<p>When it comes to safeguarding your electrical systems from the risk of overload, this Thermal Overload Relay stands out as a dependable choice for industrial and commercial applications. This device is designed with precision to ensure that your equipment operates efficiently without succumbing to thermal stress.</p><p>Operating at a rated voltage of 690 VAC and accommodating a rated current of 0.55 A, this relay is engineered for robust performance in demanding environments. It supports both 50 Hz and 60 Hz frequencies, making it versatile across different power systems. The relay&#39;s power loss is minimal at just 1.1 W, which contributes to its energy-efficient operation.</p><p>A critical feature of this relay is its high rated impulse withstand voltage of 6 kV and insulation voltage rating also at 690 V, providing significant protection against transient overvoltage events. The contact configuration includes one normally closed (NC) and one normally open (NO) contact, offering flexibility in circuit design.</p><p>The setting range between 1.7-2.3 A allows for precise adjustment according to specific application needs, while the trip class is designated as Class 10, ensuring timely response under overload conditions. This relay provides dual degrees of protection: IP10 for general use and IP20 for enhanced safety against accidental contact or ingress by larger objects.</p><p>With direct mounting capabilities, installation becomes straightforward without requiring additional components or complex setup procedures. Its compact dimensions—45 mm in width, 88.3 mm in height, and a depth of 70.5 mm—ensure that it can fit into tight spaces within control panels or machinery housings.</p><p>Designed to operate effectively within an ambient temperature range from -25&#176;C to +60&#176;C, this relay remains reliable even under extreme conditions commonly encountered in industrial settings. Furthermore, it has been tested and approved under rigorous standards including IEC/EN 60947-1/4-1/5-1 and UL certifications among others.</p><p>This product pairs seamlessly with AF09-AF38 contactors and features automatic reset functionality for ease of use after tripping events due to overloads—reducing downtime significantly compared with manual resets required by some alternatives on the market today.</p><p>For added peace-of-mind regarding safety compliance during short-circuit scenarios up till currents reach levels protected by devices such as fuses type gG rated at around ten amps; these attributes make sure you’re covered no matter what challenge arises next! </p><p>Finally if storage considerations come into play then rest assured knowing temperatures ranging all way down minus fifty degrees Celsius up eighty above zero won’t pose problems thanks careful engineering behind every aspect construction process involved here too!</p><p>Manufacturer Part Number: [Not Provided]</p>
