Description

<p>This RCBO (Residual Current Circuit Breaker with Overcurrent Protection) is designed for industrial and commercial applications, providing reliable protection by combining the functions of a circuit breaker and a residual current device in one compact unit. With a rated current of 20 A, it ensures efficient operation within your electrical systems.</p><p>The RCBO is engineered to handle a rated voltage of 415 V and features a robust breaking capacity of 10 kA, making it suitable for demanding environments where safety and reliability are paramount. It also boasts an impressive rated impulse withstand voltage of 4 kV and insulation voltage of 500 V, ensuring durability against transient overvoltages.</p><p>Featuring four poles, this device offers comprehensive coverage for three-phase systems. Its power loss is minimized at just 11.8 W, enhancing energy efficiency across operations. The RCBO&amp;#39;s electrical durability allows for up to 10,000 cycles, underscoring its long-lasting performance even under frequent use.</p><p>Conforming to standards IEC 61009-1/2-1 and EN 61009-1/2-1, this product meets rigorous international quality benchmarks. The degree of protection is IP2X, safeguarding against accidental contact with live parts while maintaining operational integrity.</p><p>With dimensions measuring 71 mm in width, 85 mm in height, and a depth of 69 mm—combined with a weight of only 480 g—the RCBO offers ease of installation without compromising on space or functionality. Its operating temperature range from -25&amp;#176;C to +55&amp;#176;C ensures adaptability across varied climatic conditions.</p><p>The short circuit capacity stands at an effective rate of 6 kA with the ability to handle cable cross-sections ranging from solid core to multi-wired configurations up to specified limits. This flexibility makes it adaptable for diverse wiring requirements.</p><p>Rated frequency options between 50/60 Hz cater to different regional grid specifications while the C curve type provides instantaneous tripping characteristics ideal for general-purpose applications including inductive loads like motors or transformers.</p><p>For enhanced safety measures, the residual current type is Type A which detects both AC and pulsating DC components up to a sensitivity threshold set at an industry-standard level—30 mA—providing critical protection against earth faults that could lead otherwise unnoticed hazards within installations.</p><p>Additional connectivity options include busbar connections capable up through rigid/flexible configurations allowing seamless integration into existing setups regardless complexity level involved therein; all backed by overvoltage category III classification ensuring resilience amidst challenging scenarios encountered during everyday usage periods alike!</p><p>Incorporating arbitrary power supply connection along undelayed earthing switch types further enhances versatility when deploying this vital component part any modern-day electrical infrastructure setup!</p>
