<p>When considering robust solutions for industrial and commercial electrical applications, AF contactors stand out as reliable components designed to meet demanding operational requirements. This specific AF contactor is engineered with a rated voltage of 690 VAC and can handle rated currents of 24 A and 28 A, making it suitable for various applications that require efficient control of electrical circuits.</p><p>Operating at both 50 Hz and 60 Hz frequencies, this contactor offers versatility in different power systems. It boasts a rated impulse withstand voltage of 6 kV, ensuring resilience against transient over-voltages. The insulation capabilities are notable too, with a rated insulation voltage of up to 690 VAC and an additional rating at 600 V.</p><p>For scenarios involving short-term high current demands, this contactor is well-equipped: it can withstand currents up to 700 A for one second, or sustain lower levels such as 350 A for ten seconds. Its ability to endure these conditions without compromising performance makes it particularly useful in environments where reliability under stress is critical.</p><p>The contact configuration features three normally open (3NO) contacts, providing straightforward integration into existing systems. Installation is facilitated by screw-type terminals and mounting options, ensuring secure connections while maintaining ease of use during setup or maintenance tasks.</p><p>Safety standards are rigorously met with an IP20 degree of protection against solid objects larger than 12 mm. Additionally, the unit carries an IP3 degree of pollution rating which indicates its suitability for environments where conductive pollution could be present but not excessive.</p><p>Regarding dimensions, the compact form factor—45 mm wide by 86 mm high by 77 mm deep—enables installation even in space-constrained settings without sacrificing functionality or accessibility. The wire stripping length required is a manageable 10 mm.</p><p>Compliance with international standards such as IEC/EN 60947-1 and IEC/EN 60947-4-1 ensures that this product adheres to global safety and performance benchmarks. It also meets UL and CSA certifications (UL 60947-4-1; CSA C22.2 No.60947-4-1), expanding its applicability across regions requiring these specific approvals.</p><p>Finally, the air thermal current ratings offer additional insights into its operational limits: capable of handling continuous currents up to either 35 A or alternatively at lower thresholds like16 A depending on application needs.</p>
