ABB AF09-40-00-11 AF Contactor, 24 V ac/dc Coil, 4 Pole, 25 A, 4 kW, 4NO

Use this ABB contactor to safely switch your high-current industrial hardware. As indicated by its current rating of 25A, it can handle the large electrical loads needed for reliable equipment activation. For wide system coverage, the device switches up to four circuits at once with its four poles. Built-in surge protection means it resists damage from electrical faults, so you can be sure of reliable control. As this contactor has a response time of between 11 and 95ms, it quickly reacts to your inputs and achieves efficient switching.

• Up to 600 electrical switching cycles per hour for reliable repeated switching
• Low power loss of 0.8W per active pole for energy-efficient activation
• Mounts onto a universal DIN rail for simple installation in existing control cabinets
• Works with AC and DC supplies at 24V for wide compatibility

• Motor starters
• Lighting systems
• Power distribution
• Aerospace industry

A contactor such as this unit performs the same repetitive switching processes as a relay, but handles larger current loads, usually over 10A.
