Description

<p>When it comes to ensuring the safety and efficiency of your electrical systems, choosing the right thermal overload relay is crucial. This particular model offers a robust solution for protecting your motors from overheating due to overload conditions. Designed specifically for industrial and commercial applications, this thermal overload relay boasts a range of features that make it an ideal choice for those who prioritize reliability and precision.</p><p>Operating at a rated voltage of 690 VAC with a frequency compatibility of 50/60 Hz, this relay provides excellent adaptability across various electrical setups. The rated current stands at 0.55 A, while the setting range allows adjustments between 7.6-10 A, offering flexibility in application according to specific motor requirements.</p><p>One standout feature is its impressive power loss rating of just 1.1 W, which ensures energy efficiency during operation—an essential factor in minimizing operational costs over time. With a rated impulse withstand voltage of 6 kV and insulation voltage matching the operating voltage at 690 V, this device promises durability against transient voltages and reliable insulation properties.</p><p>The contact configuration includes both normally closed (NC) and normally open (NO) contacts (1NC+1NO), providing versatile control options within your system architecture. The trip class is designated as Class 10, meaning it delivers timely responses to overload situations without unnecessary delays.</p><p>Its degree of protection ranges from IP10 to IP20 depending on installation specifics—suitable for environments where basic protection against dust ingress is required but not exposed directly to water or moisture-laden atmospheres. Additionally, the degree of pollution classification as IP3 indicates suitability for environments with moderate levels of contaminants.</p><p>Mounting this relay is straightforward thanks to its direct mounting type design—a space-saving advantage given its dimensions: width at 45 mm, height at 88.3 mm, and depth measuring up to 70.5 mm.</p><p>In terms of environmental resilience, it operates efficiently within temperatures ranging from -25&amp;#176;C up to +60&amp;#176;C and can be stored safely between -50&amp;#176;C and +80&amp;#176;C—ideal for varied climatic conditions typically encountered in Australia’s diverse landscapes.</p><p>Compatibility with AF09-AF38 devices further enhances its integration potential within existing systems or when planning new installations. It meets rigorous standards such as IEC/EN 60947-1/-4-1/-5-1 along with UL certifications ensuring compliance with international safety benchmarks including IEC60335-2-40 A2L standardization pertinent towards refrigeration appliances using flammable refrigerants like A2L types.</p><p>For short circuit protection needs upholding robustness under fault conditions; use recommended protective devices like gG-type fuses rated up till max capacity limits reaching approximately thirty-five amps (35A).</p><p>The automatic reset function adds convenience by eliminating manual intervention post-tripping events thereby restoring normal operations seamlessly once fault conditions clear away naturally over time intervals predefined via class ten release specifications embedded inherently inside circuitry designs themselves!</p><p>Electrical connections are facilitated through screw terminals ensuring secure attachment points reducing risks associated commonly perceived otherwise if left
