them suitable for safety circuits, these include the standard AF contactors from ABB. However the contactor itself will not meet PLe and requires additional removable contacts to be configured in a certain way for redundancy. If setup in the wrong way, or if altered at a later time by a different person, the safety integrity may not be valid. Therefore using a dedicated Safety contactor such as the AFS series give you the peace of mind ensuring every time the contactors meet the requirements you need, and cannot be altered.

Designed for machine safety applications, AFS Contactors come with factory mounted non-removable contact blocks (mechanically linked and mirror contacts) making them ideal for monitoring and controlling circuits. ABB’s complete range of safety components make protection systems easier to build.
