<p>When it comes to ensuring the reliability and safety of your electrical systems, this voltage monitoring relay offers a robust solution. Designed for industrial and commercial applications, it operates within a measuring range of 90-170 VAC (L-N) and is rated for the same voltage. With its ability to handle a rated current of 4 A and function at both 50/60 Hz frequencies, this device is versatile enough to meet various operational needs.</p><p>The relay features a 2CO SPDT contact form, allowing for flexible switching capabilities. Its contact configuration is also 2CO SPDT, ensuring consistency in performance. The unit mounts easily on a standard 35 x 7.5 mm DIN rail, providing straightforward installation in control panels or other setups.</p><p>For those concerned about durability, this relay boasts an impressive electrical durability of up to 100000 operations and mechanical durability reaching up to 30000000 operations. Such longevity makes it an excellent investment for long-term projects where maintenance downtime must be minimized.</p><p>Safety standards are well covered with approvals including CAN/CSA C22.2 No.14, IEC/EN standards such as IEC/EN 63000, IEC/EN 60255-27, IEC/EN 61000-6-2, IEC/EN 61000-6-3 as well as UL508 certification—providing peace of mind that this product meets rigorous international safety requirements.</p><p>Functionality extends beyond basic monitoring; it provides over and undervoltage monitoring along with phase failure detection—a crucial feature for maintaining system integrity during power anomalies. Additionally, phase unbalance detection and phase sequence monitoring ensure that all phases are operating correctly while interrupted neutral monitoring adds another layer of protection against potential faults.</p><p>The operational temperature range from -25&#176;C to +60&#176;C ensures reliable performance across diverse environmental conditions whether it&#39;s installed in hot factory floors or cooler warehouse environments. With an IP20/IP50 degree of protection combined with IP3 pollution degree rating users can trust its resilience against dust ingress though care should be taken regarding water exposure due to these ratings being more focused on solid object protection.</p><p>Weighing only 0.148 kg this compact device measures just 22.5 mm wide by 85.6 mm high making space management within enclosures simple without compromising functionality or ease-of-access via screw-type terminals which facilitate secure connections during setup or maintenance periods</p><p>In summary if you&#39;re seeking dependable voltage surveillance coupled with comprehensive protective functions then consider integrating this relay into your system architecture today</p>
