<p>The AF Contactors are a robust choice for industrial and commercial applications, providing reliable performance with a focus on essential technical specifications. Designed to handle demanding environments, these contactors come with a rated voltage of 690 VAC and support various current ratings of 42 A, 37 A, and 50 A. This flexibility ensures compatibility across different systems.</p><p>Operating at both 50 Hz and 60 Hz frequencies, the AF Contactors deliver consistent performance in diverse settings. The rated impulse withstand voltage is an impressive 6 kV, offering protection against transient overvoltages typically found in industrial applications. With a rated insulation voltage of up to 690 VAC and additional support for systems requiring up to 600 V, these contactors meet rigorous safety standards.</p><p>Short time withstand currents further demonstrate the product&#39;s resilience: capable of handling up to 700 A for one second or maintaining stability at lower currents such as 350 A for ten seconds. These features ensure that the contactor can manage overloads without compromising its integrity.</p><p>The contact configuration is set at three normally open (3NO), which suits standard industrial requirements. Installation is straightforward thanks to screw-type terminals and mounting options that align with common industry practices. The wire stripping length is specified as 10 mm for control circuits and extends to 14 mm for main circuits, facilitating easy setup during installation processes.</p><p>With dimensions measuring a compact width of only 45 mm along with height and depth both at 86 mm, the AF Contactors fit seamlessly into existing setups without occupying excessive space. They maintain an IP20 degree of protection against solid objects larger than fingers while adhering to pollution degree IP3 standards—a testament to their durability in less-than-ideal conditions.</p><p>Adherence to international standards like IEC/EN 60947-1, IEC/EN 60947-4-1 alongside UL and CSA certifications underscores the product’s compliance with global safety norms—ensuring peace of mind regarding reliability across borders.</p><p>For air thermal current needs reaching up to an air thermal current rating of about fifty amps (50A), this unit stands out as particularly effective under normal operating conditions while remaining robust enough when faced with unexpected surges or fluctuations within electrical systems typical within heavy-duty operations seen around Australia today!</p>
