<p>The S800HV series MCB (Miniature Circuit Breaker) is a robust solution designed for both commercial and industrial applications. This MCB stands out with its impressive electrical specifications and practical design features, making it suitable for various demanding environments.</p><p>With a rated current of 40 A, the S800HV ensures reliable operation under standard load conditions. It offers dual voltage capabilities with ratings of 580 VAC and 1000 VAC, providing flexibility in application across different voltage systems. The rated impulse withstand voltage is an impressive 8 kV, ensuring resilience against transient overvoltages.</p><p>Safety and durability are critical aspects of this MCB. It complies with IEC/EN 60947-2 and UL 1077 standards, guaranteeing adherence to international safety norms. The device has an IP20 degree of protection, which means it is protected against solid objects greater than 12 mm in size but not against water ingress.</p><p>The S800HV&#39;s release type is K, tailored for specific tripping characteristics suited to particular load types. Its breaking capacity at 1000 VAC is rated at a substantial 4 kA, while the short-circuit capacity stands at 2.5 kA—a testament to its ability to handle fault conditions effectively.</p><p>Physically compact yet sturdy, this MCB measures 54 mm in width, 142 mm in height, and has a depth of 82.5 mm—ideal dimensions for efficient space utilization within control panels or distribution boards. Installation is straightforward thanks to its DIN rail mounting capability.</p><p>Operational efficiency does not compromise on energy loss; the power loss rating sits at just 7.4 W. For wiring convenience, it accommodates cable cross sections up to 50 sq-mm on both top and bottom connections.</p><p>The tightening torque requirement for secure connections is specified at 3.5 N-m ensuring stability during operation without risking damage due to overtightening.</p><p>Temperature resilience ranges from -25&#176;C upwards making it suitable for diverse climates found across Australia—from cooler southern regions to warmer northern areas.</p><p>Its housing comes in RAL7035 Grey—a neutral tone that blends seamlessly into most industrial settings while maintaining professional aesthetics.</p><p>In terms of performance under environmental stressors like pollution or surges the product boasts an Overvoltage Category rating of III indicating strong resistance against high-energy disturbances commonly encountered in industrial setups.</p><p>Overall if you&#39;re seeking a dependable circuit protection solution that combines technical proficiency with ease-of-use consider integrating this versatile component into your system setup as part of the S800HV collection.</p>
