<p>When selecting the right contactor for your industrial or commercial applications, understanding the technical specifications and performance capabilities is crucial. The AF Contactors offer a reliable solution, engineered to meet demanding operational requirements with precision.</p><p>These contactors are designed for use in circuits with a rated voltage of up to 690 VAC, making them suitable for high-voltage applications. With a rated current capacity of 40 A and 32 A, they provide flexibility depending on your specific electrical needs. Operating at both 50 Hz and 60 Hz frequencies ensures compatibility across various systems.</p><p>A key feature is their robust withstand capability; these contactors have a rated impulse withstand voltage of 6 kV, ensuring resilience against transient overvoltages. Furthermore, they boast impressive short-time withstand currents: handling up to 700 A for one second and maintaining stability under prolonged stress with ratings like 350 A for ten seconds.</p><p>The contact configuration is set at three normally open (3NO), which is standard for many load control applications. Installation is straightforward due to the screw terminal type and screw mounting method, providing ease of integration into existing setups.</p><p>In terms of dimensions, these compact units measure just 45 mm in width, standing at a height of 86 mm and extending to a depth of 119.5 mm—ideal for space-constrained environments while not compromising on power delivery.</p><p>Safety and compliance are paramount; these contactors adhere strictly to international standards such as IEC/EN 60947-1, IEC/EN 60947-4-1 along with UL and CSA certifications (UL 60947-4-1, CSA C22.2 No. 60947-4-1). This guarantees that they meet rigorous safety benchmarks essential in today&#39;s regulatory landscape.</p><p>The degree of protection offered by an IP20 rating ensures basic protection against solid objects larger than finger size but does not guard against water ingress—something worth noting depending on your installation environment&#39;s exposure levels.</p><p>For pollution conditions classified as IP3 according to industry norms, these devices can operate effectively without degradation from dust or other contaminants typically found in industrial settings.</p><p>Wire stripping lengths are specified clearly: auxiliary circuits require a length of ten millimeters as do control circuits while main circuits need fourteen millimeters ensuring optimal connection integrity during installation or maintenance processes.</p><p>Lastly, air thermal current ratings stand at either fifty amps or sixteen amps based on application demands further emphasizing their versatility across different operational scenarios within industrial ecosystems where reliability cannot be compromised.</p>
