ABB completes its range of advanced safety components that improve protection, maximize uptime, and accelerate project delivery.

ABB's all-new range of AFS contactors for safety applications is now available to order. The launch of the new contactors completes the expansion of the company's portfolio of safety components, making it possible to equip every aspect of a plant's safety architecture with ABB technologies!

A Boost of Safety!

The new AFS contactors can be part of the safety chain in industrial machinery and process industry applications, stopping motors or triggering gas discharges. For machine safety applications, AFS contactors come with fixed front auxiliary contact blocks that make monitoring and controlling circuits easier. The mechanically linked and mirror contacts also help make systems safer.

The all-new AFS contactors are designed to make integration into machine manufacturer systems easier. All the data for the contactors are readily available via safety design tools such as Sistema, or FSDT from ABB. For manufacturers, this makes it simpler to design machines with higher safety levels, complying with the main EN ISO 13849 and EN 62061 safety standards. 

A User-Centered Approach

ABB's ergonomic design eliminates confusion and increases safety! A protective cover helps prevent accidental manual operation. And as a standard, built-in surge protection is included. The device has a near-instantaneous response time. When a fault is detected, opening times are less than 30ms for selected variants. This enables designs with a significantly shorter safety distance.

Mechanically linked and mirror contacts are marked with symbols on the front and provide the performance required in feedback circuits. This prevents any unexpected state changes of the auxiliary contact, should the main contacts become welded or stuck. It also ensures an accurate indication of the safety system status is always displayed.

ABB contactors are efficient and easy to use! The range makes high-performance protection systems simpler to build. The power consumption of the contactor coil can be cut by up to 60 percent, enabling more compact transformers and panels. During routine maintenance, the distinctive yellow auxiliary contact block makes it faster to identify the safety device in the panel, saving valuable time.

Technical highlights:

• Up to 45kW - 400 V AC-3, 60hp - 480 V and 130A - 690 V AC-1, 115A - general use
• Fast opening times less than 30ms for selected variants
• Mirror and mechanically linked contacts with third party certificate
• Low energy auxiliary contacts feature a minimum switching capacity of 12 V, 3 mA 10-7
• Built-in surge suppression
• More information can be found in the AFS Contactors Safety Manual

ABB safety products bring quality and innovation to essential industrial equipment. ABB has also introduced a new range of Sentry Safety Relays that are simpler to install, make troubleshooting faster, and minimize downtime.
