<p>If you&#39;re in the market for a robust solution to ensure reliable power monitoring, this phase failure detection and neutral monitoring device might be what you need. Engineered to cater to the demands of industrial and commercial applications, it offers precise functionality within a compact form factor.</p><p>This device operates efficiently within a measuring range of 380-440 VAC (L-L) or 220-240 VAC (L-N), making it versatile for various electrical systems. With a rated voltage matching its measuring range, it is designed to handle an operational current up to 4 A effortlessly while maintaining a consistent frequency of 50/60 Hz.</p><p>The contact configuration is straightforward with a single normally open (1NO) contact form. This simplicity ensures ease of integration into existing systems without unnecessary complexity. Designed for DIN rail mounting, it fits both 35 x 15 mm and 35 x 7.5 mm rails, offering flexibility depending on your setup needs.</p><p>Installation is made user-friendly with screw terminal types that provide secure connections without hassle. The unit&#39;s dimensions are compact at just 22.5 mm in width and 78 mm in height, allowing for efficient use of space within control panels or switchboards.</p><p>In terms of performance timing, the device features a start-up delay of 500 ms and a tripping delay set at 150 ms, ensuring quick response times when detecting anomalies in phase conditions or neutral status. This rapid reaction helps prevent potential damage from phase loss or imbalance scenarios.</p><p>Protection standards are well-covered with an IP20 rating ensuring basic protection against solid objects larger than 12mm like fingers or similar objects; additionally, an IP50 degree provides dust protection sufficient for indoor environments where dust levels are controlled but not entirely absent.</p><p>Operational temperature ranges from -20&#176;C to +60&#176;C enable usage across diverse environmental conditions typical in Australian climates—from cooler southern regions to warmer areas up north—without compromising reliability or performance consistency.</p><p>Certified under CAN/CSA IEC/EN UL standards and approvals, this product meets stringent quality assurance criteria recognized globally which adds confidence regarding safety compliance during operation across different jurisdictions including Australia’s rigorous electrical standards framework.</p><p>Weighing only about 0.066 kg ensures minimal impact when considering total load calculations on equipment racks or enclosures—a small yet significant detail that complements its overall efficiency-driven design philosophy aimed squarely at delivering dependable service over long-term deployments.</p>
