<p>When you&#39;re selecting a contactor for industrial or commercial applications, the AF Contactors offer reliable performance and robust specifications that meet a variety of technical requirements. Designed with precision, these contactors are suitable for operations demanding consistent power management.</p><p>The AF Contactors operate seamlessly at a rated voltage of 690 VAC and can handle rated currents of 42 A, 37 A, and 50 A. This versatility makes them well-suited to various electrical systems. Their operational frequency accommodates both 50 Hz and 60 Hz environments, providing flexibility in different settings.</p><p>Safety is paramount with the AF Contactors. They boast a rated impulse withstand voltage of up to 6 kV and an impressive insulation voltage rating of both 690 VAC and 600 V. These features ensure that the system remains protected against unexpected surges or electrical faults.</p><p>In terms of durability under stress conditions, these contactors perform admirably with a short-time withstand current capability: they can endure up to 700 A for one second. For extended durations like one minute or fifteen minutes, they manage currents up to 150 A and 50 A respectively. This resilience ensures reliability during peak load conditions.</p><p>The contact configuration is straightforward yet effective with three normally open (3NO) contacts. The terminal type is screw-based, facilitating secure connections while simplifying installation processes.</p><p>Protection from environmental factors is assured by an IP20 degree of protection alongside an IP3 degree of pollution rating. These ratings indicate that the product is designed to resist ingress from fingers or objects larger than 12 mm while maintaining functionality in moderately polluted atmospheres.</p><p>Installation is user-friendly thanks to its screw mounting type which aligns perfectly with standard setups in industrial panels. Additionally, wire stripping lengths are specified as follows: control circuits require a stripping length of 10 mm while main circuits need a length of 14 mm—ensuring optimal connectivity without excess exposure.</p><p>Dimension-wise, these contactors are compact: measuring at just 45 mm wide by both height and depth being equal at 86 mm each—allowing for easy integration into existing systems without requiring substantial space adjustments.</p><p>Compliance with international standards such as IEC/EN60947-1, IEC/EN60947-4-1 along with UL60947-4-1 and CSA C22.2 No.60947-4-1 underscores their global applicability ensuring they meet rigorous safety benchmarks across markets globally.</p><p>With an air thermal current capacity reaching up to50A these devices provide robust thermal management capabilities essential for maintaining optimal operating temperatures even under heavy loads ensuring longevity &amp; efficiency throughout their lifecycle.</p>
