ABB AFS Safety Contactors: Keep Your Machinery Safe with ABB Partner LED Controls
ABB AFS Safety Contactors combine proven AF contactor technology with dedicated safety features for applications where personnel protection, machine safeguarding and regulatory compliance are essential. LED Controls is a proud ABB Partner providing efficient access to ABB's complete range.
What Are ABB AFS Safety Contactors?
ABB AFS Contactors are 3-pole contactors specifically designed for machine safety applications. Unlike standard contactors, they incorporate permanently fixed safety auxiliary contacts, mechanically linked and mirror contact technology, and clear visual identification features to support safe machine operation. Essentially, Safety Contactors ensure that machinery is turned off and isolated to keep from re-activating until safe to do so.
Why Choose ABB AFS Contactors From LED Controls?
Built Specifically for Safety Applications
ABB AFS Safety Contactors are designed to support machinery complying with key international safety standards, including:
These standards are widely used when designing machine safety systems and determining Performance Level (PL) and Safety Integrity Level (SIL) requirements.
Guaranteed Contactor Status
Mechanically linked and mirror contacts ensure that - if a main contact becomes welded or stuck - auxiliary contacts cannot falsely indicate a safe condition. This is particularly important in safety feedback circuits where reliable status monitoring is critical.
Prevent Unexpected Operation
The yellow auxiliary contact block is permanently fixed to the contactor and cannot be removed during operation. On models up to 96 A, ABB also includes a transparent protective cover that prevents accidental manual operation or tampering.
Easy Safety Identification
The distinctive yellow auxiliary contact housing makes ABB AFS Safety Contactors immediately recognisable inside control panels, simplifying your fault finding and safety inspections.
ABB AF Technology Delivers Additional Benefits
A Variety of Applications
The range covers motor switching applications from 9 A up to 750 A, making it suitable for everything from small machinery to large industrial motor control systems.
Wide Voltage Range Coils
Many ABB AFS Safety Contactors are capable of operating across broad AC and DC voltage ranges. Depending on the model, only a small number of coil variants are required to cover voltages from 24 V to 500 V, keeping your product selection, stockholding and panel design straighforward.
Reduced Energy Consumption
AF technology coils can consume up to 60% less power than traditional contactor coils, allowing for:
- Smaller control transformers
- Reduced panel heat generation
- More efficient use of enclosure space
- Lower overall energy consumption
These advantages become increasingly important in larger motor control centres and complex machinery.
Built-In Surge Suppression
Conventional contactors often require separate suppression accessories, while ABB AFS contactors incorporate built-in surge suppression. This reduces installation complexity, protects sensitive control electronics and eliminates the need for additional suppression devices.
Fast Response for Enhanced Operator Protection
ABB AFS Contactors offer opening times as low as 20 milliseconds on selected PLC-controlled models. This rapid response helps minimise risk when a safety device detects a hazardous condition and initiates a machine stop sequence.
Typical Applications for ABB Safety Contactors
- Machine safety circuits
- Emergency stop systems
- Guard door monitoring systems
- Conveyor systems
- Packaging machinery
- Manufacturing automation
- Robotics cells
- Process equipment
- Industrial motor control centres
- Safety-rated power isolation systems
Wherever machinery must safely remove power during a hazardous event, ABB AFS Safety Contactors provide dependable switching and feedback performance.
