<p>When selecting a thermal overload relay for your industrial or commercial applications, it&#39;s crucial to have all the necessary details at hand. This thermal overload relay offers a robust solution with its comprehensive specifications tailored for demanding environments.</p><p>The device operates efficiently on a rated voltage of 690 VAC and supports both 50 and 60 Hz frequencies, making it versatile across different electrical systems. With a rated current of 0.55 A, it is well-suited for precise protection needs, minimizing power loss to just 1.3 W.</p><p>In terms of safety and reliability, this relay boasts a rated impulse withstand voltage of 6 kV and an insulation voltage matching the operating one at 690 VAC. Its contact configuration includes both normally closed (1NC) and normally open (1NO) contacts, providing flexibility in control circuit design.</p><p>Designed with durability in mind, the relay meets multiple international standards: IEC/EN 60947-1, IEC/EN 60947-4-1, IEC/EN 60947-5-1 as well as UL certifications. These approvals confirm its compliance with rigorous safety and performance benchmarks.</p><p>The trip class is Class 10, ensuring timely response under overload conditions while maintaining operational integrity within temperatures ranging from -25 to +60 degrees Celsius. For storage scenarios that demand resilience against extreme temperatures, it can withstand between -50 to +80 degrees Celsius.</p><p>With dimensions measuring a compact width of 45 mm by height of 76.7 mm by depth of 53.5 mm, this relay fits seamlessly into various setups without occupying excessive space. The direct mounting type facilitates straightforward installation alongside compatible devices such as B6 through VB7 series contactors among others listed.</p><p>Protection levels are specified at IP10/IP20 for physical ingress and IP3 for pollution degree which is suitable for most indoor environments where moderate exposure to contaminants might occur.</p><p>For enhanced protection against short circuits up to a maximum rating of 40 A using gG type fuses ensures additional safeguarding measures are in place during unforeseen events. Electrical connections via screw terminals offer secure attachment points reducing risks associated with loose wiring over time.</p><p>Finally equipped with an automatic reset function this model alleviates manual intervention requirements post-trip enabling smoother operational continuity when minor disturbances arise within specified current settings ranging from ten up till thirteen amperes allowing fine-tuning based on specific load characteristics encountered in service conditions faced regularly across diverse installations globally today!</p>
