<p>When it comes to ensuring the reliability and safety of electrical systems, having robust monitoring devices is crucial. This phase failure detection and phase sequence monitoring unit offers a practical solution for maintaining system integrity in industrial and commercial settings.</p><p>Designed to operate within a measuring range of 200-500 VAC (L-L), this device is well-suited for monitoring standard voltage levels found in many applications. The rated voltage also falls within the same 200-500 VAC range, ensuring compatibility with various systems without requiring additional adjustments.</p><p>The contact form and configuration are both specified as 2CO SPDT (Single Pole Double Throw). This means the device can effectively switch between two circuits, offering flexibility in control applications. The terminal type uses screw connections, providing secure and easy installation or replacement when needed.</p><p>Physically, the unit has been designed with compactness in mind. With a width of just 22.5 mm and a height of 85.6 mm, it fits comfortably into most standard installations without consuming excessive space. Despite its small size, it remains rugged enough to handle demanding environments thanks to its operational temperature range from -20 to 60 degrees Celsius.</p><p>One notable feature is the operating time which includes a start-up delay of 500 ms. This delay ensures that transient conditions do not cause unnecessary tripping or alarms during initial power-up sequences—an important consideration for maintaining stable operations.</p><p>In terms of compliance and safety standards, this product meets several international certifications including CAN/CSA IEC/EN UL approvals. These endorsements underscore its quality and reliability across different regions, making it an attractive choice for global operations seeking standardized solutions.</p><p>Weighing only 0.127 kg, this lightweight device does not add significant load to existing setups while still delivering robust performance over time.</p><p>Overall, if you&#39;re looking for dependable phase failure detection coupled with phase sequence monitoring capabilities suitable for your electrical system requirements within the specified voltage range—this product stands out as a solid choice backed by recognized standards and practical design considerations.</p>
