ABB AF16Z-30-22-22 1SBL176001R2222 2-stack 3-pole Contactors AC/DC

Electrical life: Under the AC-3 use category (starting and breaking of cage induction motors), the electrical life can generally reach more than 1 million times; under the AC-1 use category, the electrical life is higher, up to millions of times. This reflects the ability of the contactor to work reliably under load.

Mechanical life: Usually the mechanical life can reach more than 10 million times, which reflects the durability and reliability of the contactor's mechanical structure, that is, the number of times the contactor can normally open and close the switch without considering the load.

Operating frequency: Generally up to 1200 times/hour, that is, the maximum number of opening and closing operations that the contactor can perform per hour, which is very important for application scenarios that require frequent operation.
