Description

<p>When it comes to selecting an RCBO (Residual Current Circuit Breaker with Overcurrent Protection) for industrial or commercial applications, understanding the technical specifications is crucial. This particular RCBO offers a comprehensive set of features tailored to meet rigorous safety and operational standards.</p><p>Rated at 50 A, this device ensures reliable protection against overcurrents while operating efficiently within its specified parameters. It can handle a rated impulse withstand voltage of 4 kV and possesses a rated insulation voltage of 500 V, making it suitable for high-demand environments. The device operates effectively in systems with voltages ranging from 400 to 415 VAC.</p><p>The RCBO’s power loss is calculated at 20.41 W, which reflects its efficiency during operation. With a configuration of three poles plus neutral (3P+N), it provides robust protection across multiple circuits.</p><p>In terms of physical dimensions, the product measures 53.4 mm in width, 117.5 mm in height, and has a depth of 71.6 mm — compact enough for most installation setups without compromising on performance.</p><p>This model adheres to important standards including IEC 61009-1, IEC 61009-2-2, and AS/NZS 61009-1, ensuring compliance with international safety regulations. The IP20 degree of protection makes it suitable for indoor use where exposure to dust or water is limited.</p><p>Weighing in at just over half a kilogram (0.549 kg), this RCBO is designed for durability with an electrical lifespan rated at up to 10,000 cycles and can withstand short circuit conditions up to 10 kA.</p><p>For wiring flexibility, it supports cable cross-sections ranging from solid-core cables between 1-25 sq-mm to multi-wired cables between 1-16 sq-mm. The connecting capacity includes busbar connections up to 10 sq-mm as well as rigid and flexible wire options similar in range.</p><p>Operating optimally within temperatures from -5&amp;#176;C to +55&amp;#176;C allows this device versatility across various climates found throughout Australia’s diverse regions. Its instantaneous operating characteristic ensures rapid response times when needed most.</p><p>Further enhancing its suitability for demanding applications is its Type A residual current type detection capability that provides additional sensitivity towards certain fault currents often encountered in modern installations featuring electronic equipment.</p><p>Designed with an overvoltage category III rating means it&amp;#39;s built tough enough for commercial settings where transient voltages might occur frequently due not only external factors but also internal system dynamics like motor starts/stops etc., adding another layer reliability overall system integrity assurance through effective earthing switch design characterized by undelayed action upon fault detection occurrence thereby minimizing potential damage associated prolonged exposure adverse conditions typically resulting increased downtime maintenance costs long-term perspective view operational continuity standpoint consideration factored into decision-making process selecting right fit your specific needs requirements contextually speaking practical sense Manufacturer Part Number: [Not Provided]</p>
