Description

<p>This industrial-grade product is designed to meet the rigorous demands of commercial electrical systems, offering robust performance and reliability. Suitable for various applications, it operates efficiently within a wide range of voltages and currents. The rated voltage spans from 20-60 VDC, accommodating diverse power requirements while maintaining a consistent rated current across its multiple configurations: 2 A, 6 A, 4 A, and 3 A. This flexibility ensures compatibility with numerous setups.</p><p>The unit supports both AC and DC circuits with a rated frequency of 50/60 Hz and a circuit voltage range of 24-60 VAC or 20-60 VDC. Its impressive rated impulse withstand voltage of 6 kV underscores its resilience against transient overvoltage conditions. Additionally, the product boasts a rated insulation voltage of up to 690 V, providing assurance in high-voltage environments.</p><p>Designed with practicality in mind, this device features a contact configuration of four normally open (4NO) contacts. The terminal type utilizes M4 screws with an optimal tightening torque set at 11 in-lb for both auxiliary and control circuits. This ensures secure connections that withstand operational stresses.</p><p>Engineered for safety and durability, the product carries an IP20 degree of protection rating—adequate for preventing ingress from fingers or similar objects—and mounts easily onto a standard 35 x 15 mm rail system. Installation is straightforward thanks to its compact dimensions: length at just 77 mm, width at 45 mm, and height at only 86 mm.</p><p>Its operational temperature range is extensive (-40 to +70&amp;#176;C), allowing it to function reliably under extreme conditions typical in Australian climates. Furthermore, it can endure ambient temperatures as low as -60&amp;#176;C up to +80&amp;#176;C without compromising performance.</p><p>For those concerned about compliance and standards adherence, this unit meets several key certifications including IEC/EN standards (60947-1 &amp;amp; -5-1), UL508 approvals as well as CSA C22.2 No.14-13 certification—ensuring peace-of-mind regarding international quality benchmarks.</p><p>Weighing just .27 kg makes handling easy during installation or maintenance tasks while still supporting an air thermal current capacity up-to16A along-with remarkable short-duration withstand currents peaking between100A–140A depending upon specific use-case scenarios ensuring robustness even amidst surge events!</p><p>Operating times vary slightly but remain efficient ranging anywhere from13ms through98ms; fast enough not only meeting industry norms but also enhancing overall system responsiveness!</p><p>Overall these technical specifications make this component ideal choice when seeking reliable solutions tailored towards demanding industrial/commercial settings requiring precision-driven results backed by solid engineering principles!</p>
