<p>When selecting a reliable and efficient phase monitoring relay for industrial or commercial applications, this product offers a robust solution tailored to meet your technical needs. Designed to operate within a measuring range of 300-500 VAC (line-to-line), it ensures compatibility with systems requiring a rated voltage of 300-500 VAC and a rated current of up to 4 A. This versatility is complemented by its ability to function seamlessly at both 50 Hz and 60 Hz frequencies.</p><p>The relay is equipped with a contact form and configuration of 2CO SPDT, offering dual changeover contacts that enhance operational flexibility. It mounts easily on either a 35 x 15 mm or 35 x 7.5 mm DIN Rail using screw terminals, making installation straightforward even in complex setups.</p><p>Measuring just 22.5 mm in width and standing at a height of 85.6 mm, the compact design optimizes space utilization without compromising performance. The device features an operating time that includes a start-up delay of approximately 200 ms and an adjustable tripping delay ranging from as short as 0.1 seconds to as long as 30 seconds, allowing precise control over response times based on specific application requirements.</p><p>Functionality-wise, this relay excels in detecting phase failures, monitoring phase sequences, and identifying phase unbalances—critical capabilities for maintaining system stability and preventing equipment damage due to electrical faults.</p><p>Durability is another strong suit; the electrical durability extends up to an impressive count of 100000 operations while the mechanical durability reaches up to an astonishing count of thirty million operations, ensuring longevity even under rigorous conditions.</p><p>The product boasts protection degrees IP20/IP50 against solid objects like fingers or dust particles while maintaining operational integrity in environments classified under degree of pollution IP3. It operates efficiently across temperatures ranging from -25&#176;C to +60&#176;C—suitable for various climatic conditions typical in Australia.</p><p>Adherence to international standards such as CAN/CSA C22.2 No.14, IEC/EN regulations including but not limited to IEC/EN 63000, IEC/EN60255-27, IEC/EN61000-6-2/-6-3 alongside UL508 approval underscores its commitment towards safety compliance and quality assurance.</p><p>Weighing only about .132 kg makes handling easy during installation or maintenance activities without adding unnecessary load onto existing structures or panels—a feature appreciated by technicians focused on ergonomic considerations during setup processes.</p>
