Description

<p>The RCBO (Residual Current Circuit Breaker with Overcurrent Protection) is a reliable choice for industrial and commercial applications, designed to ensure safety and efficiency in electrical systems. With a rated current of 20 A and the ability to withstand impulse voltages up to 4 kV, this device offers robust protection against overcurrents and earth faults.</p><p>This RCBO operates effectively at a rated voltage of 415 V and boasts an impressive breaking capacity of 10 kA, making it suitable for demanding environments. Its compact dimensions—71 mm in width, 85 mm in height, and 69 mm in depth—allow for easy integration into existing setups without requiring extensive space.</p><p>Engineered to meet international standards such as IEC 61009-1, IEC 61009-2-1, EN 61009-1, and EN 61009-2-1, this product ensures compliance with rigorous safety regulations. It features a degree of protection rated at IP2X, safeguarding against dust ingress while maintaining operational integrity.</p><p>With electrical durability rated at an outstanding 10,000 cycles and a short circuit capacity of 6 kA, this RCBO is built for longevity. The cable cross-section accommodates both solid core (25 sq-mm) and multi-wired configurations (up to four wires), providing flexibility for various installation requirements.</p><p>The device operates within an ambient temperature range from -25&amp;#176;C to +55&amp;#176;C, ensuring reliability across diverse climatic conditions. Additionally, its curve type C characteristic allows it to handle moderate levels of surge currents without tripping unnecessarily.</p><p>For residual current protection, the RCBO employs Type A technology with a sensitivity rating of 30 mA. This feature enhances safety by detecting alternating sinusoidal residual currents as well as pulsating DC residual currents.</p><p>Installation is straightforward thanks to its versatile connecting capacity; busbar connections support up to 10 sq-mm while rigid or flexible connections can accommodate between 25 sq-mm each. The power supply connection is arbitrary which adds convenience during setup.</p><p>Designed with an overvoltage category III classification and equipped with an undelayed earthing switch type alongside instantaneous operating characteristics – this product prioritizes quick response times essential for critical applications where downtime must be minimized effectively balancing performance needs against potential risks involved when dealing directly handling electricity supplies found within industrial settings today!</p>
