ABB AF16Z-30-22-20 1SBL176001R2022 2-stack 3-pole Contactors AC/DC

Rated working current: The "30" in the model number means that the rated working current of the main contact is 30A. This means that under the specified working conditions, the main contact can continuously and stably carry a current of 30A, ensuring the normal operation of the circuit without damage due to overheating and other problems.

Rated insulation voltage: The general rated insulation voltage is 690V, which indicates the maximum safe voltage that the main circuit part of the contactor can withstand. Within this voltage range, the insulation performance of the contactor can effectively prevent faults such as leakage and short circuit.

Rated working voltage: Common rated working voltage specifications are 230V, 400V, 690V, etc. When used specifically, it is necessary to select a contactor with a suitable rated working voltage according to the actual circuit voltage.

Conventional heating current: The conventional heating current is usually 30A, that is, under specific test conditions, the maximum current allowed to pass when the temperature rise of each part of the contactor does not exceed the specified limit value under 8-hour working system.
