<p>The AF Contactors are a reliable choice for industrial and commercial applications, designed to meet the demanding requirements of modern electrical systems. With a robust rated voltage of 690 VAC and a range of rated currents at 32 A, 40 A, and 45 A, these contactors offer flexibility across various operational needs. They operate efficiently at both 50 Hz and 60 Hz frequencies, making them suitable for diverse environments.</p><p>One of the standout features is their rated impulse withstand voltage of 6 kV, ensuring resilience against transient overvoltages. The contactors also boast a comprehensive rated insulation voltage capability up to 690 VAC and an additional rating at 600 V, providing enhanced safety margins in complex installations.</p><p>The short-time withstand current ratings further highlight their durability under stress: capable of withstanding up to 700 A for one second and maintaining performance under reduced loads over extended periods—350 A for ten seconds or down to 50 A over fifteen minutes. This makes them particularly suited for applications where temporary surges are expected.</p><p>With a straightforward screw terminal type design and IP20 degree protection, these contactors offer ease during installation while maintaining protection against accidental touch by fingers or similar objects greater than 12 mm in diameter. The additional degree of pollution rating at IP3 ensures they can handle moderately polluted environments without compromising performance.</p><p>For mounting purposes, the screw-type configuration offers stability and security once installed. Wire stripping lengths are specified as well—10 mm for control circuits and 14 mm for main circuits—allowing precise preparation during setup.</p><p>In terms of physical dimensions, these units measure compactly with a width of just 45 mm combined with an equal height and depth each measuring at 86 mm; this compact form factor allows easy integration into existing panels without requiring extensive space adjustments.</p><p>Compliance with international standards such as IEC/EN 60947-1, IEC/EN 60947-4-1 along with UL certification (UL60947-4-1) plus CSA C22.2 No.60947-4 ensures that these contactors meet rigorous quality benchmarks recognized globally.</p><p>Lastly but importantly is their air thermal current capacity set firmly at fifty amps which underscores reliability even when operating continuously within specified parameters thus reinforcing confidence among users looking towards longevity alongside exceptional performance from products they depend upon daily operations whether onsite factories warehouses offices other commercial venues alike thanks largely due attention detail throughout entire design process culminating what truly represents solid investment any discerning professional seeking optimal solutions today tomorrow beyond!</p>
