1SFL527102R1100

ABB 1SFL527102R1100 – AF205-40-00-11 is a heavy-duty 4-pole AF series power contactor designed for industrial motor starting, isolation, bypass, switching and electrical power-distribution applications. It features four normally open main contacts (4NO) and is rated at 205 A for AC-3 motor-duty operation. At 380–400 V, the contactor is suitable for motors up to approximately 110 kW, while at 440 V its AC-3 operational power rating reaches approximately 132 kW. The contactor incorporates ABB's AF electronic coil technology and operates across a wide control-voltage range of 24–60 V AC at 50/60 Hz and 20–60 V DC. This wide-range electronic coil is particularly useful in industrial control panels where control-supply voltage can fluctuate and helps reduce the requirement for multiple coil variants.
