ABB 1SFL487002R1111

The AF190-30-11-11 contactor is designed to manage motor operations and power circuits with a maximum switching capacity of 275 A for AC-1 applications and 250 A for UL general use. It can handle motor loads up to 90 kW at 400 V AC (AC-3) or 125 hp at 480 V UL. This unit features a wide control voltage range of 24-60 V at 50/60 Hz and 20-60 V DC, accommodating significant voltage fluctuations to enhance operational stability.

Integrated surge protection contributes to its compact design, while a block-type configuration allows for easy expansion with auxiliary contact blocks and various accessories. The product complies with IEC 60947-4-1 standards, ensuring reliable thermal performance with a conventional free-air thermal current rating of 275 A at 40 °C.

Furthermore, its mechanical durability is rated at 5 million cycles, and the maximum electrical switching frequency reaches 300 cycles per hour for AC-1 applications. With a degree of protection rated at IP20 for coil terminals, this contactor is well-suited for diverse industrial environments.
