Description

<p>When considering an electronic overload relay for your industrial or commercial applications, the specifications and reliability of the device are paramount. This particular model offers a comprehensive set of features designed to meet rigorous operational demands.</p><p>Rated for a voltage of 690 VAC and a current setting range between 15-45 A, this relay is engineered to handle substantial electrical loads efficiently. It operates within standard frequencies of 50/60 Hz, ensuring compatibility with most power systems. The rated impulse withstand voltage is a robust 6 kV, making it suitable for environments prone to voltage spikes.</p><p>The relay&amp;#39;s contact configuration includes one normally closed (NC) and one normally open (NO) contact, providing flexibility in circuit design. Its trip classes—Class 10E, Class 20E, and Class 30E—offer different levels of protection against overloads based on application requirements.</p><p>With an IP20 degree of protection and IP3 degree of pollution rating, this relay is well-suited for indoor use where exposure to dust or moisture is minimal. The direct mounting type simplifies installation processes while maintaining secure attachment in various setups.</p><p>Size-wise, the relay measures a compact width of 45 mm by height of 104.7 mm by depth of 86 mm. This allows for easy integration into control panels without occupying excessive space. It operates reliably across temperatures ranging from -25&amp;#176;C to +70&amp;#176;C and can be stored safely between -50&amp;#176;C and +80&amp;#176;C.</p><p>Designed specifically for use with AF26-AF38 contactors, it ensures seamless compatibility within existing systems or new installations. For safety compliance and international applicability, it adheres to standards like IEC/EN 60947-1, IEC/EN 60947-4-1, IEC/EN 60947-5-1 as well as UL standards UL 60947-1 and UL 60947-4-1.</p><p>In terms of short circuit protection devices (SCPD), it supports up to a maximum current rating of 160 A using fuse type gG—a common choice in industrial settings due to its reliable performance under fault conditions.</p><p>Electrical connections are facilitated via screw terminals which offer secure fastening essential in high-vibration environments often found in industrial applications. The automatic reset function enhances ease-of-use by eliminating manual intervention after tripping events unless further investigation or maintenance is required.</p><p>Overall power loss stands at just around 0.059 W indicating energy efficiency—a critical factor in long-term operational cost reduction strategies especially when used extensively across multiple units within large-scale operations.</p><p>This electronic overload relay presents itself as an efficient solution balancing performance with practicality tailored towards those seeking durable components backed by stringent standards compliance—all vital considerations when evaluating potential purchases aimed at enhancing system integrity over time.</p>
